The Severe Fever with Thrombocytopenia Syndrome Bunyavirus (SFTSV) Antibody in a Highly Endemic Region from 2011 to 2013: A Comparative Serological Study

A seropositive rate of 6.59% was determined in the highly endemic region for severe fever with thrombocytopenia syndrome. A significant correlation was observed between case incidence and seroprevalence on temporal and geographic levels. Seroprevalence was comparable in the last 3 years, indicating a stable and ongoing circulation of the infection.
