As fall arrives, the threat of mosquito-borne illnesses like Eastern equine encephalitis (EEE) and West Nile virus is far from over. A New York resident recently died from EEE, marking the state's first confirmed human case since 2015, and highlighting the growing concern over these dangerous viruses.

Current Situation:

  • EEE: At least 10 cases have been reported nationwide this year, with deaths confirmed in New York and New Hampshire. EEE is a rare but life-threatening virus spread by mosquitoes.
  • West Nile Virus: The CDC has reported 659 human cases in the U.S. this year. Symptoms can range from mild (fever, headache) to severe (neurological complications).
  • Dengue Fever: Over 5,000 cases have been logged in the U.S. this year, with Florida, New York, California, and Massachusetts being the hardest hit.

How to Protect Yourself:

  • Use Insect Repellent: Apply EPA-registered repellents like DEET or Picaridin to your skin and clothing when outdoors.
  • Wear Protective Clothing: Opt for loose-fitting, light-colored, long-sleeved clothing, socks, and shoes.
  • Avoid Peak Mosquito Hours: Try to stay indoors during dusk and dawn when mosquitoes are most active.
  • Fix Screens: Repair damaged window and door screens to keep mosquitoes out of your home.
  • Eliminate Standing Water: Remove small pools of standing water around your home, and toss items like flower pots and toys that can collect water.

Recognizing the Symptoms:

  • EEE: Symptoms include fever, headache, irritability, vomiting, and, in severe cases, convulsions and coma.
  • West Nile Virus: Symptoms range from fever and headache to rash, vomiting, and diarrhea.
  • Dengue Fever: High fever, severe headache (especially behind the eyes), muscle and joint pain, nausea, vomiting, and a flat, red rash.

What to Do if You Get Sick:

If you suspect you've contracted a mosquito-borne illness, rest and stay hydrated. Contact your doctor immediately if you experience severe symptoms like a high fever, stiff neck, muscle weakness, or difficulty breathing.

As mosquito season extends into the fall, it’s crucial to remain vigilant. Protect yourself and your family by following these preventive measures and staying informed about the latest developments in mosquito-borne diseases.
