We examined HIV-1 resistance in children failing first-line and second-line antiretroviral therapy in South Africa, all with clade C virus. Those exposed to full-dose ritonavir had multiple protease resistance mutations. Nineteen percent had wild-type virus. Appropriate antiretroviral therapy sequencing in sub-Saharan African children is essential for prolong treatment options.
