Early mortality and loss to follow-up in HIV-infected children starting antiretroviral therapy in Southern Africa
Background: Many HIV-infected children in Southern Africa have been started on antiretroviral therapy (ART), but loss to follow up (LTFU) can be substantial. We analyzed mortality in children retained in care and in all ...
Virologic failure and second-line antiretroviral therapy in children in South Africa-the IeDEA Southern Africa collaboration
