The WHO Forum on Traditional Medicine in Health Systems, Zimbabwe, Harare, February 14-18, 2000.

Journal of Alternative and Complementary Medicine. 2000, Vol.6(5) Oct. 2000, pp.379-382.

Preparation for the WHO African Forum

Most readers of this journal know that the World Health Assembly of the World Health Organization passed a resolution in 1977 promoting the development of training and research related to traditional medicine. The following year in Alma Ata, WHO and UNICEF issued additional resolutions supporting the use of indigenous health practitioners in government-sponsored health programs.

In preparation for the African Forum on the Role of Traditional Medicine in Health Systems (Harare, February 16-18, 2000), WHO's Regional Office for Africa had earlier (1998) submitted a questionnaire to its 46 member states. A completed questionnaire was received from 30 of the countries. Although 35 percent of countries did not respond and it was not possible to verify validity of answers submitted, the findings nevertheless shed light on the Africa-wide situation regarding traditional medicine and practitioners.

Findings suggest that a national management or coordination body for Traditional Medicine activities exists in 17 of the 30 countries (57%). Twenty-two countries (73%) indicated that associations of traditional medicine practitioners (TMPs) have been established. Ten countries (33%) indicated that a directory of TMPs exists. Four countries (13%) indicated that a training program for TMPs exists, and 17 countries had such programs for traditional birth attendants (TBAs) (WHO 1999).

There were many other findings from this survey that will probably be published in more detail by the WHO. The survey findings were sent to the delegates invited to the Forum prior to the meeting, to set the stage for assessments of how far traditional medicine has come since 1977, and for discussions about where to go from here. Much organizational work was done before and during the Forum by Dr. O.M.J. Kasilo, Acting Regional Advisor for Africa, WHO Traditional Medicine Programme. She also provided a great deal of leadership during the conference.

The WHO African Forum Itself

Delegates invited to the Forum represented most of the countries of Africa. A majority were connected with ministries of health or other government agencies, or with university departments of pharmacology or chemistry. A number of traditional healers were also present, mostly representing national traditional healers' associations.

In an opening plenary speech, Dr. Ebrahim Samba, Regional Director, Regional WHO for Africa, told the delegates that there is keen interest on the part of WHO in the mass production of phytomedicines for the treatment of malaria, AIDS, and other diseases identified as priority diseases by member states. It is a strategic objective of the WHO to develop a framework for the integration of traditional medicine into national health systems. The idea is to encourage local industry to invest in the local production of indigenous medicines, and make them commercially viable. Governments should create policies related to conservation, safety and toxicity, and phytomedicine regulation in order to assist local production industry. If outside funding is necessary, both the African Development Bank (ADB) and the WHO are possible sources. The ADB now invests more money in Africa than the World Bank, and it too has become very interested in traditional medicine.

There has been relatively little mass-production, promotion and distribution of phytomedicines in Africa. However, countries such as Nigeria and Mali seem quite advanced in this regard. For example, Nigeria has developed phytomedicines for ulcers, anemia, contraception, malaria and HIV, and it now holds patents for some of these medicines in several countries. Nigeria is about to have two phytomedicines registered with the MOH there: one for HIV and one for sickle cell anemia. Dr. Charles Wambebe, Director General of the National Institute for Pharmaceutical Research and Development (NIPRD) in Abuja, Nigeria, gave a fascinating presentation about the development of two phytomedicines. Both were developed from herbal medicines obtained from local traditional healers. The NIPRD followed a procedure in which the traditional healers and their patients sign consent forms, allowing study of the phtomedicine and the effects on patients. In phase 1 placebo-assisted clinical trails, patients were given the experimental phytomedicines for both sickle cell anemia and for HIV. After three months, patients in the experimental group were found to be improving. The clinical trials are continuing. The NIPRD is also targeting malaria, and is starting a pilot clinical trial of a new antimalarial phytomedicine in July 2000.

