WNv: Are mosquitoes to blame?
With the West Nile Virus outbreak set to be the worst in U.S. history, the nation's emergency physicians urge the public to take precautions now to protect from being infected.
"Right now, the CDC is seeing cases in practically every state in the country," said Dr. David Seaberg, president of the American College of Emergency Physicians. "This is a problem that affects everyone, everywhere. But simple steps can stand in the way of a person being infected with West Nile."
West Nile Virus, which is a disease spread by mosquitos, causes only mild, flu-like symptoms in 20 percent of cases, according to the Centers for Disease Control and Prevention (CDC). Most people (about 4 out of 5) who are infected show no symptoms at all. But in rare cases, some will develop severe symptoms that can include high fever, disorientation, coma, tremors, convulsions, vision loss, along with several others. It can cause permanent neurological damage and even death.
So far in 2012, 47 states have reported more than 1,100 cases West Nile cases, including 41 deaths, according to the CDC, with 75 percent of the cases reported in Texas, Mississippi, Louisiana, South Dakota and Oklahoma.
