Update - Tuesday, October 22, 2019 

Andover’s EEE Risk level continues to be at the “High” level, and will remain so until there is a hard frost in the region; no such frost has occurred yet. While cooler temperatures will decrease mosquito activity, it does not eliminate the risk of the mosquito borne illness. The Massachusetts Department of Public Health recommends that evening outdoor activities continue to be limited. Residents should continue to use the precautions that have been recommended, including the use of insect repellents.

The state health department will be using the NOAA low temperature maps to help determine when transmission risk will be eliminated.

Update - Friday, September 20, 2019 - 4:00 PM

The mosquito control district continues to sample its trap on Abbot Street weekly to check for EEE in the mosquito population there; no further positive tests have been found in Andover. 

While no additional EEE samples have been isolated in Andover, residents are reminded that there is an expectation that EEE remains an issue here. EEE has been isolated in other communities in the region, and there has been a human case in Essex County. To view the state-wide EEE Risk Map, click here: https://www.mass.gov/files/2019-09/Weekly_Risk_Levels_EEE_92019.jpg.

The risk of human transmission for EEE remains “high”, and residents should curtail outdoor activities after sundown. When outside during high mosquito activity, long sleeved shirts, long pants, and insect repellent should be used.

The Andover Health Division reminds residents of the following mosquito safety guidelines:

Avoid Mosquito Bites

• Limit outdoor activities during peak mosquito hours. Consider cancelling or rescheduling planned outdoor evening events and activities. The hours from dusk to dawn are peak biting times for many mosquitoes. If you are outdoors at any time and notice mosquitoes around you, take steps to avoid being bitten by moving indoors, covering up and/or wearing repellent.
• Clothing can help reduce mosquito bites: Although it may be difficult to do when it’s hot, wearing long sleeves, long pants and socks while outdoors will help keep mosquitoes away from your skin.
• Apply insect repellent if you do go outdoors. Use a repellent with DEET, permethrin, picaridin, IR3535 or oil of lemon eucalyptus according to the instructions on the product label. DEET products should not be used on infants under two months of age and should be used in concentrations of 30 percent or less on older children. Oil of lemon eucalyptus should not be used on children under three years of age. Permethrin products are intended for use on items such as clothing, shoes, bed nets and camping gear and should not be applied directly to your skin.

Mosquito-Proof Your Home

• Drain standing water: Many mosquitoes lay their eggs in standing water. Limit the number of places around your home for mosquitoes to breed by either draining or getting rid of items that hold water. Check rain gutters and drains. Empty any unused flowerpots and wading pools and change water in birdbaths frequently.
• Install or repair window and door screens: Some mosquitoes like to come indoors. Keep them outside by having tightly-fitting screens on all of your windows and doors.

Information about EEE and reports of current and historical EEE virus activity in Massachusetts can be found on the MDPH website here.

According to the Centers for Disease Control and Prevention the EEE virus is a rare cause of brain infections or encephalitis. Very few human cases are reported across the U.S. each year, but EEE can be fatal or leave victims with serious complications and neurological problems.

Update - Friday, August 30, 2019 - 2:40 PM

The Town of Andover’s risk for Eastern Equine Encephalitis (EEE) remains high. The Town of Andover has developed a Frequently Asked Questions document to help residents understand EEE as well as mosquito control efforts.

On Friday August 30, 2019, the Northeast Mosquito Control District’s tests for EEE positive mosquitoes for the Town of Andover came back negative, with no findings of EEE.  The traps were located on Abbot St., Yardley Rd., Westminster Rd., and Woodland Rd. There was one positive in the region, and that came from Methuen.

Despite mosquito traps not finding any additional cases of EEE, the town continues to advise residents that EEE is in the community and to continue to take recommended precautions. These precautions include wearing long sleeved shirts, long pants, and insect repellent when outdoors during times when mosquito activity is at its highest, typically after sunset.

The Town of Andover is requesting additional resources from the Northeast Mosquito Control District to continue their work in the community.

Recommendations for cancellation times for all out door activates remains in effect. All outdoor events in Andover should be concluded by 7:30 p.m. for the weeks of August 26 through September 7. The effective time will roll back as the time of sunset changes in the coming weeks.

The outdoor activity restriction will be in effect until the first hard frost, and will be lifted after consultation with mosquito control and state health officials. Residents are encouraged to enjoy the outdoors during the day, and to use insect repellent when traveling in the woods for protection against both mosquito and tick bites.
