West Nile Virus: Threat and Response

West Nile virus struck fear into horse owners when it quickly became clear that equines were more vulnerable to the virus than humans. In 1999, one in three equines that contracted WNV in North America died, while most survivors were left with neurologic problems. It could have been prevented with vaccinations, but management beyond vaccination is important.
Although vaccination has decreased the incidence of WNV in horses, the infection rate in mosquitoes is still high. That means the virus remains active in the reservoir population – it’s just not as prevalent in horses at the moment.
So much about the behavior of WNV remains unexplained, including how it spread in the first place. This free report provides the horse owner and caretaker with an overview of WNV and how to prevent
