What Diseases Do Mosquitoes Carry in Florida?

If you’re planning to visit or move to the Fort Myers or Naples area, you may have asked yourself this very important question…

“What diseases do mosquitoes carry in Florida?”

This is the third of 7 Things YOU Need to Know About Southwest Florida Mosquitoes, a FREE eBook provided by Larue Pest Management, Inc.

While many of us are irritated by the itchy, red bumps that mosquito bites cause, we easily forget that we are also in danger of mosquito-borne illnesses that these insects can carry and transmit to humans.

Although it is rare for someone in Southwest Florida to contract one of these illnesses, we think education is the best form of prevention. At Larue, we hope that mosquito disease awareness will help you remember to be cautious and thoughtful when you are outdoors.

Below are the top three diseases that mosquitoes carry in Florida that we think you should learn about:

West Nile Virus

West Nile Virus is probably the most commonly known disease that mosquitoes carry in Florida and symptoms include:

  • Rash
  • Fever
  • Headache
  • Nausea or vomiting
  • Neck stiffness
  • Disorientation
  • Vision loss
  • Tremors (shakes)

Most people who are infected with West Nile will not experience extreme symptoms, but those with a compromised immune system, the elderly or infants are more likely to feel the negative effects.

Chikungunya Virus

The chikungunya virus is another mosquito-borne illness that has been making news as it’s appearance in Florida steadily increases. Currently, it’s spreading across the Caribbean at an alarming rate and generally cases that have been reported locally were imported by people returning from those regions.

Once a person becomes infected, there’s an incubation period of three to seven days before symptoms present themselves. The most common signs of the virus are fever and joint pain, typically in multiple joints. Like any viral syndrome, chikungunya can also cause headaches, muscle aches, rash and joint swelling.

Rarely lethal, there is no cure for chikungunya, and its effects can be quite debilitating. While some patients will suffer a minor fever and mild joint pain, others can experience very high fevers and sustained joint pain for several weeks or even months.


Encephalitis is another serious illness carried and transmitted via Florida mosquitoes. Although it is very dangerous, it’s also very rare. Infected individuals may feel high fever, stiff neck, headache, confusion, and lethargy a few days after a bite. The infection causes swelling of the brain and can damage the nervous system.

Fortunately for us, we are not likely to experience malaria or yellow fever, but if you are planning on traveling to a less developed country, where these and other mosquito-borne illnesses are more common, be sure to check with your doctor first.
