    Series Information

    The ALPHA (Analysing Longitudinal Population-based HIV/AIDS Data in Africa) Network is a collaboration among 10 longitudinal studies in sub-Saharan Africa. These studies collect data on HIV infection alongside demographic, behavioural, socio-economic and clinical data from residents of the study areas. The Network harmonises these data and conducts comparable and pooled analyses on HIV-related research questions.The ALPHA HIV Incidence and Mortality data, Manicaland is part of the international data harmonisation and analysis programme of the ALPHA network.

    Abstract

    The Manicaland dataset is created from harmonising longitudinal population-based demographic surveillance and repeated serological survey data collected by an Open Population Cohort Study in Manicaland, Zimbabwe. The data harmonisation is coordinated by the ALPHA Network which curates individual-level data on demographic surveillance, verbal autopsy interviews, serological and sexual behaviour surveys, and individually-linked data from HDSS and medical facilities.

    The data from the Manicaland site in Zimbabwe is provided in two data files:
    HIV incidence data:
    This file includes data on resident study participants aged 15-49 who have had one negative HIV test and at least one subsequent HIV test done within the study for research purposes. Data may be split into multiple observations for each person to describe time spent in different residencies, different age groups and different calendar year periods.All timings are given as age at event, instead of the dates. Dates of birth were rounded to the 15th of the month, and all other dates were offset by the same amount and the time elapsed between the rounded dates is used as the age at event.
    To enable multiple imputation of seroconversion dates the times (ages) of last negative test and first positive test have been provided
    Mortality data:
    This data file was created as described here https://gatesopenresearch.org/articles/1-4
