THERE are some 33m people living with HIV in the world today, estimates UNAIDS, the United Nations agency charged with combating the disease and supporting the rights of those affected. Travel restrictions are one type of discrimination these people can face. In the past year, both China and America have lifted 20-odd-year bans stopping individuals with HIV from entering, but 51 countries still restrict movement in some form (be it entry to the country or a stay therein) based on a person's HIV status. Our tables show those countries applying the severest restrictions to HIV sufferers, including the denial of entry visas and even deportation. Many countries in the Middle East impose strict restrictions—and also report among the lowest HIV prevalence rates.
