Eritrea has seasonal mosquito activity, with peak risk during and after the rains from June through September. The western lowlands, the Gash-Barka region, and areas below 2,000 meters carry the highest malaria burden. The highland capital Asmara has minimal risk. The Red Sea coastal strip has year-round low-level activity.
Malaria (P. falciparum and P. vivax) is the primary concern, with the western lowlands being the main transmission zone. The country has achieved significant reductions in recent years through bed net distribution and spraying campaigns.
Anopheles gambiae is the primary malaria vector in the western lowlands. The altitudinal range creates a clear division between the malaria-free highlands and the endemic lowlands.
