A Case of Brucellosis Concomitant with Severe Fever with Thrombocytopenia Syndrome - Weifang City, Shandong Province, China, 2023.

What is already known about this topic?:Brucellosis and severe fever with thrombocytopenia syndrome (SFTS) are neglected zoonoses, attributable respectively to Brucella and the SFTS virus (SFTSV). While the incidence of these diseases has been rising, instances of co-infection remain uncommon. What is added by this report?:This represents the first documented case of a rare coinfection involving Brucella and SFTSV. We carried out an epidemiological analysis of patients diagnosed with brucellosis and those with SFTS at Yidu Central Hospital of Weifang. Our findings demonstrate a temporal and spatial overlap among the affected individuals. What are the implications for public health practice?:Our findings suggest that co-infections arising from the spatiotemporal overlap of Brucella and SFTSV are plausible, necessitating heightened awareness and enhanced diagnostic measures.
