Delays in fast track antiretroviral therapy initiation and reasons for not starting treatment among eligible children in Eastern Cape, South Africa.

: We report data from an observational cohort of South African children living with HIV less than 12 years of age eligible for fast track antiretroviral therapy (rapid) initiation. We found that less than half of children eligible for rapid antiretroviral therapy initiation based on immunologic and disease status started treatment within 1 week.