The HIV/AIDS phytomedicine is called Dopravil. From preliminary anecdotal and experimental evidence, this new compound looks promising. But since research results will no doubt be published, I will confine my comments to the NIPRD's plan for recognizing the intellectual property rights of traditional healers by means of a scheme for sharing any future royalties from a phytomedicine that becomes a profitable drug (or patentable comound). For most of the history of drug development in which initial drug discovery leads came from indigenous healers, both the healers and their communities received no benefit.

Dr. Wambebe was very eager to talk about this often-ignored issue. He gave me a copy of a Consultancy Agreement between the NIPRD and traditional healers who serve as consultants and provide phytomedicines they are already using. When a healer signs this contract, she becomes eligible for three types of benefits: an on-going consultant fee during the clinical trial phases; a share of future royalties "amounting to at least 10 percent" of net profit, or a one-time payment in lieu of on-going royalties. Nigerian researchers found that healers are more likely to cooperate if they are able to gain something from the relationship here and now, and not have to wait until some future date when there may or may not be royalties.

Development of an African Phytomedicine Industry

Some delegates made the point that the high Western standards of testing new drugs, costing in the neighborhood of at least four hundred million dollars and taking 20 years, can never be used in Africa. Dr. Gerard Bodeker (from GIFTS of Health, Oxford, UK) and others argued for a quicker research strategy based on affordable, appropriate technology (Bodeker calls it Rapid Response Research) that can allow the development of crude extracts through a process of research that results in either a synthetic drug, or at least a complex phytomedicine that can be approved, mass-produced, widely distributed in-country and exported to the world market. Another idea discussed was to develop something like the German Commission E monographs which establish toxicity, dosage and use, and which document that a herbal medicine has already been widely used for many years. The hope was that Africa can develop and export indigenous phytomedicines, just the USA and Europe export herbal tablets such as St. John's Wort and Echinecea to the rest of the world.

The cultivation, mass-production, local distribution and export of African phytomedicines could help reduce dependency on expensive Western pharmaceuticals (saving money for other purposes), help take care of the health needs of Africans, and develop much-needed local industries. But this is far from easy to accomplish. As became clear from presentations and discussions, local production of phytomedicines requires a complex partnership between groups such as the WHO, the ADB, ministries of health and agriculture of member countries, local businesses, agricultural interests, local regulatory officials, environmentalists, traditional healer associations, etc. A complicating factor is that there is major asymmetry in levels of education, power and resources among these partners. Moreover, a regulatory framework is needed to guide advertising, sales, manufacture, and distribution of phytomedicines. There is also a need for testing plant medicines for heavy medals, pesticides and microbial contamination. Development of an African phytomedicine industry furthermore requires an environment of political support and popular acceptance, not easy to achieve.

Private Sector African Medicine

There had been several comments throughout the Forum about how nothing is possible without funds from donors or governments. On the last day of the conference, professor M. Gundidza from the University of Zimbabwe (dept. of Pharmacy) stood up and made a powerful point about resources available in the private sector. He started by asking for a show of hands to see how many people present actually consulted traditional healers. At first virtually no hands were raised. He urged us further, saying that we needed to be honest and put our hands up if we ever consulted traditional healers. A few hands finally went up, perhaps no more than 10 percent of the audience. The professor said this proved the point he wanted to make: We come together at conferences like this to extol traditional medicine, and yet deep down, we regard it as second-class. He has asked his colleagues why they don't use traditional medicine or go to healers and their favorite answer is "that traditional healers have no training."

To remedy this, this professor teaches naturopathic medicine at the University of Zimbabwe. He asked two of his recent graduates to stand up and take a bow, which they did. He then mentioned that a couple of other graduates had wanted to be at the Forum but their clinics were so full of patients waiting for treatment that they simply couldn't get away. He said (and I paraphrase from my notes):

"This is homegrown African enterprise! Why wait for the World Health Organization to help us? The WHO has no money! Come and see our clinic. Our students come from O- and A-level high school graduates whom I then train at various levels: certificate, graduate, post-graduate. They learn complementary and alternative medicine. They learn physiology, anatomy, hygiene, and more. You say you feel that traditional healers aren't properly trained. Well, that's why we are here! To train Africans more comprehensively and systematically."

