No indigenous cases were reported as of September 2020. 4 The monthly data for 2020 reported under Myanmar is not final and may be subject to change. 5 Malaria deaths of Thailand are officially reported annually. Monthly malaria cases and deaths by country in 2020 (January–March) Data sources: Reported cases include cases reported from all sources of public health facilities, community health workers and the private sector. For the regional map of malaria incidence by province, the annual population estimate is based on the estimate submitted by each country to the World Malaria Report in 2018. All other population estimates are based on the annual UN estimate of total population.
