DEM: SEPTEMBER 8 WEST NILE/EEE STATUS UPDATE
Number of EEE-Positive Mosquitoes in Southern New England Prompts State Officials to Issue Reminder that Rhode Islanders Now at Higher than Average Risk for EEE

PROVIDENCE - The Department of Environmental Management announces that test results from 177 mosquito pools from a total of 52 traps set statewide between August 18 and 23 are negative for both West Nile Virus and Eastern Equine Encephalitis (EEE). Twenty additional pools are pending, and one, from August 23, was previously reported as positive for EEE.

However, Alan Gettman, Ph.D., DEM's Mosquito Abatement Coordinator issues a reminder that the increasing numbers of mosquito pools, or samples, testing positive for Eastern Equine Encephalitis in Southern New England indicates that "We are now clearly at a higher than normal risk for EEE. The evidence is there."

Last week's report of the death of a teenager from Massachusetts, the second death in that state from EEE this year, as well as the recent report of eight EEE-positive mosquito pools from a number of different mosquito species in Stonington and North Stonington, Connecticut add to the concern. To date, four mosquito pools in Rhode Island have tested positive for EEE, as have 25 mosquito pools in southeastern Massachusetts and 13 in eastern Connecticut.

"Those findings, coupled with the heavy rains during the first half of August that hatched eggs, producing a new crop of mosquitoes that we are experiencing now, increases the possibility of disease transmission," Gettman said.

Because of the heightened health risk, all Rhode Islanders should take extra care to protect themselves, particularly when mosquito biting activity is high. Biting activity depends on several conditions. It generally is greatest from dusk to dawn. During the day it decreases in sunny areas at lower temperatures and increases in shady areas at higher temperatures. Biting activity also generally increases with high humidity and with low wind.

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. People should routinely use mosquito repellent and cover up when mosquito biting activity is greatest. They should place mosquito netting over playpens and carriages outside, and be sure that screens are in good repair. Mosquito repellent should contain no more than 30 percent DEET, and it should not be used on infants.

Mosquitoes are trapped every week statewide by DEM staff and tested at the RI Department of Health (HEALTH) laboratory. DEM will normally report mosquito test results once a week on a routine basis, with additional reports as necessary. Test results from last week's trapping and any routine pending results will be reported by DEM next Wednesday.
