Large majorities of the public say that a variety of reasons are “major reasons” why it has been difficult to control the spread of HIV in developing countries, including widespread poverty (78%), not enough effort from the developing country governments (75%), unwillingness of people to change their unsafe sexual practices (74%), and corruption and misuse of funds (71%). Fewer than half (43%) cite not enough money from the U.S. and other developed country governments as a major reason. When forced to choose the most important reason, three in ten (30%) say unwillingness of people to change their unsafe sexual practices, and nearly a quarter (23%) say widespread poverty is the most important reason.
