Mosquito-borne disease defined 

A mosquito-borne disease is a disease that is transmitted to people through the bite of an infected mosquito. 

The diseases infected mosquitoes carry can be caused by a parasite or by viruses. For example, mosquitoes with West Nile virus likely acquired it by feeding on birds already infected with the virus. 

Types of mosquito-borne diseases in Maine

Here in Maine, the most common types of mosquito-borne diseases are: 

  • Eastern equine encephalitis
  • West Nile virus
  • Jamestown Canyon virus

When do symptoms of mosquito-borne diseases first appear?

  • Eastern Equine Encephalitis – 3 to 14 days after a bite from an infected mosquito
  • West Nile virus – 2 to 14 days after a bite from an infected mosquito
  • Jamestown Canyon virus – 3 to 14 days after a bite from an infected mosquito

Signs and symptoms of diseases spread by mosquitoes in Maine

Symptoms of Eastern Equine Encephalitis include fever, chills, muscle and joint pain, and a general feeling of being uncomfortable. Some people infected with EEE may not experience any signs or symptoms.

Symptoms of West Nile virus include fever, headache, muscle and joint pain, stomach issues, and rash. Approximately 80% of people infected with WNV do not show signs or symptoms. 

Symptoms of Jamestown Canyon virus include fever, muscle aches, fatigue, dizziness, and headache. The number of people who don’t show signs or symptoms of this virus is not known.

About 1 out of every 10 people who develop a severe case of West Nile virus will die.

While fatalities attributed to Jamestown Canyon virus are rare, it should be noted that this illness can be severe and cause brain swelling.
