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 provinces. Foreign 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.
- 93% of the total population are at risk (total population: 6.7 million)
- 48,071 cases of malaria and 4 deaths in 2014
- 7 Annual Parasite Index (cases/1,000 population/year)
- Dominant malaria species: P. falciparum (62% of cases)
- Elimination goal: zero indigenous cases and zero deaths by 2030
