West Nile Virus: Still A Real Threat To Equines

paulickreport.com - 08-09


West Nile virus, which is carried by mosquitoes, was first identified in 1999 and infected nearly 1,000 horses per year until 2006, when an effective vaccine was developed. In 2011, there were only 87 cases of West Nile, but the number of reported cases has been on the rise fairly rapidly, with nearly 500 cases reported in 2018. It's suspected that the actual number of cases is higher, but not all cases may be reported or a definitive diagnosis may not be reached, reported Dr. Kate Hepworth-Warren in DVM360.
