LONDON (Reuters) - Epidemics of HIV are emerging among gay and bisexual men in the Middle East and North Africa and high levels of risky sexual behaviour threaten to spread the AIDS virus further in the region, researchers said on Tuesday.
In the first study of its kind in a region where homosexuality and bisexuality are taboo, researchers from Weill Cornell Medical College in Qatar found evidence for concentrated HIV epidemics -- where infection rates are above 5 percent in a certain population group -- in several countries such as Egypt, Sudan, Pakistan and Tunisia.
