Misconceptions about HIV transmission, stigma and willingness to take sexual risks in southwestern China.

Based on data from a population-based survey conducted in 2003 in a province in southwestern China, we provide data on knowledge about HIV transmission, HIV stigmatizing attitudes, and willingness to take HIV-related risks. There were widespread misconceptions, especially among females, about how HIV is transmitted and negative feelings toward someone with HIV. There was considerable willingness to take more sexual risks (not using a condom; nondisclosure of HIV seropositive status) with a secondary than with a primary sexual partner. The misconceptions and stigma surrounding HIV may make it difficult to focus on HIV as a 'disease' as opposed to a 'social malady' for survey participants.
