The West Nile Virus has infected individuals in seven states, with some cases progressing to severe illness, according to recent reports from the Centers for Disease Control and Prevention (CDC).
As of now, nine people in Arizona, Arkansas, Kansas, Maryland, Michigan, Mississippi, and Tennessee have been diagnosed with West Nile Virus. Concurrently, the virus has been detected in non-human hosts such as mosquitoes and birds in at least 18 states, highlighting potential for further spread.
The CDC warns that West Nile Virus is transmitted to humans through mosquito bites after the insects feed on infected birds. Five of the nine reported cases have advanced to neuroinvasive disease, causing conditions like meningitis or encephalitis.
While most infected individuals do not develop symptoms, those over 60 or with certain medical conditions (such as cancer, diabetes, or hypertension) are at higher risk of severe illness. Symptoms of West Nile Virus include high fever, headaches, neck stiffness, disorientation, and neurological complications like tremors and paralysis.
Kate Fowlie, a CDC press officer, emphasized the importance of preventive measures given the early onset of West Nile Virus activity this year. The CDC advises wearing long sleeves and pants, and using insect repellents containing DEET, Picaridin, oil of lemon eucalyptus, or para-menthane-diol, with precautions for children under three years old.
There is currently no cure or vaccine for West Nile Virus, underscoring the critical role of prevention strategies. Additionally, the CDC has raised concerns about the rising incidence of other mosquito-borne illnesses in the U.S., including dengue fever, attributing increased mosquito populations to climate change.
According to the Environmental Protection Agency (EPA), warmer temperatures associated with climate change can accelerate mosquito activity and the incubation period of diseases like West Nile Virus.
