Somerville has drawn the short straw in this summer's mosquito lottery. City Health and Human Services officials warned Monday that testing by the Massachusetts Department of Public Health found West Nile virus in mosquito samples collected inside Somerville. The official risk level for the city is still listed as low, and so far there have been no human or animal illnesses reported, but the positive traps put Somerville squarely on this season's arbovirus map.
The state had already logged its first West Nile positive mosquito of the year from a June 16 collection in the Berkshires, according to Boston.com. State health officials noted that warmer weather typically marks the start of arbovirus activity and pointed back to nine confirmed human cases in Massachusetts last year as a reminder of why this testing matters.
Somerville Advisory And Local Testing
As outlined in an advisory from City of Somerville, the WNV positive mosquito samples in Somerville came from traps checked in mid-June. Collections on June 16 and June 21 turned up infected mosquitoes, and the city notes that 21 mosquito samples across Massachusetts have now tested positive for West Nile this season. Officials stressed that the overall risk level for Somerville remains low, while urging residents to stick with basic prevention steps like using repellent, covering exposed skin, and getting rid of standing water where mosquitoes breed.
How To Protect Yourself
The Centers for Disease Control and Prevention keeps the advice pretty simple. Use an EPA registered repellent, such as products with DEET, picaridin, or oil of lemon eucalyptus. Treat clothing and gear with permethrin instead of putting it directly on your skin, and try to avoid being outdoors during peak mosquito hours at dawn and dusk when you can. Public health guidance also leans hard on cleanup: drain or refresh standing water in flowerpots, birdbaths, clogged gutters, and anything else that can turn into a backyard mosquito nursery.
If you develop fever, a severe headache, a stiff neck, or neurologic symptoms after a mosquito bite, health officials say you should contact your medical provider. Most infected people never get sick at all, but older adults are at higher risk for severe disease, according to the guidance on CDC.
Other Local Detections And Municipal Responses
Somerville is not the only community getting tagged by the lab this month. The Cambridge Public Health Department reported that the state public health laboratory confirmed WNV positive mosquito samples from Boston and Newton, according to Cambridge Public Health. In Worcester, local notices and coverage detail positive mosquito traps and city plans for targeted truck-mounted spraying in nearby neighborhoods, as reported in coverage of West Nile hits Worcester mosquitoes.
State and local officials say the best defense is sticking with simple, consistent prevention and keeping an eye on official alerts. Residents can track the evolving picture on the state's arbovirus dashboard at Massachusetts DPH. Reporting by WBZ NewsRadio and information from the city supplied details for this story.
