A tabular dataset that brings together HIV status information from two data sources: [1] a population-based HIV prevalence survey among Siaya HDSS residents performed in 2018, and [2] a surveillance of 13 public antenatal clinics (ANC) located in the HDSS area that was performance between February and November 2018. A subset of ANC records (1,122 out of 1,724 women) were individually linked to the HDSS database.
The dataset was analysed in the PLOS ONE paper “Comparison of programmatic data from antenatal clinics with population-based HIV prevalence estimates in the era of universal test and treat in western Kenya”. The study is a collaboration between the Kenya Medical Research Institute (KEMRI) and the London School of Hygiene and Tropical Medicine (ALPHA Network & MESH Network). KEMRI is the custodian of the HDSS and ANC data used in the study.
