LONDON (Reuters) - HIV epidemics are becoming more concentrated in marginalised groups such as sex workers, drug users and gay men, and could defy global attempts to combat AIDS without a change in attitudes, according to a U.N. special envoy.
Michel Kazatchkine, U.N. Special Envoy for HIV/AIDS in Eastern Europe, says he would like to be able to celebrate without reservation vast global progress made in the past decade, but stubborn infection rates and alarming growth of outbreaks in hard-to-reach populations make that difficult.
