West Nile Virus Infection – Encephalitis – Lower Respiratory Tract Infection – Respiratory failure type II-CASE REPORT

West Nile virus (WNV) is the leading cause of mosquito-borne disease in the continental United States. It is most commonly spread to people by the bite of an infected mosquito. Cases of WNV occur during mosquito season, which starts in the summer and continues through fall. There are no vaccines to prevent or medications to treat WNV in people. Fortunately, most people infected with WNV do not feel sick. About 20% of people who are infected develop a fever and other symptoms. About 1% infected people develop a serious, sometimes fatal, illness.