This made the point dramatically that there is plenty of money to be made in and through the private sector in traditional medicine. Millions of people, rich and poor, in Africa and elsewhere, are ready to pay for treatment with herbal and other natural medicines. Not that this example necessarily solves the problems of mass production, conservation, forming complex partnerships, etc. But Dr Samba made a strong, eloquent speech at the end of the conference about the need for private sector initiative. Such initiative will need to be demonstrated to attract donor support from the likes of the WHO or the African Development Bank.

Alternative and Complementary Medicine at the 1998 World AIDS Conference

Journal of Alternative and Complementary Medicine, Vol.4(3) 1998, pp 349-351.

While the general tone of the 12th World AIDS Conference held in Geneva was somber, due to increasing failure rates of combinations of antiretroviral drugs, the mood was very different for those interested in, or using, alternative and complementary therapies.

A number of scientific papers were presented demonstrating the value of herbal and other "unorthodox" treatments for HIV-related syndromes, and for HIV itself. For example, controlled studies of Chinese and Thai phytomedicines both showed inhibition of HIV, increased immune function, enhanced CD4 cell counts, and increased survival rates of those tested as HIV-positive (abstracts are available for all such papers).

It was hard not to encounter long-term survivors of HIV/AIDS at the conference; one needed to look no further than a special symposium convened for them. Long-term survivors are those living with the HIV virus for 10 or more years. What impressed me most about the conference was the number of these survivors that have been relying on indigenous (or "traditional") medicines and therapies (if they were from developing countries), or on alternative and complementary medicines and therapies if they were from so-called developed countries.

There seemed to be fewer PWAs (persons with AIDS) from poor, developing countries, no doubt because of the prohibitive expense of flying to Europe and paying the hefty conference registration fee. But there were some, and there were also many healthy PWAs from developed countries who have been living with HIV for 10-18 years. We can use PWAs' own definition of healthy: feeling generally well and energetic, and having no symptoms of AIDS. Some men and women had relatively high CD4 levels and low viral loads. Others had less desirable test values, but most seemed not to let themselves become very concerned with such test results. Some were aware that Kary Mullis, Nobel-prize winning biochemist and inventor of the PCR test used to measure "viral load" of HIV, has repeatedly criticized the use of his invention as an accurate measure of the amount of HIV circulating in the body.

At least a dozen survivors I chanced to meet have chosen not to take conventional antiretroviral drugs of any sort, singly or in "combo cocktails." Instead, they rely on a range of other therapies, including herbs, nutrition, yoga, acupuncture, exercise regimens, homeopathy, massage, and movement therapy, among others. A number (but not all) had stopped smoking and drinking alcohol and had opted for generally healthy lifestyles. Many were of the opinion that their greatest strength was simply not believing that an HIV diagnosis means a death sentence. They had positive attitudes and faith in the future.

Since I was in Geneva to participate in a symposium on alternative and complementary medicine, and I met some of these healthy long-term survivors in connection with this symposium, there was no doubt a bias in favor of my encountering PWAs who favor indigenous or alternative therapies. But I met about half of those I spoke with through chance encounters. Many of the total felt that their numbers were not reflected in official medical statistics since they do not participate in clinical trials and many do not even consult conventional doctors. They virtually all felt that the unconventional therapies they were following, through self-treatment and consulting alternative practitioners, were not adequately reflected by the single two-and-a-half hour Community Symposium (which means not on the "scientific track") that was allotted by the conference organizers. Its title was Alternative and Traditional Healing Practices, and it was co-chaired by Kaiya Montaocean and Xevi Garcia Flores. Others not living with HIV but conducting research in a variety of areas considered unconventional agreed with this assessment, as did many other delegates who have themselves found value in unconventional therapies.

