A 41-year-old woman has dengue fever, according to Osceola County Health Department.

The health department said they do not know if the woman traveled outside the country at all, but the disease was confirmed through lab tests.

They are also working to confirm a second case of dengue fever in a 73-year-old man.

The health department is warning people to be careful with mosquitoes and mosquito bites. Dengue is a viral disease transferred by a breed of mosquito common in the tropical and the southeastern United States. Reported cases in Florida are rare. It is not spread from person to person.

A Seminole County man had a confirmed case of dengue fever. We told you about that earlier this week.

Symptoms of dengue fever vary -- infants and young children may have a fever and a rash. Older children and adults can get a more severe case of the disease, with high fever, severe headache, pain behind the eyes, muscle and joint pains and rash.

If you have any of these symptoms, you should see a doctor.

You should also safeguard against mosquitoes. To do that, remember the "Five D's":

  • Drain standing water around your house
  • Use spray with DEET if you go outside
  • Dress in cloths that cover most of your skin
  • Try not to go out a lot during dusk and dawn
