Forty per cent of the global population at risk of malaria live in the South-East Asia Region-- home to a quarter of the world's population.
Malaria is endemic in 10 of the 11 countries of the Region which includes India, Bangladesh, Bhutan, Democratic People's Republic of Korea, Indonesia, Myanmar, Nepal, Sri Lanka, Thailand and Timor-Leste.
Maldives is the only country in the Region that has remained free of malaria (malaria-free since 1984).
Sri Lanka made remarkable progress in controlling malaria by bringing cases down from 203,000 in 2000 to zero locally acquired malaria cases since November 2012, WHO said.

"Countries must prioritize vector-borne diseases in their national development agendas. Communities need to be empowered to fight this battle and protect themselves. Preventing and controlling vector-borne diseases is everyone's responsibility," she said.