As a result of the foregoing and the "Alternative" symposium itself, the following Declaration was developed and officially presented to:

The Global Network of People Living with HIV/AIDS (GNP+)
The International AIDS Society (IAS)
The International Council of AIDS Service Organizations (ICASO)
The International Community of Women Living with HIV/AIDS (ICW)
The Joint United Nations Programme on HIV/AIDS (UNAIDS)
The Government of the Republique et Canton de Geneve

Declaration on Traditional, Alternative and Complementary Medicine

Recognizing that in developing countries (the "south"):

• Some 90% of people rely on indigenous, natural medicine either through self-treatment or treatment by traditional medical practitioners;
  
• Natural medicines have been found to be effective in the treatment of some of the opportunistic infections associated with HIV,
  
• Pharmaceutical drugs, especially antiretrovirals are beyond the reach of most of the world's poor;
  
• A number of pilot projects and ongoing health programs have shown that traditional medical practitioners can collaborate with biomedical personnel to help prevent the spread of HIV and STIs (by promoting partner reduction, safer sex, condoms, sterilization of razor blades, etc)
  
• Traditional healers are in a unique position to provide individualized and home-based care and counseling and holistic treatment for HIV+ and AIDS patients;

Recognizing that in industrialized countries (the "north"):

• Often 50% or more of populations (e.g., in the USA, Germany, Australia) use some form of "alternative or complementary medicine" such as medicinal herbs, nutritional therapy, homeopathy, acupuncture, chiropractic, massage, dance or movement therapy,
  
• Individuals with HIV and AIDS often rely on such alternative medicines to relieve suffering associated with either the disease or the symptoms of antiretroviral treatment,
  
• Some living with HIV/AIDS, including long-term survivors, rely exclusively on alternative therapies, either because of drug resistance, drug failure, or personal choice;

And recognizing that traditional, alternative and complementary medicine receive small fraction of 1% of global health funds with less than half of that targeted to HIV/AIDS, in spite of the fact that a majority of people living with HIV use traditional or “alternative,” complementary medicines,

1. We resolve the role of natural medicines and traditional medical practitioners, as well as alternative and complementary medicines, be acknowledged in AIDS prevention and treatment, and therefore this health sector should be allocated an equitable share of AIDS research, treatment and prevention resources.
   
2. We resolve that venues and tracks be set aside at regional and international AIDS conferences for the exchange of ideas and experiences related to traditional and alternative therapies, and that regional and global networks be supported.

The natural, Alternative, Traditional and Complementary Medicines (NATC) Caucus of the International AIDS Society (IAS) will be responsible for follow-up on the response to this Declaration, and for promoting these resolutions.

The Declaration was accepted for publication in the official conference report.

Incidentally, there was so much interest in the Symposium on Alternative and Traditional Healing Practices that participants requested, and were granted, a conference room the following day for a continuation of discussions begun earlier. Some 40 people showed up and stayed for another 3 hours, during which plans were discussed for more and larger alternative medicine symposia to be held in Durban, South Africa, the World AIDS Conference site for the year 2000.

There is hardly a developed country where health care reform has not become a kind of chronic disease of modern medicine: as soon as some reforms are implemented, a call comes for yet another round. Costs continue to climb, but nothing seems to contain their growth for very long.

Why? Politics surely plays a role. But a more fundamental reason is the nature of modern medicine itself. Most developed countries have a growing number and proportion of elderly. Since health care costs for those over 65 are approximately four times higher than for those under 65, aging societies place massive claims on medical resources.

This is compounded by the constant introduction of new (and usually more expensive) technologies, together with increased demand for high-quality health care. We want more, expect more, and complain more loudly if we don't get it. When we do get it, we quickly raise the bar, wanting still more.

The net result has been an average general system-wide cost increase of 10%-15% annually in the United States for the past several years--and with no end in sight. European countries are under severe cost pressures as well, undermining their cherished ideal of equitable access.

Unfortunately, greater use of co-payments and deductibles, privatization of health-care infrastructure, and waiting lists for elective surgery and other non-emergency care are unlikely to work much better in the future than they have in the past. What is needed is a radical change in how we think about medicine and health care, not simply better ways to reorganize existing systems. We need a "sustainable medicine" that is affordable to national health care systems and provides equitable access in the long term.

