We evaluated human Crimean-Congo hemorrhagic fever virus (CCHFV) seroprevalence in hunter-gatherer populations of northeastern Democratic Republic of the Congo. We tested blood from 300 participants for CCHFV antibodies; 4% were CCHFV-positive. CCHFV likely has been circulating undetected in the country, indicating the need for a more robust surveillance system.
