Myanmar experiences peak mosquito activity during the monsoon season from May through October, when heavy rainfall creates extensive breeding habitat. The border regions with Thailand, China, India, and Bangladesh, along with forested highland areas, carry the highest risk. Urban areas like Yangon and Mandalay also see significant dengue activity.
Dengue fever is the primary concern in urban and peri-urban areas. Malaria (P. falciparum and P. vivax) remains a major concern in forested and border regions, though national cases have declined. Chikungunya, Zika, Japanese encephalitis, and lymphatic filariasis are also present.
Aedes aegypti drives dengue transmission in cities, while Anopheles dirus and Anopheles minimus are the primary malaria vectors in forested and hilly areas. Culex species also circulate, linked to Japanese encephalitis near agricultural zones.
