Abstract
OBJECTIVES
Few routine systems exist to test older, asymptomatic children for HIV. Testing all children in the population has high uptake but is inefficient, whereas testing only symptomatic children increases efficiency but misses opportunities to optimize outcomes. Testing children of HIV-infected adults in care may efficiently identify previously undiagnosed HIV-infected children before symptomatic disease.

METHODS
HIV-infected parents in HIV care in Nairobi, Kenya were systematically asked about their children’s HIV status and testing history. Adults with untested children ≤12 years old were actively referred and offered the choice of pediatric HIV testing at home or clinic. Testing uptake and HIV prevalence were determined, as were bottlenecks in pediatric HIV testing cascade.

RESULTS
Of 10,426 HIV-infected adults interviewed, 8,287 reported having children, of whom 3,477 (42%) had children of unknown HIV status, and 611 (7%) had children ≤12 years of unknown HIV status. After implementation of active referral, the rate of pediatric HIV testing increased 3.8-fold from 3.5 to 13.6 children tested per month (Relative risk: 3.8, 95% confidence interval: 2.3 to 6.1). Of 611 eligible adults, 279 (48%) accepted referral and were screened, and 74 (14%) adults completed testing of 1 or more children. HIV prevalence among 108 tested children was 7.4% (95% confidence interval: 3.3 to 14.1%) and median age was 8 years (interquartile range: 2-11); 1 child was symptomatic at testing.

CONCLUSIONS
Referring HIV-infected parents in care to have their children tested revealed many untested children and significantly increased the rate of pediatric testing; prevalence of HIV was high. However, despite increases in pediatric testing, most adults did not complete testing of their children.
