Zambia has one of the highest malaria burdens in sub-Saharan Africa, with transmission occurring year-round and peaking during the rainy season from November to April. Travelers to Victoria Falls, national parks, and rural areas face the highest risk from vector-borne and waterborne diseases. Medical facilities outside Lusaka are very limited, and medical evacuation insurance is strongly advised.
