Index-linked Assisted HIV Self-Testing for Children 2-14 Years: Results of a Pilot Evaluation in Ethiopia.

Background: Case identification remains a challenge to reaching the United Nations 95-95-95 targets for children with HIV. While the World Health Organization approved oral mucosal HIV self-testing (HIVST) for children over 2 years in 2019, there is little information on HIVST for pediatric case identification in Ethiopia.

Setting: Nine health facilities across Ethiopia.

Methods: We implemented a pilot program from November 2021-April 2022 to assess acceptability and feasibility of using HIVST to screen children 2-14 years of adult index clients, (i.e., parents/caregivers living with HIV and on antiretroviral therapy). HIV-positive adults who had children with unknown HIV status were given HIVST kits (OraQuick®) to screen their children at home. Parents/caregivers were asked to report results telephonically and bring children screening positive to the health facility for confirmatory HIV testing. We defined HIVST acceptability as ≥50% of parents/caregivers accepting testing and ≥50% reporting results within seven days of receiving a test kit. Feasibility was defined as ≥60% of children with a reactive HIVST receiving confirmatory testing and <5 serious social harms reported per 1000 kits distributed.

Results: Overall, 1496 of 1651 (91%) parents/caregivers accepted HIVST kits to test their children at home and 1204 (71%) reported results within seven days. Of 17 children (1%) with reactive results, 13 (76%) received confirmatory testing; of which 7 (54%) were confirmed to be HIV-positive. One serious social harm was reported.

Conclusion: Providing adult parents/caregivers with HIVST kits to screen their children at home is an acceptable and feasible strategy to reach untested children and improve pediatric case finding in a low prevalence setting.
