Mosquitoes trapped on the South Shore of MA have been confirmed carriers of West Nile virus, health officials said. Some predatory birds become infected after eating sick or dead birds that were already infected with the virus.
West Nile has been detected in CT every year since 1999.
"No vaccine or specific antiviral treatments for West Nile virus infection are available", the CDC website states.
Residents are reminded to protect themselves from mosquito bites and mosquito-borne diseases.
Those infected with WNV may show severe symptoms, mild symptoms or no symptoms at all.
What are the symptoms of West Nile? About 80 percent of people who are infected will not show any symptoms.
Symptoms that may be present are: high fever, headache, neck stiffness, muscle weakness or paralysis, and confusion. If contracted, symptoms include mild flu-like symptoms, progresses into disorientation, seizures, coma, encephalitis (an inflammation of the brain) and in the most severe cases, individuals die. In very rare cases, the virus can lead to neuroinvasive diseases like encephalitis or meningitis.
People who are experiencing symptoms of West Nile virus are encouraged to contact their local health care provider.
"The first West Nile virus positive mosquitoes of the season have been identified", said Dr. Philip Armstrong, Medical Entomologist at the CAES.
Wear shoes, socks, long trousers, and a long-sleeved shirt when outdoors for long periods of time, or when mosquitoes are more active.
If a resident has stagnant pools of water on their property, they can buy Bti products at lawn and garden, outdoor supply, home improvement and other stores. Apply insect repellent containing DEET to exposed skin and clothing.
