In the ETC strategy caretakers and children with HIV on ART will be supported to achieve better adherence through peer support groups at the beginning of treatment and phone follow-up later, with an option for home visits or to return to support groups later if necessary. The activities will be organized by peer supporters, caregivers of HIV-infected children selected by peers, who will undergo a series of training, including medication adherence and counselling skills. They will ideally be assigned to patients living in the same community or in proximity to patients in the intervention group.
