Health officials said they have confirmed 2015's first case of West Nile virus in a human in Florida.

The case involves a woman who lives in Walton County. Officials have not released any further information about the woman.

So far, 38 other states have confirmed cases of the virus. In Pinellas County, the virus was detected in a sentinel chicken earlier this month, but no human cases had been reported.

Health officials are urging Floridians to take steps to protect themselves against contracting the mosquito-borne virus, including:

  • Draining standing water near or in your home
  • Making sure screens are intact
  • Keeping skin covered with clothing and mosquito repellent

Most people who contract the infection - about 80 percent - have no symptoms. In those who do develop symptoms, most experience a mild illness with conditions like headache, fever, pain and fatigue. They typically appear between two and 14 days after a bite.

People who are over the age of 50 or who have weakened immune systems seem to be at increased risk for severe disease.

Most mild infections are usually overcome with little to no medical intervention, but if you experience serious side effects, you should seek medical attention immediately.
