DPH Warning on Mosquitoes and EEE

For Immediate Release                          September 11, 2019     

 DEPARTMENT OF PUBLIC HEALTH ADVISES CONNECTICUT RESIDENTS TO CONTINUE TAKING EXTRA PRECAUTIONS TO PREVENT CONTRACTING EASTERN EQUINE ENCEPHALITIS

RESIDENTS ARE ADVISED TO PROTECT THEMSELVES AND THEIR CHILDREN BY AVOIDING OUTDOOR ACTIVITY FROM DUSK TO DAWN, WHEN MOSQUITOES ARE MOST ACTIVE
 
Hartford – The Connecticut Department of Public Health today is urging residents to continue personal preventive measures to avoid mosquito bites and reduce the chance of contracting eastern equine encephalitis (EEE) virus. Residents are advised to protect themselves and their children by minimizing outdoor activity from dusk to dawn, when mosquitoes are most active.  The mosquitoes that carry the virus are active until the first heavy frost.
 
The EEE virus has been identified in mosquitoes in 12 towns and in horses in two other towns.  Towns where mosquitoes have tested positive for EEE include: Chester, Haddam, Hampton, Groton, Killingworth, Ledyard, Madison, North Stonington, Plainfield, Shelton, Stonington, and Voluntown.  Horses have tested positive for EEE virus in Colchester and Columbia this season, and the virus has been detected in a flock of wild pheasants.  Other states throughout the Northeast are also experiencing an active season for EEE.  In addition to the virus being found in mosquitoes, human cases of EEE infection, including fatalities, have been identified this year in Massachusetts, Rhode Island, and New Jersey.  No human cases of EEE have been identified in Connecticut so far this year.
 
“Connecticut residents, especially those in the eastern part of the state, should continue to take mosquitoes seriously and take routine precautions to prevent mosquito bites.” cautioned DPH Commissioner Renée Coleman Mitchell. “The mosquitoes that carry the virus are active until the first heavy frost.”
 

The DPH advises against unnecessary trips into mosquito breeding grounds and marshes as the mosquitoes that transmit EEE virus are associated with freshwater swamps and are most active at dusk and dawn.  Overnight camping or other substantial outdoor exposure in freshwater swamps in Connecticut should be avoided.  Even though the temperatures are getting cooler, it is important to remember mosquito season is not over and residents should continue to take measures to prevent mosquito bites, including wearing protective clothing and using repellents.
 
Although EEE-infected mosquitoes continue to be detected in the southeastern corner of the State, the numbers are beginning to decline and we are not experiencing the excessively high levels of activity seen in Massachusetts.  There are currently no plans to implement widespread pesticide sprays in the State. 
 
The EEE virus is a rare but serious disease transmitted by mosquitoes which acquire the virus by feeding on wild birds. The virus cannot be spread person-to-person or from horses to humans. On average, there are 6 human cases of EEE reported each year in the United States. Symptoms include fever, headache, stiff neck, and reduced consciousness. Individuals experiencing these symptoms should seek medical care immediately. Approximately 25-50% of cases are fatal and one-half of survivors suffer permanent neurological damage. In Connecticut, the first locallyacquired human case occurred in the fall of 2013. That patient died from the infection.     Personal precautions to avoid mosquito bites include:   Be sure door and window screens are tight fitting and in good repair.  While outdoors, wear shoes, socks, long pants, and long-sleeved shirts. Clothing should be light colored and made of tightly woven materials that keep mosquitoes away from the skin.  Consider using mosquito repellent when it is necessary to be outdoors and always use them according to label instructions. The most effective repellents contain DEET or Picaridin.   Limit infants’ and children’s exposure to mosquitos and dress them in protective clothing when outdoors.   Use mosquito netting if sleeping outdoors.

NDDH Warns of Mosquito-Transmitted Illnesses

SWAT Campaign Helps Residents to Remember Prevention Tips
 
(BROOKLYN) – The Northeast District Department of Health (NDDH) is reminding residents to take steps to avoid being bitten by mosquitoes. West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE) are two diseases transmitted by infected mosquitoes that are of particular concern in the late summer and fall. The State Mosquito Management Program reports that an increasing number of mosquitoes trapped by the Connecticut Agricultural Experiment Station are testing positive for WNV and EEE.
 
Both WNV and EEE can cause severe disease in humans. While WNV infections are usually not fatal, patients who develop meningitis or encephalitis may suffer long lasting symptoms of the nervous system.  EEE is one of the most severe mosquito-transmitted diseases in the country. It is a rare but potentially deadly disease. A fatal human infection of EEE in eastern Connecticut was recorded in 2013.
 
Horses and other animals can also contract WNV and EEE. Horse owners are reminded to review vaccination records with their veterinarians to ensure that EEE and WNV vaccinations are current and their horses are protected during the mosquito season.
 
Residents of Connecticut are at highest risk of acquiring WNV and EEE infections in August and September when the number of infected mosquitoes peaks. To help residents lower their risk of acquiring mosquito-borne illnesses, NDDH developed the SWAT campaign that offers tips to avoid being bitten.
 
 
 
 
“SWAT is an easy acronym to remember to prevent mosquito bites, “said Susan Starkey, NDDH Director of Health. “Screens on doors and windows should be tight-fitting and in good repair; Wear protective clothing such as shoes, socks, long pants and long-sleeved shirts to cover bare skin; Apply insect repellent according to instructions when going outdoors and be particularly careful at dawn and dusk when mosquitoes are most active. Most importantly, Toss any standing water that may be collecting on your property. Water in wading pools, bird baths, buckets, barrels, flower pots, pet dishes, and tire swings should be changed or emptied regularly. Clogged roof gutters should be cleaned. These simple steps can help you reduce the risk for you and people you care about.”
 
Connecticut Mosquito Management Program The response to mosquito transmitted diseases in Connecticut is a collaborative inter-agency effort involving the Department of Energy and Environmental Protection, the Connecticut Agricultural Experiment Station, the Department of Public Health, the Department of Agriculture and the Department of Pathobiology at the University of Connecticut. These agencies are responsible for monitoring mosquito populations and the potential public health threat of mosquito-borne diseases. The CAES maintains a network of 91 mosquito-trapping stations in 72 municipalities throughout the state. CAES begins mosquito trapping and testing in June and continues into October.   For information on WNV and EEE, what can be done to prevent getting bitten by mosquitoes, the latest mosquito test results and human infections, visit the Connecticut Mosquito Management Program web site at https://portal.ct.gov/Mosquito
