Public Health Strategies: Containing the Epidemic

Targeting core transmitters to contain the epidemic diagram

Slide 14

One element of a public health strategy is the targeting of core transmitters for large-scale STD prevention and treatment services.

An STD/HIV control program in Kenya targeted 500 sex workers, 80 percent of whom were HIV-infected. The workers, estimated to have an average of four clients per day, were assessed for other STDs and treated when such STDs were present. They also received STD/HIV counseling and free condoms, and were counseled to use condoms with their clients. The sex workers subsequently reported using condoms in 80 percent of sexual contacts. It was estimated that as many as 10,200 new HIV infections of clients and client partners may have been prevented annually as a result of this intervention.

Theoretically, if the program had targeted 500 men chosen at random from the low-income community in which the sex workers worked, only 88 new HIV infections per year would have been avoided, even if the men also raised their condom use to 80 percent. This is because only about 10 percent of the male population was infected with HIV and the average man had four partners per year.