The notion of "sustainability" comes from environmentalism, which seeks to protect the earth and its atmosphere in order to sustain indefinitely human life of a good quality. As with environmentalism, sustainable medicine requires reformulating the idea of progress that drives technology costs and fuels public demand. The Western idea of progress, translated to medicine, sets no limits on the improvement of health, defined as the reduction of mortality and the relief of all medical miseries. However much health improves, it will never be sufficient--so further progress is always required.

But unlimited progress cannot be paid for with finite funds. Long-term affordability and equitable access requires a finite vision of medicine and health care, one that does not try to overcome aging, death, and disease, but tries to help everyone avoid a premature death and to live decent, even if not perfect, lives.

This implies shifting medical resources sharply towards health promotion and disease prevention. Billions of dollars have been spent on mapping the human genome. Comparable sums must be spent on understanding and changing health behaviors that are most likely to bring about disease. Why is obesity increasing almost everywhere? Why do so many people continue smoking? Why is it so difficult to persuade contemporary people to exercise?

Sustainable medicine also requires comparing health care expenditure with spending on other socially important goods. In a balanced society, health care may not always be the top priority. At the same time, we often overlook the health benefits of spending money in ways that have nothing to do with the direct delivery of medical care: education and health, for example, are strongly correlated: the higher the former the better the latter.

In any case, sustainable medicine acknowledges that rationing is and always will be a part of any health care system. No system can give everyone everything they need. Our aspirations will always exceed our resources, particularly since medical progress itself raises public expectations. But, to be fair, rationing requires the knowledge and general consent of all who are subject to it.

One place to start is to evaluate the economic impact of new technologies, preferably before they are released to the public. Evidence-based medicine--a popular technique for controlling costs--is ordinarily aimed only at the efficacy of diagnostic or therapeutic procedures. But if drug companies must test new products for their safety and efficacy, why not also for their economic impact on health care? New technologies should not be dropped into health care systems uninvited. Only if a technology does not significantly raise costs, or does so only exceptionally, should governments be willing to pay for it.

Most fundamentally, a finite model of medicine must accept human aging and death as part of the human life cycle, not some kind of preventable condition. Medicine must shift its focus from length of life to quality of life. A medicine that keeps people alive too long is not a decent and humane medicine. We can live to be 85, but we are likely to do so with chronic conditions that leave us sick and in pain.

This is not an argument against progress: I, for one, am glad that people don't die of small pox at 40 anymore. But aging and death will still win out in the end. Medical progress is like exploring outer space: no matter how far we go, we can go further. With space travel, the economic limitations of unlimited exploration soon became obvious: no more moon walks. Medicine needs an analogous insight.

Slower technological progress may seem a high price to pay for sustainable health care. But our current systems carry an even higher price, threatening justice and social stability. At the same time, only about 40% of the rise in health status over the past century is attributable to medical progress, with the rest reflecting improved social and economic conditions. This trend is likely to continue, so that even if technological progress slows, people are almost certain to live longer lives in the future--and in better health--than they do now. That outcome should be acceptable to everyone.

Poverty Does Not Mean that Effective AIDS Prevention Is Impossible

One often reads and hears nowadays that poverty underlies AIDS, or at least that poverty drives the epidemic. The same is often said of marginalizion. In a recent article, Richard Parker comments, “In all societies, regardless of their degree of development or prosperity, the HIV/AIDS epidemic continues to rage, but it now affects almost exclusively the most marginalized sectors of society.” That presumably means that those primarily infected with HIV may not always be poor, but they are likely to be marginlized, that is, members of groups on the margins of society, such as IDUs, men who have sex with men, commercial sex workers, or racial minorities. This may be true for the United States and Brazil (where Parker has done much AIDS work), but it this is not an accurate statement for Africa.

