January Series 2009: A new model for African AIDS research

from on .

The cartoon used by Epstein, author of three New York Times best-sellers, was simply a group of human stick figures connected by lines. It looked much like a family tree. It showed the inner-connectivity of a group of people through polygamous relationships. If just one member of that group decided to add a partner and that partner carried the HIV virus, the entire network could very quickly become infected. Epstein described these situations as the 鈥渙n-ramps that feed the [AIDS] superhighway.鈥

Long-term concurrency

Epstein used the Masai people from Kenya and northern Tanzania to illustrate her point. She said that in this culture, the men are polygamous and it is not uncommon for a 40-year old man to have three wives, all of progressively younger ages. A couple of those wives, however, might have a boyfriend on the side. If only one of these boyfriends has the HIV virus, everyone from within this network will become infected quite rapidly.

Promiscuity鈥揳 solution?

She suggested that the idea of serial monogamy or promiscuity鈥揾aving a succession of sexual partners鈥揵reaks up these networks, making the spread of HIV much more difficult. 鈥淣ot until these two break-up and move onto other partners can the virus spread,鈥 she said. Epstein went on to say that a group practicing 鈥榣ong-term concurrency鈥 will spread the virus 10 times faster than a group practicing 鈥榮erial monogamy.鈥 She came to these conclusions after doing extensive research beginning in the early 1990鈥檚 in Uganda.

The root of the problem

Epstein talked openly about how external solutions to the AIDS pandemic in Africa鈥揷ampaigns focused on condom use and abstinence鈥揾ave simply missed the mark. 鈥淭hey spread the same message 鈥 that AIDS is for irresponsible people, people that make mistakes.鈥 She recommends that people need to recognize the enemy is not the people with AIDS themselves, but the virus. She quoted a friend who is an AIDS worker in Tanzania: 鈥淚f people know you care for them, you can be quite open.鈥 Epstein added: 鈥淧eople can change. People change all the time, but they change in their own ways. You can鈥檛 just push a button.鈥
