Map Shows Mosquito-Borne West Nile Virus Spreading Across US, Killing Eight
West Nile virus cases have been reported in 32 states so far this year, and at least eight people have died.
The West Nile virus, a mosquito-borne disease, is spreading across the United States, with 222 human cases reported as of August 18, 2021, according to the U.S. Centers for Disease Control and Prevention (CDC). Of these, 156 cases are neuroinvasive, the most severe form of the illness affecting the brain and nervous system. The virus has been detected in 32 states, with Arizona, Texas, and California reporting the highest number of cases.
While most infected individuals do not exhibit symptoms, severe infections can lead to hospitalization and death, with at least eight deaths reported this season. Prevention remains the primary defense against infection, with the CDC recommending the use of EPA registered insect repellents, protective clothing, and eliminating standing water around homes to reduce mosquito populations.
