High Prevalence Factors • High prevalence of other STIs increase the risk of acquiring and transmitting HIV • Limited access to STI management • Limited access to, or social non-acceptance of, condoms #1-1-11
High Prevalence Factors, Cont. • War or civil disturbance • Cultural or ethnic practices, such as polygamy and wife inheritance • Women’s low status and inability to influence their partner’s behaviour #1-1-12
High Prevalence Factors, Cont. • Low literacy rates • Increasing urbanisation, migration, mobilisation and separation of families as a result of poverty or other social circumstances • Low level of political commitment to the prevention and control of HIV/AIDS • Exposure to blood from unsafe medical practices and traditional practices #1-1-13
In Summary • By the end of 2004, there were almost 40 million people living with HIV/AIDS worldwide, including more than 2 million children. • The situation is especially serious in sub-Saharan Africa, which accounts for 64% of these infections. #1-1-14
