What is West Nile?

Per the Cleveland Clinic's website, West Nile is a virus that spreads through mosquito bites.

"Most people who get infected don’t have symptoms. But about 1 in 5 people have a fever, headache, body aches and other flu-like symptoms," read a portion of the website. "Rarely, West Nile virus infects your nervous system and causes serious brain or spinal cord inflammation."

Why you should care:

Cleveland Clinic's website states that some people are at a higher risk of getting seriously ill if they contract the West Nile Virus. They may include:

  • Those over 60 years old
  • Those who received an organ transplant
  • Those who have cancer
  • Those who have diabetes
  • Those who have high blood pressure
  • Those who have kidney disease

What you can do:

MCDPC officials have the following advice for people:

  • Use EPA-registered indent repellents when outdoors, such as products that contain DEET. The Mayo Clinic also says wearing lightweight, long-sleeved short or long pants could help prevent West Nile by covering more of the body while outdoors.
  • Get rid of standing water around the home and yard as a way to eliminate mosquito breeding grounds.
  • Patch up or replace damaged window and door screens
