: This study received ethical approval from the Institutional Review Board of IHI and National Institute for Medical Research Tanzania (NIMR/HQ/R.8a/Vol.IX/3222). Written informed consent was obtained from all study participants prior to commencement of the study. The participants were males only and reason include: it is not culturally acceptable for women to be out late at night wearing shorts with other men around them. Also, women of working age in the settings where the study was conducted are usually married/mothers/of child bearing age. For them to be included we would need to ask them questions on their birth control/pregnancy status which some might not be comfortable sharing thus limiting their participation. All study volunteers were provided with Doxycycline<sup>®</sup> malaria prophylaxis and tested weekly for malaria infection using malaria rapid diagnostic tests administered by a medical officer. No volunteers tested positive for malaria throughout the duration of this study. No adverse effects were reported among the volunteers throughout the duration of the study.