Let us consider the first proposition. One explanation for why poverty causes or underlies AIDS is that poor women turn to sex work, putting themselves and their partners at risk, risk that would no exist if such women had not had to resort to sex work. Another argument is heard less often, namely that poverty leads to poor nutrition, which makes may make people shed more viruses and be more infective if they are already HIV-positive (Stillwagon 2002). Or that poor nutrition and weakened immune systems (more related to concurrent infections than to poor nutrition) makes people more susceptible to HIV infection in the first place (Root-Bernstein 1993). Those who accept that poverty underlies AIDS proposition uncritically can be led to proposing AIDS prevention solutions such as “forgive Africa’s debt” and “overthrow the World Bank.”

We see at once that there must be more to the story, at least in Africa, because the wealthiest African countries (South Africa, Botswana, Swaziland, and until very recently, Zimbabwe) in fact have the highest HIV infection rates on the continent (25-40%), not the lowest as we might expect. Meanwhile, some of the poorest countries (Somalia, Guinea, Liberia, Mali, Eritrea) have among the lowest rates (under 3%). Certainly the two African countries that stand out as successful in reversing the direction of HIV infection rates, Uganda an Senegal, cannot be called wealthy. Uganda’s GNP per capita income is about $240, while Senegal is under $240 (Sittitrai 2001).

In fact, there is growing evidence that affluence rather than poverty can drive local HIV epidemics. Several studies in Africa (e.g. Over and Piot, 1993; Smith et al 1999; Vandemoortele and Delamonica 2000) have shown that there is an association between increased education and income, increased HIV risk behaviors, and increased HIV infection. And, not so incidentally, with increased use of condoms. In pondering the notion of an “education vaccine” against AIDS, Vandemoortele and Delamonica (2001:1) note:

An inverse association between the disease burden and the level of education exists for most infectious diseases. The incidence of malaria and cholera, for instance, are known to be negatively associated with the level of education. But because of its main propagation channel, HIV/AIDS first affects those with more opportunities, including more educated, mobile and better-off people.

“Better-off” of course means those with higher incomes. The authors note that it is often observed that men who wear a tie do not get cholera. Yet these are often the men in Africa who are most likely to become HIV infected. One even hears of the "three Cs" risk factors for AIDS - cash, car and cell phone (Altenroxel 2003). But why? It appears that higher incomes allow men to pay for commercial or transactional sex or, as is more often the case in Africa, simply to have many sexual partners. A taxi driver in Guinea Bissau might have preempted this whole poverty/AIDS debate in 1987, when he explained to a visiting New Yorker journalist that in Africa, “The more money you have, the more women you can get.” And he made clear was not talking about commercial sex in the usual, Western sense (Shoumatoff 1988:155).

Vandemoortele and Delamonica (2001:2) note that a direct relationship between education and HIV infection rates (i.e.. higher levels of education are associated with higher HIV infection rates) tends to be found in countries with high HIV prevalence, whereas there tends to be an inverse relationship in low-prevalence countries. Hence the difference we see between Sub-Saharan Africa and, say, Brazil. Others have suggested that the direct relationship between education and HIV infection might only characterizes countries in the early stages of an HIV epidemic, that as an epidemic becomes mature, we no longer see it. Yet studies of populations with mature epidemics often show continuation of the direct relationship. For example, in one study, American and Ugandan researchers examined the association between education (usually linked to income) and HIV prevalence in rural Rakai district, Uganda, based on a cross-sectional analysis of a randomly selected, population-based cohort. The Rakai HIV epidemic must be one of the most mature in the world. They found:

Higher levels of education were associated with a higher HIV seroprevalence in bivariate analyses (OR 2.7 for primary and 4.1 for secondary education, relative to no education). The strength of the association was diminished but remained statistically significant after multivariate adjustment for soicodemographic and behavioural variables (adjusted OR of HIV infection 1.6 (95% CI: 1.2-2.1) for primary education and 1.5 (95% CI: 1.0-2.2) for secondary education (Smith et al 1999:452)

The authors conclude that higher educational attainment is associated with higher incomes which in turn “facilitate behavious that place individuals at greater risk,” such as more travel and having multiple sex partners (Smith et al 1999:457).

