This study mainly based on the secondary data. The study reveals that wide socio-demographic disparities in knowledge about HIV/AIDS within the population indicate that the level of HIV/AIDS knowledge might be much lower among some vulnerable populations (women, youth and unmarried persons) and those with low levels of education and media exposure. Media exposure has a statistically significant positive influence on correct knowledge of AIDS transmission and prevention, net of educational and occupational effects. TV was the most dominant media exposure than radio and news paper exposure. The most frequently routes of HIV/AIDS transmission was through unsafe blood transfusion. The correct knowledge of ways of prevention of HIV/AIDS was use of condoms during intercourse (51% urban population believes) and abstaining from sexual intercourse (51% rural population believes). Multivariate logistic analysis revealed that urban married women more likely to use knowledge about HIV/AIDS than rural married women.
