Knowledge of transmission of HIV/AIDS

Situation

Women: The percentage of women with correct knowledge about sexual transmission of HIV/AIDS in urban areas is at least 80% even among the poorest 20% population in all regions, except in Asia where only 56% of the poorest 20% urban women have the correct knowledge. The gap in knowledge between the richest 20% and poorest 20% urban women is also greatest in Asia.

Men: The percentage of men with correct knowledge about sexual transmission of HIV/AIDS is 90% or higher in urban areas, even among the poorest 20%, in all regions except in Asia. In general, the richest 20% men tend to be more knowledgeable than the poorest 20% men in urban areas, with the gap being the widest in Asia.


Trends

Women: Knowledge about sexual transmission of HIV/AIDS has improved since the 1990–1999, especially among the poorest urban women. The correct knowledge of sexual transmission of HIV/AIDS increased for the poorest 20% urban women in Africa, Americas and Asia by 32%, 19% and 31%, respectively, between 1990–1999 and 2000–2011. Inequalities between the richest 20% and poorest 20% urban women have also decreased in these regions over the same time period.

Men: Knowledge of sexual transmission of HIV/AIDS has improved among urban men since 1990–1999, especially in Africa where 90% of even the poorest 20% urban men had the correct knowledge when measured in 2000–2011. On average, the correct knowledge of sexual transmission of HIV/AIDS increased for the poorest 20% urban men in Africa, Americas and Asia by 30%, 8% and 68%, respectively, between the 1990–1999 and 2000–2011.
