Socio-demographic factors are also important to determine the knowledge about HIV prevalence and transmission. The current study has used the Multiple Indicator Cluster Survey 2011 to estimate the impact of sociodemographic factors to determine the knowledge about HIV. Age and wealth index showed highly significant relationship (p<0.0000) in determining the knowledge of HIV. Similarly, the people belonging to the “Rich” group as compared to the “poor” had high percentage for the spread of HIV and, likewise, the misconception of the rich about the spread of HIV was low as compared to the poor and vice versa. Moreover, the increasing level of education showed a decreasing trend of misconception about the spread of HIV.
