Liberia has year-round mosquito activity in its equatorial climate, with peak risk during the rainy season from May through October. The entire country carries high malaria burden, with the coastal lowlands, Monrovia, and rural areas all significantly affected.
Malaria (P. falciparum and P. vivax) is the primary concern and among the leading causes of death. Yellow fever is endemic. Limited health infrastructure and post-conflict recovery challenges complicate disease control.
Anopheles gambiae is the dominant malaria vector. Aedes aegypti transmits yellow fever. The hot, humid equatorial climate and abundant rainfall maintain high mosquito density year-round.
