Jubilee M, et al. - In view of the incredibly high HIV burden in Lesotho despite years of HIV testing and other interventions, Population Services International (PSI)/Lesotho with support from the Centers for Disease Control and Prevention (CDC) introduced the HIV Index testing model in 2015, in order to identify adults, adolescents and children at high risk of HIV infection. Through health facilities and community testing at PSI New Start channels in five districts, PLHIV recruited for index testing were accessed. Home visits were provided to consenting index clients for HIV testing of their biological children and sexual partners with unknown status. Researchers performed an analysis of routine monitoring of data gathered between May 2015 and November 2017 to assess the workability of this approach. Results support that to identify and link children, adolescents and adults into care and treatment, testing of biological children and sexual partners utilizing the HIV index testing model is viable.
