How WHO (World Health Organization) defines HIV/AIDS
In the West: AIDS is defined as the appearance of one or more of 30 "opportunistic infections" together with positive HIV test. Opportunistic infections include tuberculosis, hepatitis, pneumocystis carinii pneumonia, candida, cryptococcal meningitis, Kaposi's sarcoma, etc.
In Africa: AIDS case in Africa is a combination of fever, persistent cough, diarrhea and a 10-per-cent loss of body weight in two months. No HIV test is needed.
[These symptoms are also characteristic of malaria, tuberculosis, dysentery and other indigenous diseases of impoverished lands. These diseases have been "redefined" as AIDS. The problem is that dysentery and malaria do not yield headlines or fatten public-health budgets. “Plagues” and infectious diseases do.
Geshekter, California State University, Chico, and a policy advisor to the US Government, points out thatthose who question AIDS in Africa put their own funding at risk. I saw this at first-hand when I visited Swaziland in mid-December at the invitation of their HIV/AIDS Crisis Management Committee. I was driven from the airport to the hotel in a late model 4-wheel drive vehicle. It had been donated by UNICEF and was covered with AIDS posters urging Swazis to “use a condom, save a life.” The committee included representatives of the major government ministries, as well as church and women's groups.
... an attorney named Teresa Mlangeni acknowledged that she could easily see how malnutrition, tuberculosis, malaria and other parasitic infections — not sexual behaviour — were making her fellow Swazis ill. But other committee members confided that if they voiced public doubts, they risked losing their international funding. And I realized that the vested interests of the international AIDS orthodoxy would discourage further inquiries.Since 1994, tuberculosis itself has been considered an AIDS-indicator disease in Africa.
Geshekter says the most reliable statistics on AIDS in Africa are found in the WHO's Weekly Epidemiological Record. The total cumulative number of AIDS cases reported in Africa since 1982, when AIDS record-keeping began, is 794,444 — a number starkly at odds with the latest scare figures, which claim 2.3 million AIDS deaths throughout Africa for 1999 alone.
An example of scare figures from the AIDS Conference held in Durban, South Africa in July 2000:
"The latest report by the United Nations Program on HIV/AIDS (UNAIDS) says that nearly 20 percent of adult South Africans are infected with the AIDS virus, predicting that half of all 15-year-olds will eventually die of it. The impact on South Africa’s already struggling economy will be disastrous.
Up to one in four adults in central Johannesburg are infected, according to the city’s Southern Metropolitan Local Council." [Reuters to ABC News.com, July 8, 2000]
Examine and compare these two accounts of AIDS in Botswana - May 15 and July 10, 2000
Agence France-Presse - May 15, 2000
GABORONE, May 15 (AFP) - The HIV/AIDS epidemic will curb the growth of the economy of Botswana by about a third over the next ten years, according to a government-commissioned report published Monday. The report projects that over the next decade the diamond-rich country's economy will be 31 percent smaller than it would have been without the disease.
One in four economically active adults in Botswana have tested HIV positive, the report by the independent Botswana Institute for Development Policy Analysis said. This translates into one fifth of the country's 1.5 million people.
The report said that HIV/AIDS will cut the gross domestic product, currently around four percent, by 1.5 percent over the next five years. It will also cause a shortage of skilled workers, pushing skilled wages up by between 12 and 17 percent.ABC in AIDS in Africa July 10 - World AIDS Conference July 5-12, 2000
"In Botswana, the world’s worst-hit country, more than one-third of all adults
carry the virus."Table on AIDS in Africa gives these figures for Botswana:
- Total with HIV/AIDS: 290,000
- Adults with HIV/AIDS: 280,000
- Rate of Adult Infection: 35.80%
- Women 15-49 with HIV/AIDS: 150,000
- Children 1-14 with HIV/AIDS: 10,000
- Orphans: 66,000

Global Burden of Disease Approach to Measuring Health Status- Caveats on Usual Stats
"In general, statistics on the health status of populations suffer from several
limitations that reduce their practical value to policy-makers:
First, they are partial and fragmented. In many countries even the most basic data—the number of deaths from particular causes each year— are not available. Even where mortality data are available, they fail to capture the impact of non-fatal outcomes of disease and injury, such as dementia or blindness, on population health.
Second, estimates of the numbers killed or affected by particular conditions or diseases may be exaggerated beyond their demographically plausible limits by well-intentioned epidemiologists who also find themselves acting as advocates for the affected populations in competition for scarce resources. If the currently available epidemiological estimates for all conditions were right, some people in a given age group or region would have to die twice over to account for all the deaths that are claimed.
- Third, traditional health statistics do not allow policy-makers to compare the relative cost-effectiveness of different interventions, such as, for example, the treatment of ischaemic heart disease versus long-term care for schizophrenia. At a time when people’s expectations of health services are growing and funds are tightly constrained, such information is essential to aid the rational allocation of resources.
