Characterizing mobility patterns of forest goers in southern Lao PDR using GPS loggers
Abstract Background In the Greater Mekong Subregion (GMS), forest-going populations are considered high-risk populations for malaria and are increasingly targeted by national control programmes’ elimination efforts. A better understanding of forest-going populations’ mobility patterns and risk assoc...
