Since the Texas Animal Health Commission (TAHC) made its last vesicular stomatitis virus (VSV) update on Friday, July 12, 2019, the state has received reports of 11 new confirmed VSV cases. Equine premises with confirmed cases since July 12 include:

• Three in Bastrop County;
• One in Hays County;
• Three in Hood County;
• One in Johnson County;
• One in Shackelford County;
• One in Tom Green County; and
• One in Wichita County.

The TAHC has place the newly confirmed premises under quarantine. Regulatory and authorized veterinarians will monitor the affected horses until the premises are eligible for quarantine release 14 days after clinical VSV signs are observed.

To date, 20 premises in 12 Texas counties have confirmed cases of VSV. Of those premises, two have been released from quarantine. Currently affected counties include Bastrop, Coleman, Hays, Hood, Johnson, Shackelford, Taylor, Tom Green, Val Verde, and Wichita counties
