For a long time heterosexuals have been told that they run significant risks of contracting HIV-AIDS if they have unprotected sex. Outside of Africa this claim is now seen to be false. Outside of Africa the main groups at risk from the disease are homosexuals, intravenous drug users and sex workers.
There will be no generalised AIDs epidemic among heterosexuals outside the African countries. AIDs still kills vast numbers of people - more than all wars and conflicts together - but expensive negative advertising campaigns directed at general populations are a waste of money.
African countries have high rates of AIDs for various reasons - low levels of male circumcision, high rates of genital herpes and high use of commercial sex workers.
