Mosquito virus Massachusetts

As if one mosquito-borne virus wasn't enough, Massachusetts is now battling two. Eastern equine encephalitis (EEE) and West Nile virus (WNV) have both been detected in the state, and health officials are urging residents to take precautions to protect themselves from being bitten.

EEE is a rare but potentially fatal disease that can cause brain inflammation. Symptoms of EEE include fever, headache, nausea, vomiting, and seizures. WNV is a more common virus that can cause fever, headache, muscle aches, and fatigue. In some cases, WNV can also cause more serious neurological problems, such as encephalitis and meningitis.

Both EEE and WNV are transmitted to humans through the bite of an infected mosquito. Mosquitoes become infected with the viruses by feeding on infected birds. The viruses can then be transmitted to humans when the mosquitoes bite them.

There is no specific treatment for EEE or WNV. Treatment is supportive and may include hospitalization, intravenous fluids, and pain medication.

The best way to prevent EEE and WNV is to avoid being bitten by mosquitoes. Residents are urged to take the following precautions:

• Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus.
• Wear long sleeves and pants when outdoors.
• Avoid being outdoors at dusk and dawn, when mosquitoes are most active.
• Remove standing water from your property, which can attract mosquitoes.

If you are bitten by a mosquito, wash the bite area with soap and water. If you develop any symptoms of EEE or WNV, see your doctor immediately.