The GBD set out to address these problems with three explicit aims:
- to incorporate non-fatal conditions into assessments of health status;
- to disentangle epidemiology from advocacy in order to produce objective, independent and demographically plausible assessments of the burdens of particular conditions and diseases; and
- to measure disease and injury burden in a currency that can also be used to assess the cost-effectiveness of interventions, in terms of the cost per unit of disease burden averted."
[GBD does not as yet have data on HIV/AIDS in Africa.]

Parallel Imports (PI in table on costs) - are legal imports into a country through unauthorized distributors. "Parallel importers find the national markets where goods are cheapest, and import them into countries with higher prices." Several pharmaceutical manufacturers oppose parallel imports because they set different prices for different geographic areas. Prices in the US, for example, are often higher than those for Europe, so European import-export firms could buy and then make a profit re-selling them in the US. Significance: using an example from the chart above, Spanish pharmacists could buy Clozaril from Novartis for $51.94, then sell the drug back into the US at a higher price (maybe $299), for a tidy profit.
Exhaustion of Intellectual Property Rights, also known as "The First Sale Doctrine" - Basically the doctrine says whenever a good protected by patents, copyrights, or trademarks is sold, then the owner of the goods has realized the benefits of the protection. Those rights are "exhausted" at the point of first sale. That "first purchaser" of the good is free to resell the good wherever he wishes, even if he is competing against the original producer. The exhaustion doctrine has received the blessing of the European Court of Justice (Merck v. Stephar, 1981) and the Supreme Court of Japan. The WTO rules, specifically the TRIPS accords, Article 6, permit the "exhaustion doctrine." Countries make their own laws on whether to permit parallel imports--if they do, they have ruled in favor of "Exhaustion" or "First Sale" doctrine. Pharmaceutical firms object to the Exhaustion Doctrine (and Parallel Imports), and lobby vigorously against both.
Territoriality Principle of Intellectual Property: Individuals and/or firms must obtain patent, trademark, copyright in each country of the world where they wish protection, oftentimes paying high fees to each country. Each country has its own rules granting trademark, copyright or patent laws. The argument made by some is that parallel imports violates the protection the firm or individual has obtained by registering and paying for the patent, trademark, copyright. Treaties and other international conventions have been silent on "parallel imports;" courts, both domestic and international, have supported freer trade, and not the territoriality principle for sales.
Proprietary Drugs - refers to drugs protected by patent. They can only be made by the manufacturer or a specific licensee. In the US patent protection lasts 20 years, and covers the end result; only chemical formulations (not natural products) can be patented in the US. Other countries set years, and protection differently.
- Germany, for example, permits patenting of natural herbal products. Pharmaceutical firms have rigorously tested the safety and efficacy of herbal preparations. (US pharmaceuticals and herbal firms cannot gain patent protection, thus do very little testing.)
- India has a 5 year "process" patent. If an Indian pharmaceutical firm can figure out a different way to make a drug, they can do so quite legally. The "end product" cannot gain protection, just the way it is made. Even so, five years is very short time.
Bolar Amendment - US law, recognized and accepted by the World Trade Organization, that allows manufacturers of generic drugs to prepare in advance to enter a market after a patent expires. (Of course, the Congress can extend a patent for 2 or more years.) The Bolar Amendment is seen as a minor check on the power of patent holders.
Compulsory Licensing - Governments can override patents for emergencies, or in cases of public interest or concern about anti-competition. The provision is found in Article 31 of TRIPS (International Agreement on Trade-Related Aspects of Intellectual Property Rights). The government can assign a firm a license to manufacture a drug; that firm must pay the patent-holder a royalty, and must use the drugs primarily in that country. The patent holder, of course, still retains right to manufacture and distribute.
Health Registration Data: Exclusivity for Regulatory Approval - The US regulation that permits companies who register new drugs with the FDA (Food and Drug Administration) five years of exclusive rights to use the scientific data that shows the safety and efficacy of the drug. The period of exclusivity--which ensures a monopoly for sales and clinical trials--begins with the date of drug approval by the FDA. The protection "uses regulatory barriers concerning health registration data to protect the drug from competition." Generic drugs cannot use the data developed on safety and efficacy; if they are to sell their product they must make costly independent studies. Bristol-Myers-Squibb is extraordinarily active in trying to get South Africa, Canada, Netherlands, Australia, Indonesia, Pakistan, China, Turkey, Argentina, Thailand, and other countries to adopt a similar rule; the goal is to establish an "international norm" for exclusivity for regulatory approval. Thus far, the rule applies only in the US.
