Timor-Leste has peak mosquito activity during the wet season from November through May. The northern coastal lowlands and the Dili district carry the highest risk, while mountainous interior areas have somewhat reduced exposure.

Dengue fever is a primary concern, with moderate activity reported. Malaria (P. falciparum and P. vivax) remains present, particularly in rural and lowland areas, though cases have declined with control efforts. Japanese encephalitis and lymphatic filariasis are also present.

Aedes aegypti transmits dengue in urban areas during the day, while Anopheles species carry malaria in rural settings, biting at night. Limited healthcare infrastructure in remote areas increases vulnerability for rural residents and travelers.
