According to a new study, HIV/AIDS cases in London during the 1990s were in part driven by transmission of the virus within several “clusters” of people around the city, news service United Press International reports (upi.com, 3/19).

The researchers say that the HIV epidemic among men who have sex with men in London was not slow and steady, but quick and episodic within multiple clusters of men around the city.