Bristol Myers Squibb did not invent "Taxol" or discover its cancer-fighting attributes, so it cannot obtain a patent. The US government did so, and even sponsored and paid for the clinical data for FDA approval. Love says BMS prices Taxol "excessively" and expects sales of $1 billion in 2000. BMS charges wholesalers almost $5 per milligram; BMS acquires Taxol in bulk from a contractor such as Hauser Chemical for only $ .25 per milligram. BMS is trying to get exclusive rights to sell the drug for five years using the health registration data provision. Some call the US rule an example of "corporate welfare." Using this same rule, BSM also gained monopoly status on Vides (Didanosene-ddl) which was developed by the US National Institutes of Health, and Zerit (Stavudine-d4T) which was invented at Yale University. The latter had sales of $244 million in 1998, according to Panos. BMQ's stockholders profited by a 43% return on their shares in 1998; Love examined IRS data to show 1997 research and development costs for all drugs was only 7.4% of sales. Examples could also be given for practices of other firms.
Compulsory Licensing of Clinical Trial Data is the opposite of "Health Registration Data" provisions. The term means that when a firm develops and tests a drug, they must license others to use the data generated which shows safety and effectiveness. For example, generic manufacturers of HIV drugs would be able to obtain a license from the original manufacturer--not to make the drug, but to use the data which shows its safety and efficacy. The generic firm must show that its product is "biologically equivalent" to the approved drug. Love lobbied the South African Government to adopt this policy. (Otherwise the generic firm would have to make their own studies to generate the data, which would be very expensive.)
Donation: Manufacturers donate drug stocks for free, within the "use-by" date, on a planned, regular basis.
Import Duty: Some states fund the government through taxes on imports, which are far easier to collect than sales taxes or income taxes. (In Third World states, with low literacy, inadequate transportation and banking, many states have no income tax.) Some have suggested that import duty be eliminated for pharmaceuticals. In Zambia, for example, 5% duty is placed on imported drugs, thus driving up expensive HIV drugs even more.
Pooled Procurement/Negotiated Procurement: Several small countries negotiate as a block for bulk purchases. Ex: Caribbean.
Preferential Pricing: offer lower prices to poorer countries (higher prices in wealthy countries subsidize prices in poor countries.
Registration fees: Many states have laws requiring new drugs to be registered. In April, 2000, the cost of registration fee can be as high as $12,000.
Therapeutic Value Pricing - regulation of prices by a government-sanctioned body. (Australia: independent body sets price the government will pay for a new drug based on the therapeutic value compared to existing drugs. If substantial benefit, will set a higher price. Then government negotiates with manufacturer to get that price. If no agreement, the drug does not enter the country. If the manufacturer expects significant sales, it might accept a lower price to get the market.)
Value-Added Tax (VAT) - many countries, including France, raise money for the government by adding a tax to each stage of production--think of it as a sales tax added at each manufacturing stage and becoming part of the price. In France, 40% of the final price of most goods is the VAT. South Africa mandates a 14% VAT on both pharmaceutical drugs and condoms.
Debate: South Africa vs. Pfizer, Inc.
Below is the open, public account of the friction between South Africa's Ministry of Health and the US pharmaceutical firm, Pfizer, Inc. Students will have to use other information on this web site to develop arguments (pro and con) that can't be spoken openly because they would seem to be derogatory, insensitive, or demeaning. Neither countries nor firms can afford to insult or denigrate others. Since you are neither a government or a corporation, you can present a more thorough analysis than the "public" one given below.
Group "Pfizer" are to make a realistic argument supporting Pfizer's stance, with supportive evidence. Group "SouthAf" will make a realistic argument supporting the South African position, with explanation/evidence.
- Each group can decide how to present the data (what roles members will play).
- Each group can draw up a one-page outline (just key words) for the Document-Camera
- all letters must be at least one inch high,
- printed with a wide felt-tip (magic marker) pen (no ball points)
- Leave an inch margin (now you see why the rule is "words" not phrases!).

The Public Account of What Happened (taken from Wall St. Journal, June 21, 2000, Section B, p 1.
Pfizer, Inc. offered to give (Donation) South Africa "a powerful and expensive drug for treating a deadly AIDS-related infection." The anti-fungal drug Diflucan treats a lethal form of cryptococcal meningitis which strikes people who are HIV+, and can kill within months of the infection.
- Daily doses of Diflucan must be taken for life, and
- the daily dose is priced between $4.50 -$9 in South Africa.
AIDS activists and French based Doctors Without Borders (nonprofit NGO--Non-Governmental Organization) petitioned Pfizer in public demonstrations and letters to lower the price (Preferential Pricing). A point of interest: Pfizer's patent is not recognized in Thailand (see Proprietary), and generic manufacturers there sell their version for less than $ .60 a day. If Pfizer could not lower the price, they asked the firm to at least allow South Africa to import the drug from generic drug makers, because of the health emergency. (10% of the population, or 4.2 million are said to be infected with HIV.)
