HIV self-testing services for female sex workers, Malawi and Zimbabwe.

Objective: To present findings from implementation and scale-up of human immunodeficiency virus (HIV) self-testing programmes for female sex workers in Malawi and Zimbabwe, 2013-2018.

Methods: In Zimbabwe, we carried out formative research to assess the acceptability and accuracy of HIV self-testing. During implementation we evaluated sex workers' preferences for, and feasibility of, distribution of test kits before the programme was scaled-up.

'Whose failure counts?' A critical reflection on definitions of failure for community health volunteers providing HIV self-testing in a community-based HIV/TB intervention study in urban Malawi.

The category of community health worker applied within the context of health intervention trials has been promoted as a cost-effective approach to meeting study objectives across large populations, relying on the promotion of the concept of 'community belonging' to encourage altruistic volunteerism from community members to promote health. This community-based category of individuals is recruited to facilitate externally driven priorities defined by large research teams, outside of the target research environment. An externally defined intervention is then 'brought to' the community through locally recruited community volunteers who form a bridge between the researchers and participants.