Another random sample, population-based study of socioeconomic status (defined by possessions, acreage, housing quality and education) and HIV infection was also conducted in Rakai. The researchers found that “Higher economic status and certain occupations were consistently associated with more partners (lifetime or within last year) and higher levels of concurrent partnerships for both sexes.” (Ssengonzi et al 1996)

A study of socioeconomic status and HIV prevalence among pregnant women in Dar es Salaam, likewise found that “…women of higher socioeconomic status in Dar es Salaam were at greater risk of HIV infection “ (Msamanga et al 1996). Other studies show that lower education and other SES (socioeconomic status) indicators are associated with greater risk behaviors, such as not using condoms, but this may not translate into higher HIV infection rates, at least in Africa. Elsewhere, such as Brazil (Veloso et al 1998), there tends to be a relationship between lower SES and higher HIV infection rates.

Carael, Cleland and Deheneffe (1995) reviewed sample surveys conducted in 1989-1993 of male and female respondents aged 15-49 years reporting sex with a nonregular partner in the preceding year. Significant positive associations between educational level and risk behavior were found among women as well as men in about half the studies.

And in the most recent national sentinel surveillance study in Zambia, HIV prevalence still clearly increases with level of education and ranges from 13 percent in women with less than primary education to 26 percent among those with college/university education (Table 1, following) (SIDA/CDC 2003:26).

Table 1. Trends in HIV Prevalence for Women attending Antenatal Care by Type of Site and Level of Education Completed

This topic was discussed at a regional conference held in Nairobi to discuss young women and HIV/AIDS in Eastern and Southern Africa. From a conference summary posted on

This e-mail address is being protected from spam bots, you need JavaScript enabled to view it (12/19/02):

The role of education was discussed at length by F. Malola from Malawi. In a presentation that proved to be controversial to some, he outlined how education has contributed to the spread of HIV - not only through providing a venue for men and women to meet but also that with education one is able to secure employment thus money "to woo girls into sexual relations." Much debate was spurred, in and out of session halls, if it was just location (e.g. schools, university) that was the risk factor or the impact of being educated itself.

Some who argue very publicly that poverty drives AIDS epidemics might concede that in Africa, wealth may be even more of a risk factor than poverty for men, but not for women. We have just seen some data that show that SES may be associated with higher HIV infection among women as well. But what about the increased risk of women driven to prostitution or transactional sex by poverty? Even this may be more complicated than it appears. Chin and colleagues (Chin, Bennett, Mills 1998) showed that level of FSW (female sex worker) customer turnover (the average of number of clients per week) is a major factor explaining HIV infection levels, at least in Asia. One of the reasons that HIV infection levels remain below 1% among sex workers in the Philippines is that they have an average of 2-3 clients per week, compared to more than this per day in some countries. When I was evaluating the impact of AIDS prevention programs in the Philippines in 2001, infection rates among FSWs were still below 1%, in spite of significant economic decline in the previous 2 years. It appeared from interviews my colleagues and I conduced and from available data that while more Filipina women had turned to commercial sex, the number of male clients was the same, or even lower, due to the weak economy and perhaps to the effects of AIDS preventive education. This meant that the number of clients per women was even lower than it had been before. This would prevent infection rates among CSWs from rising. Incidence, if someone took the trouble to measure this, might even decline, assuming other contributing factors remained roughly the same.

On the other hand, poverty may be one of the “causes” of the “sugar daddy” phenomenon in Africa, Jamaica, and elsewhere. This refers to older men offering gifts of cash or kind to young unmarried women in exchange for sexual favors. This has become sufficiently widespread that it often provokes little or no negative social sanction (Gupta and Mahy 2001). In fact, a good deal of female sexual behavior in Africa can best be understood as strategies for economic survival and adaptation to patterns of male dominance in low-income countries (Cohen and Trussell 1996:120; Guyer 1994; Green 1994: 99-100). As Barnett and Blakie (1992) have summarized it, African women gain access to economic resources through a range of sexual relationships with men, including monogamous and polygamous marriage, long-term relationships lacking de jure recognition, stable non-resident relationships involving visits on a regular basis, casual liaisons, and the type of commercial prostitution familiar in industrialized countries.

