From The CDC: Revised Guidelines for Surveillance, Prevention, and Control of West Nile Virus Infection
Although it is not known when or how West Nile (WN) virus was introduced into North America, international travel of infected persons to New York, importation of infected birds or mosquitoes, or migration of infected birds are all possibilities. WN virus can infect a wide range of vertebrates; in humans it usually produces either asymptomatic infection or mild febrile disease, sometimes accompanied by rash, but it can cause severe and fatal infection in a small percentage of patients. In 1999 in New York, approximately 40% of laboratory-positive humans with encephalitis or meningitis had severe muscle weakness; 10% developed flaccid paralysis with electromyographic findings consistent with axonal neuropathy. The human case-fatality rate in the US has been about 11%. Get the most current guidelines on the topic of WN in today's issue of Vidyya. more |
