The Philippines is a densely populated archipelago of more than 7,000 islands, and is working to eliminate malaria subnationally, province by province. Reported malaria cases in the country declined from 6,514 to 4,903 cases between 2000 and 2014; deaths due to malaria declined by 98%, from 536 to only 10 deaths. The majority (81%) of reported cases in 2014 were due to Plasmodium falciparum, and 17% were due to P. vivax; P. malariae and P. knowlesi accounted for less than 1% of infections. Malaria transmission occurs year-round but is typically higher during the rainy season, peaking during July through September.
The primary vector is Anopheles flavirostris, which breeds in clear, slow-flowing streams in foothills and in rice paddies. Secondary vectors include An. maculatus, An. litoralis, and An. balabacensis. The highest transmission occurs in the provinces of Palawan, Tawi-Tawi, Sulu, and Maguindanao. High risk groups include forest workers, subsistence farmers, and indigenous peoples.
- 61% of the total population at risk (total population: 99.1 million)
- 4,903 confirmed cases of malaria and 10 deaths in 2014
- 0.05 Annual Parasite Index (cases/1,000 population/year)
- Dominant malaria species: P. falciparum (81%)
- Elimination goal: zero indigenous cases and zero deaths by 2030
