The Retrospective Implementation of Standardized In Utero HIV Exposure Definitions Using Routinely Collected Public Sector Data Across the Western Cape Province, South Africa

Abstract

Using the Data Evaluation and Preparation for HIV-Exposed Uninfected Child Cohorts project's standardized child HIV exposure definitions, 64%, 64% and 90% of children exposed to HIV in utero could be classified as HIV-uninfected with moderate or high certainty at the ages of 1 and 3 years and at the time of first infectious disease hospitalization, respectively. These definitions can be applied retrospectively to routine datasets with linked mother-child data.
