Perceived barriers and facilitators in using text and voice messaging for improving HIV and sexual and reproductive health of female entertainment workers in Cambodia: a qualitative study.

Background: Female entertainment workers (FEWs) in Cambodia are one of the hard-to-reach populations at risk of human immunodeficiency virus (HIV) and poor sexual and reproductive health (SRH). Due to the stigmatizing nature of their work, it is difficult to reach them with prevention and treatment services. The Mobile Link project is a mobile health (mHealth) intervention that aims to deliver health messages to FEWs and link them up to health services.
