Shrinking the Malaria Map

UCSF Global Health Group’s Malaria Elimination Initiative (MEI)

Thailand

Thailand has been pursuing spatially progressive elimination and has a national goal to eliminate malaria by 2024.

Thailand experienced a 52% decrease in reported malaria cases between 2000 and 2014, from 78,561 cases to 37,921 cases. In 2011, 50% of the population in Thailand was living in malaria-free areas. Thirty-five percent of cases in 2011 were due to Plasmodium vivax. Thailand has two transmission peaks—June to August and October to November— when its rainy season leads to an increase in breeding by the primary vector. Central Thailand has been malaria-free for more than three decades. However, malaria-endemic areas are located along the forested borders with Myanmar to the west and Cambodia to the east. The border area between Cambodia and Thailand has been the epicenter of malaria drug resistance since 1960, and a high level of population movement along border areas has exacerbated the recent spread of multidrug resistant P. falciparum.

Intensive vector control measures, such as indoor residual spraying (IRS) with DDT and improved access to personal protection measures, have resulted in a marked reduction in malaria incidence. The national malaria control program, with support from the Global Fund to fight AIDs, Tuberculosis, and Malaria and the U.S. President’s Malaria Initiative, is working to reduce malaria along border regions through these vector control measures by targeting at-risk populations. Thailand is a country partner in the Asia Pacific Malaria Elimination Network (APMEN).
