West Nile Virus is a disease passed by mosquitoes. In the past 2 weeks cases of West Nile Virus human infections have been reported in Montana, Louisiana, Mississippi, Oregon, New Mexico, Idaho, South Carolina, Pennsylvania, Kentucky and widespread West Nile Virus activity in East Texas. In fact, West Nile Virus human infections have been reported in 39 of the 49 contiguous states.
As of September 13th the Center for Disease Control reports 662 total cases of West Nile Virus and 18 deaths from the virus.
According to the CDC, most people (70-80%) who become infected with West Nile Virus do not develop any symptoms. About 20% of people who are infected will develop a fever with other symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash, which may linger for weeks. Less than 1% of people who are infected with West Nile Virus will develop a serious neurologic illness such as encephalitis or meningitis (inflammation of the brain or surrounding tissues). Some of the neurologic effects may be permanent. About 10% of people who develop neurologic infection due to West Nile virus will die.
That is all.
