Background: Early infant diagnosis (EID) is critical for timely identification and treatment of children living with HIV. However, in 2024, EID cascade indicators were suboptimal with only 27% and 22% of HIV-Exposed Infants (HEI) receiving their first and second virologic test within two and 12 months respectively, in Cameroon’s Littoral and South regions. We share the experience of a program optimization approach (POA) implemented to improve EID coverage in these regions.

 

Description: We analyzed cross-sectional routine program data from December 2024 to March 2025, during implementation of the POA in 75 facilities. The POA started with brainstorming sessions involving multidisciplinary teams to conduct root cause analysis of suboptimal EID coverage and identify areas of improvement and select appropriate interventions. The intervention package included line listing of HEI born between October 2022 and September 2024 from the national HIV program database, verification against facility cohort monitoring registers and patient files, active tracking of those eligible through phone calls and home visits, close monitoring of the coverage catch-up (real-time dashboard and regular supervision). Changes in EID cascade indicators were measured throughout the POA implementation.

 

Lessons Learned: A total of 3,491 HEI were identified at participating facilities; 2,845 (82%) were eligible for tracking and 1,975/2,845 (69%) were successfully tracked by March 2025. Completion of age-appropriate HIV virologic and serologic testing increased from 31%(1,079/3,491) to 69% (2,402/3,491) post implementation. Antiretroviral therapy initiation among infants with a positive virologic or serologic result improved from 68% (28/41) to 78% (32/41). The proportion of HEI eligible for a serologic test with a documented final HIV outcome increased from 17% (314/1,828) to 84% (1,534/1,828).

 

Next Steps: EID cascade indicators were higher following the completion of the POA intervention package activities, but substantial gaps remain. This underlines the importance of continuous monitoring to strengthen implementation process and outcomes.
