The Philippines has year-round mosquito activity, with peak season during the southwest monsoon from June through November. Metro Manila, the Visayas, and Mindanao experience the highest dengue burden. Rural and forested areas, especially on Palawan and Mindanao, carry additional malaria risk.
Dengue fever is the leading mosquito-borne disease and a major public health concern, with recurrent large outbreaks. Malaria (P. vivax) persists in remote forested provinces. Chikungunya, Zika, Japanese encephalitis, and lymphatic filariasis are also present in the country.
Aedes aegypti and Aedes albopictus are the primary day-biting vectors in urban and suburban environments. Anopheles species transmit malaria in forested and rural areas, biting primarily from dusk to dawn.
