On April 13, 2020, the National Veterinary Services Laboratories (NVSL) in Ames, Iowa, confirmed a finding of vesicular stomatitis virus (VSV) infection (Indiana serotype) on an equine premises in Dona Ana County, New Mexico.  A single horse on the index premises has met the case definition of infection with compatible clinical signs and virus isolation positive results. A second equine premises in Sierra County, New Mexico subsequently met confirmed VSV case definition with compatible clinical signs and reverse transcription-polymerase chain reaction (RT-PCR)-positive results for VSV (Indiana serotype).  This is the 2020 VSV index case for the United States and subsequent VSV case for New Mexico. ***UPDATE: Bernalillo, De Baca, and Grant counties have also confirmed cases for VSV***

The epidemiological investigations on both VSV-positive premises indicate that incursion of VSV-infected insect vectors is the likely source of infection in these herds.  Biosecurity measures and vector mitigation have been instituted to reduce spread of the virus.
