CountryLao People's Democratic Republic

Lao People’s Democratic Republic (PDR) has made significant advances in malaria control, with a 50% reduction in malaria cases between 2000 and 2011 and a 93% reduction in malaria deaths between 2000 and 2010. Malaria transmission is concentrated in remote, forested regions in the south of the country, and peaks during the hot and rainy season between May and October. Six southernmost provinces – Saravane, Champasack, Savannakhet, Khammouane, Attapeu,and Sekong – accounted for 96 percent of reported cases in 2014. Four vectors are responsible for malaria transmission in the country: Anopheles dirus, An. minimus, An. maculatus, and An. jeyporiensis.

Recent malaria resurgence and antimalarial drug resistance have threatened progress towards national elimination targets, with artemisinin-resistant Plasmodium falciparum detected in Champasack and Attapeu provincesForeign investment in mining, hydropower, and agriculture projects in the southern provinces, and the subsequent influx of mobile migrant populations, are suspected of contributing to a resurgence in 2012. Other high-risk populations include traditional farming communities, ethnic minorities, forest and wildlife protection services, and military forces deployed at country borders. Despite the recent outbreaks in the south, the country's remaining twelve provinces continue to make rapid progress towards sub-national elimination goals.
