AIDS denialists and HIV-relevant communities in VKontakte SNS (2014)Project Head: Peter Meylakhs
The project was devoted to the representation of HIV/AIDS issue on group pages in the VKontakte SNS, with a focus on AIDS-denialaist movement communities. This movement based in the denial of the existence of HIV or of AIDS, or of their connection presents a serious problem for the public health. Influence of AIDS-denialists leads to refusal of a part of population from testing for HIV and / or from HIV treatment. This contributes to higher mortality from AIDS and HIV-related diseases, and further spread of HIV among the populace. Therefore, an important research goal is to see how AIDS-denialists disseminate their views on the Internet and how they are positioned among other HIV-relevant groups.
