Bluetongue virus (BTV) is a dsRNA virus of the genus Orbivirus . The virus causes bluetongue disease. [1] [2] [3] BTV is relatively fragile and its infectivity is lost in slightly acidic environments.
The recently spreading BTV-3 variant (BTV-3/NET2023) has raised concerns due to its fast spread in Europe, and the introduction of this variant could pose new challenges for disease control. [4] In response to this, several countries have implemented vaccination campaigns, but the challenge lies in matching vaccines to the circulating strain. The BTV-3 variant’s genetic stability has been confirmed through sequencing, and vaccines currently in use are expected to be effective against it. [5] [6]
