Adherence to malaria prophylaxis among travelers from a middle-income country

Abstract INTRODUCTION: Malaria is the main cause of death by infection among travelers and is preventable through a combination of chemoprophylaxis and personal protective measures. METHODS: Travelers were interviewed by phone 28-90 days after returning, to assess adherence to pre-travel advice for malaria prevention. RESULTS: A total 57 travelers were included. Adherence to chemoprophylaxis was significantly higher among participants prescribed mefloquine (n=18; 75%) than doxycycline (n=14; 45%). Adherence to mosquito repellent and bed net use was 65% and 67%, respectively. CONCLUSIONS: Adherence to malaria prophylaxis was lower than expected. Further studies testing innovative approaches to motivate travelers' compliance are required.

Southern African Guidelines on the Safe Use of Pre-Exposure Prophylaxis in Persons at Risk of Acquiring HIV-1 Infection

The Southern African HIV Clinicians Society published its first set of oral pre-exposure prophylaxis (PrEP) guidelines in June 2012 for men who have sex with men (MSM) who are at risk of HIV infection. With the flurry of data that has been generated in PrEP clinical research since the first guideline; it became evident that there was a need to revise and expand the PrEP guidelines with new evidence of safety and efficacy of PrEP in several populations; including MSM; transgender persons; heterosexual men and women; HIV-serodiscordant couples and people who inject drugs. This need is particularly relevant following the World Health Organization (WHO) Consolidated Treatment Guidelines released in September 2015. These guidelines advise that PrEP is a highly effective; safe; biomedical option for HIV prevention that can be incorporated with other combination prevention strategies in Southern Africa; given the high prevalence of HIV in the region. PrEP should be tailored to populations at highest risk of HIV acquisition; whilst further data from studies in the region accrue to guide optimal deployment to realise the greatest impact regionally. PrEP may be used intermittently during periods of perceived HIV acquisition risk; rather than continually and lifelong; as is the case with antiretroviral treatment. Recognition and accurate measurement of potential risk in individuals and populations also warrants discussion; but are not extensively covered in these guidelines
