PROVIDENCE - The Department of Environmental Management announces that test results from 105 mosquito pools, or samples, from 37 traps set statewide during the week of August 3 are negative for both West Nile Virus and Eastern Equine Encephalitis. Results from 102 pools collected from 32 traps set August 12 are pending at the Rhode Island State Health Laboratories.
To date, there have been no isolations of Eastern Equine Encephalitis or West Nile Virus in Rhode Island. However, West Nile Virus has been isolated from mosquito samples in neighboring states. While the disease hasn't been found in our area, this should serve as a reminder to Rhode Islanders that mosquito-borne diseases become more prevalent in the latter part of the summer and into the fall.
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 Rhode Island State Health Laboratories. DEM will normally report mosquito test results once a week on a routine basis from late June through September, 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.