The economic transaction may not be the main or express aspect of the relationship for the participants, but given women's underlying unequal access to economic resources, sexual favours and reproductive potential are powerful resources--sometimes the only resources--on their side of the transaction (Barnett and Blakie 1992:77-8).

Thus, we see widespread a pattern of transactional sex that is not the same as commercial sex in Asia or elsewhere. This is said to be a pattern driving the epidemic in Cameroon, which has one of the highest levels of infection in the West African region (Calvez 1999).

None of this is to argue that there is no relationship between poverty and HIV infection levels, or becoming HIV infected. But it is not the simple, unidirectional casual relationship that is usually presented. We have already seen that greater income can, through various mediating factors, underlie higher HIV infection rates. Poverty can lead or even force women into sex work, but poverty can also greatly limit the number of customers, and the proportion of men who are clients of sex workers. There seems to be a relationship between drug abuse and poverty, so it might be said that poverty, along with other social factors, can contribute to the high numbers of injecting drug users who are then at high risk of acquiring an HIV infection (Chin 2002). Thus, the evidence suggests that any relationship between poverty and AIDS is complex and multi-directional.

Another part of the issue is that poverty is a difficult factor to influence. Part of the value of the National Research Council table of epidemiologic factors relevant in generalized HIV transmission areas (Cohen and Trussel 1996, Fig. 1, next page) is that it reminds us that some desirable changes may not be achievable in the short or medium term, to use the language of the table. For example, poverty, unemployment and gender inequality are the aspects of AIDS that occupy the attention of many or most American anthropologists concerned with international AIDS (cf. Schoepf 2001). Yet it could be argued that little will result from denouncing poverty, at least not as much as putting into place effective, workable prevention programs. In fact, poverty and inequality are an easy set of factors to invoke, since one can argue on the side of the angels yet little can be done to change these factors during anyone’s lifetime. For example, it has long been recognized that poverty and gender inequality underlie high fertility and associated problems, and that poverty and unemployment provide the conditions for child diarrheal disease. Yet during the decades this has been known, poverty and unemployment have become worse, not better, in Africa.

It is fine to denounce the evils of poverty, and better still to work actively to change the broader social and institutional systems that need changing. But let this not keep us from finding better ways in the short and medium term to prevent HIV transmission, even if delay of sexual debut does not have quite the same visceral appeal as “end poverty, racism, gender inequality and homophobia NOW!” Certainly when I was a sophomore, I never would have attended a rally centered on the theme of delay of sexual debut.

The Rev. Eugene Rivers, an African-American social justice and AIDS activist from Boston, met with religious leaders and others in June 2002 in Abuja, Nigeria to discuss that country’s response to AIDS. There was discussion and debate about the “true root causes" of AIDS, i.e., poverty, the status of women, crushing external debts, lack of education, and the like. According to a US Embassy cable describing the event, “Rivers agreed that all these issues must be addressed, but he said there was no time to wait for root causes to be solved. This focus was a distraction or an excuse for no action. The immediate prospect of death for so many millions required immediate, direct action.”

This reflects my position. I don’t support the simplistic belief that AIDS is caused or driven by poverty, but this in no way means I am against overcoming poverty, nor that poverty does not exacerbate HIV epidemics in some ways. We should all be against social and economic ills, but let this not be confused with a sound AIDS prevention strategy.

A new UN report, entitled AIDS in Africa, was compiled over two years using more than 150 experts. It warns that 10% of Africans (an additional 90 million people) could be infected with HIV within the next 2 decades.

Coca Cola was invented in the United States in 1886 as a medicine, rather than a drink, to stimulate the brain and the nervous system, from a mixture of coca leaves and kola nuts, sweetened with sugar, hence the name Coca Cola. It was not until 1893 that Coca Cola was sold and promoted as a drink. Gradually the cocaine was eliminated, but in order to maintain the stimulant effect caffeine was substituted.
