The key discovery, researchers say, is the power of AIDS medicines in combination. Separately, these drugs have not been successful in combating AIDS; together, they have been found to be much more effective. The combination of drugs seems to be able to stop the HIV virus from reproducing, meaning that it cannot destroy the immune system. The result is the prospect that AIDS will become a manageable disease - an illness that can be kept in check with lifelong treatment.
There are, to be sure, reservations. Scientists warn that the virus might develop resistance to the drug combination. And the treatment is very expensive - up to $13,000 a year for each patient. Only wealthy countries could conceivably afford such an expense. In the poor regions of Africa, Asia and Latin America where AIDS is raging, the cost is out of the question.
In time, the cost could come down. Other medications that were once prohibitively expensive have had their cost reduced sharply as a result of production in volume and improved methods. But that hope will not save the millions of people in Third World countries who are already infected.
The immediate need is for more education on preventive methods, particularly the use of condoms. At the Vancouver meeting evidence was presented that messages on prevention can be effective. In Thailand, for example, HIV infections are running at a quarter of the 1990 rate. The developed countries should support AIDS education in the poorer countries as well as their own. They should also assist in providing cheap drugs to treat the illnesses that often accompany AIDS and are the immediate cause of death, particularly tuberculosis.
Powell says he is a Republican, but if he is not willing to speak at the Republican convention or work for the party's candidates, what use is he? His unwillingness to take an active role in the campaign may be resented. This decision could hurt him if he decides to be a candidate in a future election.
