The Solomon Islands have year-round mosquito activity, with peak risk during the wet season from November through April. The lowland coastal areas of the main islands, including Guadalcanal and Malaita, carry the highest risk. Interior highland areas have reduced but present exposure.
Dengue fever is a concern at moderate levels. Malaria (P. falciparum and P. vivax) remains endemic and is the most significant mosquito-borne disease. The scattered island geography means risk varies between islands, with the most populated areas having the highest burden.
Anopheles farauti is the primary malaria vector. Aedes aegypti transmits dengue. Limited healthcare infrastructure across the island chain makes prevention particularly important for travelers.
