DEM: August 26 West Nile/EEE Status Update

PROVIDENCE - The Department of Environmental Management announces that test results from 97 mosquito pools, or samples, from 34 traps set statewide during the week of August 12 are negative for both West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE). Results from 115 pools collected from 33 traps set August 18 are pending at the RI Department of Health (HEALTH) Laboratory.

To date, there has been one isolation of WNV in Rhode Island. EEE has not been found this season in Rhode Island. However, both diseases are currently present in our area. WNV and EEE have recently been found in mosquito samples in Massachusetts, and WNV has been isolated from mosquitoes trapped in Connecticut.

Throughout the mosquito season, residents are encouraged to protect themselves by eliminating mosquito breeding grounds and avoiding mosquito bites. Personal protection is the first line of defense against mosquitoes that can carry diseases such as West Nile Virus and EEE and is by far the most effective way of avoiding infection.

Eliminate mosquito breeding grounds from yards by removing anything that holds standing water, such as old tires, buckets, junk and debris, clean gutters so that they drain correctly, and maintain swimming pools properly. Mosquitoes breed in standing water. Just one cup of standing water can produce hundreds of mosquitoes. Avoid mosquito bites by using screens on windows and doors, covering up at dawn and dusk, and putting mosquito netting over playpens and baby carriages when they are outside. Also, use mosquito repellent, but with no more than 30 percent DEET. Do not use repellent on infants.

Mosquitoes are trapped every week statewide by DEM staff and tested at the HEALTH Laboratory. DEM will normally report mosquito test results once a week on a routine basis, with additional reports as necessary. Test results from mosquitoes trapped this week will be included in next week's announcement. Positive mosquito test results will generally trigger additional trapping to assess risk.
