When people are exposed to HIV-positive infectious bodily fluids either through skin puncture, contact with mucous membranes or contact with damaged skin, they are at risk for acquiring HIV. Pooled estimates give a risk of transmission with puncture exposures of 0.3% [115] and mucous membrane exposures 0.63%. [116]
Populations who access HIV testing are less likely to engage in behaviors with high risk of contracting HIV, [16] so HIV testing is almost always a part of any strategy to encourage people to change their behaviors to become less likely to contract HIV. Over 60 countries impose some form of travel restriction, either for short or long-term ...
