Background: Human Immunodeficiency Virus (HIV) infection among children is mainly vectored through mother-to-child transmission. Prevention of mother-to-child-transmission strategy is highly effective; however, its accessibility and utilization is affected by the lack of knowledge among other factors.

A significant proportion of HIV-positive women compared to HIV-negative women were aware that correct use of antiretroviral during pregnancy can reduce the risk of mother-to-child-transmission of HIV (p
