Bluetongue Virus Serotype 3 and Schmallenberg Virus in Culicoides Biting Midges, Western Germany, 2023

Emerg Infect Dis. 2024 Jul;30(7):1438-1441. doi: 10.3201/eid3007.240275.

Abstract

In October 2023, bluetongue virus serotype 3 (BTV-3) emerged in Germany, where Schmallenberg virus is enzootic. We detected BTV-3 in 1 pool of Culicoides biting midges collected at the time ruminant infections were reported. Schmallenberg virus was found in many vector pools. Vector trapping and analysis could elucidate viral spread.

Keywords: BTV-3; Bluetongue virus; Culicoides; Germany; cattle; emerging diseases; livestock; midges; sheep; vector-borne infections; viruses.
