BACKGROUND Population movements following disasters can cause important increases in morbidity and mortality. Without knowledge of the locations of affected people, relief assistance is compromised. No rapid and accurate method exists to track population movements after disasters. We used position data of subscriber identity module (SIM) cards from the(More)

BACKGROUND Among people living with HIV (PLHIV) on antiretroviral therapy (ART), it is important to determine how quality of life (QOL) may be improved and HIV-related stigma can be lessened over time. This study assessed the effect of peer support on QOL and internal stigma during the first year after initiating ART among a cohort of PLHIV in north-eastern(More)
Researchers in many scientific fields make inferences from individuals to larger groups. For many groups however, there is no list of members from which to take a random sample. Respondent-driven sampling (RDS) is a relatively new sampling methodology that circumvents this difficulty by using the social networks of the groups under study. The RDS method has(More)
OBJECTIVES Survey data from men who have sex with men (MSM) in Asian cities indicate ongoing and drastic increases in HIV prevalence. It is unknown which behavioural factors are most important in driving these epidemics. We aimed to analyse detailed sexual behaviour data among MSM in Vietnam and to model HIV transmission using improved assumptions on sexual(More)
SETTING Better integration of treatment support for people living with tuberculosis (TB) and human immuno-deficiency virus/acquired immune-deficiency syndrome (HIV/AIDS) is a challenge in many settings, and has been identified as a service priority. OBJECTIVE To determine the impact, compared to directly observed therapy, of a TB treatment intervention(More)