Legal counsel to South Africa's Health Minister says they may reject the offer:
- Donation is only for a period of two years; originally no time limits were indicated.
- Concern that government program--which calls for considerable time and money to set it up-- can't be sustained beyond the two years. (Pfizer's patent expires in 2 years; the gift may be an effort to instill "brand awareness" among S.A. physicians.)
- Conditions of use in South Africa set by Pfizer:
- Who can use the drug
- Only to treat meningitis (80% of infected) and not other more common fungal infections.
- Where patients must be treated
- Only for treatment in government hospitals. Why not in private hospitals, clinics?
- How patient-recipients are diagnosed
- Patients must be diagnosed by use of a spinal tap, which draws fluid from the spine. This would require special test kits and specialized physician training. Nurses, med techs, and others would not be able to take a spinal tap.
- How the drug will be distributed
- Only in South Africa's government hospitals that can certify that they cannot afford the price of the drug. Why not to private clinics and hospitals--and in extreme cases to neighboring countries?
- How the drug's use will be monitored
- Rigorous monitoring with regular reports on individuals taking the drugs to evaluate effectiveness of the drug. Is Pfizer intending to use the gift as a clinical trial in Africa, and to use results accordingly?
Pfizer replied that they
- intended to evaluate results of program in two years; if it is working the gift might be extended in South Africa and begun in other African states.
- demand a program which will ensure proper use of the drug
- many anti-fungal drugs exist, but Diflucan is the only medication that prevents death due to the life-threatening cryptococcal meningitis
- insist on measures to prevent diversion
- Monitoring with individual records, submitted regularly to Pfizer
- Tablets rather than capsules will be provided
- will not lower the price, because other countries will make similar demand
- Lower price does not mean medication will get to large numbers of people
To help Botswana cope with the AIDS problem, Bill and Melinda Gates Foundation has offered $25 million and Merck has offered free drugs. Before the money and drugs will be sent, Botswana must develop a plan for its use which needs approval of Gates/Merck.
You are the staff for the Minister of Health in Botswana, and must draw up a plan (which he will probably adopt). Obviously the plan must be acceptable to Gates/Merck as well.
Students will have to use other information on this web site to develop arguments to support your choices. While your formal report to the Minister of Defense cannot seem callous, unethical, or insensitive, you can be perfectly frank and politically realistic when explaining your choices to the Minister in person. (Click for an optional overview of Botswana. )
Group 3 - Part A: Botswana has limited medical facilities so that a great deal of the Gates money must go to renting/constructing buildings for clinics, out-patient facilities, laboratories for testing, hiring doctors, nurses, lab technicians, and training them. Includes buying generators and refrigerators, microscopes $20,000 each), etc. This is "infra-structure," How much should be spent on this infra-structure?
still Part A -A logical question: how much should be spent on
- Prevention (Educational campaigns, ads for use of condoms, purchase & distribution of condoms, infant formula for HIV+ mothers, etc.)
- Treatment and care
- HIV/AIDS
- Opportunistic Infections
- Orphanages for those whose parents have died of AIDS
How much on each main category?
Group 3 - Part A (4 members of group): Given the amount you have chosen to spend on treatment, you may be able to provide for two of these groups (both HAART and opportunistic infections; this is an ambitious program.) Which will you choose and why?
- 200 Orphans who have HIV, whose parents died of AIDS, and live in orphanages, Ages 1-15.
- 4000 Pregnant women and babies in hospitals in cities and towns (one dose at delivery for Mother and one dose for baby at 1 week)
- 400 Command Elite of Botswana (political, economic, social), treated in existing facilities, most in Gaborone.
- 300 educated, urban employed middle-class with families, treated in existing facilities (100 in Gabarone, 25 in each town)
- 250 Miners in the diamond mines (critical industry to earn foreign exchange) in new clinics at the mines
- 100 unemployed, mid-school education, who cannot afford drugs, in 5 cities, treated in new clinics (20 each in Gaborone, Tshabong, Mahalapye, Bobonong, Francistown)
- 250 Prostitutes divided among cities of Gabarone, Francistown, Tshabong, and Bobonong)

Group 3 - Part B: Two of you are the Minister of Health and have been persuaded by the recommendations given. As Minister of Health, what key arguments will you make to Gates & Merck to convince them to approve your program and start sending money? (Others in class will play the role of Gates & Merck.)
- Your group can decide how to present the data (what roles members will play).
- You can draw up a one-page outline (just key words or numbers) for the Document-Camera of your choices
- all letters must be at least one inch high,
- printed with a wide felt-tip (magic marker) pen (no ball points)
- Leave an inch margin (now you see why the rule is "words" not phrases!).
- You can use PowerPoint (Arial Bold, or Arial Black):
- print off the slide and put it on the document-cam.
- The class expects a full and frank VERBAL explanation of your choices.
