West Nile Virus

How Can I Protect Myself from West Nile Virus?


West Nile Virus
was first detected in North America in 1999 and in Utah in 2003. West Nile Virus is transmitted by female mosquitoes while taking a blood meal that is required to develop eggs. Horses, humans and some birds (particularly crows, ravens and jays) are susceptible to West Nile Virus. So far in 2012, one human case has been confirmed in Utah.

 Approximately 80 percent of humans infected with West Nile Virus never show symptoms. Most people’s immune systems are healthy enough to overcome the virus. Up to 20 percent of those bitten will develop West Nile Fever and display symptoms similar to the flu. Symptoms typically last a few days and should be treated by drinking fluids and resting. About one in 150 people infected will become seriously ill and require hospitalization. People over 50 years of age and those with compromised immune systems are at higher risk to develop more serious complications from West Nile Virus.
