BOSTON, MA – It is summer, and with the summer come mosquitoes. West Nile virus has been detected in Massachusetts mosquitoes for the first time this year, health officials said Tuesday. The presence of the virus was confirmed by the Massachusetts State Public Health Laboratory in a sample of mosquitoes that was collected June 20 in the town of Weymouth in Norfolk County.
No human or animal cases of West Nile virus or Eastern equine encephalitis have been detected so far this year, according to the Massachusetts Department of Public Health. There is no high level of risk or change in the level of risk associated with this finding, but public servants want the public to remember how to avoid biting themselves.
"The first sample of WNV positive mosquitoes is often identified in Massachusetts during the last week of June," said Catherine Brown, an associate epidemiologist at DPH. "The risk of human infection usually develops during the season with maximum risk in August."
West Nile virus is usually passed on to humans by the bite of an infected mosquito, according to health officials. In 2017, there were six human cases of infection in Massachusetts. Although it can infect people of any age, people over the age of 50 are at a higher risk of contracting the disease. Most people infected with WNV will have no symptoms. When present, the symptoms tend to include fever and influenza-like illness, according to health officials. In rare cases, a more serious illness may occur.
People have an important role to play in protecting themselves and their loved ones against diseases caused by mosquitoes, Brown said in a statement.
"Prevention tools include the use of a mosquito repellent product with an EPA-approved ingredient according to the instructions on the label, clothing to reduce exposed skin when the weather allows it, stagnant water to prevent mosquito breeding and mosquito repair. your house, "she said.
Because the symptoms are not always so pronounced, people who develop a serious illness with West Nile virus are often reported. Between 2000 and 2010, 67 people were infected with West Nile virus in Massachusetts. Six of these people are dead.
According to the State Department of Health only 10 percent of people who develop a serious illness have died of infection.
There is no specific treatment for West Nile virus infections. People with mild West Nile virus infections are recovering themselves, health officials say. People with severe West Nile virus infections almost always have to be hospitalized.

Organize a neighborhood clean-up day to pick up containers from vacant lots and parks and encourage people to keep their yards without stagnant water.
