Perceived usefulness refers to the belief that a certain technology would increase an individual’s job performance. Perceived ease of use is a belief that the use of the new technology would be effortless [27].

Although 81% of persons living with HIV in sub-Saharan Africa (SSA) are now aware of their HIV status, 4.89 million remain undiagnosed, and half a million HIV-exposed infants do not receive timely early infant diagnosis each year [2-5]. Furthermore, a large share of HIV-negative adults remains unaware of being in a relationship with a person living with HIV and are therefore less likely to use effective HIV-prevention strategies [6].
