AIDS complacency

Nature 
There is evidence that safe sexual behaviour is being eroded among gay men in some Western countries, perhaps because of complacency now that life-prolonging therapy is available. If this is the case, the complacency is misplaced. The disease remains fatal, and information from North America and Europe suggests that the decline in number of deaths due to antiretroviral therapy is tapering off.
Incidence 
A study in the US city of San Francisco showed that in 1993-1994 just over one-third of gay men reported having had unprotected anal intercourse, while the proportion of men reporting anal sex without a condom rose to one-half three years later, when effective death-postponing therapy had become available. Many of these men did not know their partners' HIV status.
Claim 
The head of a travel agency specialized in sex tourism has said that there is no need for his clients to worry about AIDS because there are a lot of researchers now who say HIV is not the cause of AIDS and HIV is not sexually transmitted.
