Making sense of sexual risk-taking by gay men
Psychological knowledge and understanding can help make sense of recent reports of an increase in unprotected anal intercourse (termed ‘barebacking’) among gay men.

Fran'§oise Hamers and Angela Downs describe recent trends in the HIV... view more... (2003-03-20)
State laws may limit implementation of CDC's recommendations for routine HIV testing

If started early, HIV treatment reduces death rates toward background levels in African countries
Mortality rates of people starting HIV treatment in four African countries approach those of the general population over time, provided that treatment is started before the immune system has been severely damaged, according to research published this week in the open-access journal PLoS Medicine. view more (2009-04-28)
Are HIV Infection And Personality Linked?
Currently, HIV is one of the most widely spread epidemics in the world. The specificity of the mode of transmission, the well-known severity of the prognosis, and the kind of therapies used are peculiarities of this illness. Personality traits of individuals with HIV may influence conditions for the infection itself. On the other hand, it is... view more... (2004-11-18)
AFRICAN HIV-1 EPIDEMIC NOT CAUSED BY MORE INFECTIOUS VIRAL SUBTYPE (p 1149)
The explosive HIV-1 epidemic in sub-Saharan Africa is unlikely to be the result of a viral subtype with increased infectivity, according to the results of a study published in this week’s issue of THE LANCET. The HIV-1 epidemic in eastern and southern sub-Saharan Africa is mainly caused by HIV-1 subtypes A, C, and D, whereas those in the USA... view more... (2001-04-11)
