Background:  Most HIV-infected children in Africa present with severe symptoms and die before they have the chance to start ART, or even cotrimoxazole prophylaxis. Recent changes to WHO guidelines for the treatment of HIV-infected children are founded on evidence that early initiation of antiretroviral therapy significantly improves survival. It is difficult however, to reconcile this recommendation with the experience reported by many prevention of mother-to-child transmission of HIV (PMTCT) programs that postnatal HIV testing of infants is relatively uncommon and early identification of infected children is difficult.

Methods:  Routine HIV testing of infants was offered to all mothers bringing infants for immunizations at 3 clinics in KwaZulu Natal. Blood samples were collected by heel prick onto filter paper. Dried blood spots were tested for HIV antibodies and if present, were tested for HIV DNA by PCR. Exit interviews were requested of all mothers irrespective of whether they had agreed to infant testing or not.

Results:  Of 646 mothers bringing infants for immunizations, 584 (90.4%) agreed to HIV testing of their infant and 332 (56.8%) subsequently returned for results. Of 646mothers and infants, 332 (51.4%) thereby had their HIV status confirmed or reaffirmed by the time the infant was 3 months of age. Overall, 247 of 584 (42.3%) infant dried blood spot samples had HIV antibodies indicating maternal HIV status. Of these, 54 (21.9%) samples were positive for HIV DNA by PCR. This equates to 9.2% (54/584) of all infants tested. The majority of mothers interviewed said they were comfortable with testing of their infant at immunization clinics and would recommend it to others.

Conclusions:  Screening of all infants at immunization clinics is acceptable and feasible as a means for early identification of HIV-infected infants and referral for antiretroviral therapy. Implications for primary health care systems and related services such as confidentiality of results and counseling on infant feeding need to be considered before implementing.
