As the old killer makes a comeback, the World Health Organization is urging precautionary measures for one group in particular: men who have sex with men.
"We are seeing exploding epidemics," said Gottfried Hirnschall, head of WHO's HIV department.

Men who have sex with men are 19 times more likely to be infected with HIV than the general population, Hirnschall noted.
As the AFP reported:
In its new recommendations for combatting the HIV/AIDS pandemic, published Friday, the UN health agency therefore for the first time "strongly recommends men who have sex with men consider taking antiretroviral medicines as an additional method of preventing HIV infection".
US authorities made the same recommendation in May.
Taking pre-exposure prophylaxis medication, for instance as a single daily pill combining two antiretrovirals, in addition to using condoms, has been estimated to cut HIV incidence among such men by 20-25 percent, WHO said, stressing that this could avert "up to one million new infections among this group over 10 years".
The new guidelines also focus on other high-risk groups, pointing out that men who have sex with men, transgender people, prisoners, people who inject drugs and sex workers together account for about half of all new HIV infections worldwide.
