Scientists in a policy paper in PLoS Medicine suggest that the internet has become a fertile ground for spreading false information by the HIV denialists.
False information about HIV/AIDS spread online can have serious consequences to public health. HIV denialist organizations such as "Reappraising AIDS" have become more aggressive in their campaign in denying the disease and spreading false in formation. Tara Smith (University of Iowa College of Public Health) and Steven Novella (Yale University School of Medicine) believe that "It may seem remarkable that, 23 years after the identification of HIV, there is still denial that the virus is the cause of AIDS."
There is a consensus in the scientific community that HIV is the cause of AIDS, based upon over two decades of robust research. Deniers must therefore reject this consensus, say Smith and Novella, "either by denigrating the notion of scientific authority in general, or by arguing that the mainstream HIV community is intellectually compromised."
Many members of the general public do not have the scientific background to critique the assertions put forth by these groups, say Smith and Novella. Those who believe the false information spread by HIV denialists could end up putting themselves at risk of HIV infection (e.g. by abandoning safe sex), while those who are already infected could end up seeking unproven, ineffective remedies.
"The effect of denial groups on public perception of HIV infection is an area ripe for careful research," they say "as this denial can have lethal consequences."
