EEE and West Nile Found In Durham
UNH Urges Campus Community To Review
Office of Environmental Health and Safety is urging the campus
community to take precautions after the State
Public Health Laboratory recently identified two birds in Durham
that have tested positive for Eastern Equine Encephalitis (EEE)
and West Nile virus.
In total, four birds and a horse recently tested positive for Eastern
Equine Encephalitis (EEE). The birds were found in Merrimack, Webster,
Plymouth and Durham and bring the total number of birds that have
tested for EEE this year to 46. A horse from Webster also tested
positive for the virus, bringing the total among horses to eight
New Hampshire has seen five cases of EEE in humans.
Additionally, a bird in Durham has tested positive for West Nile
virus, the 32nd bird in the state this season.
"We are not done with mosquito season yet and we are still
seeing EEE show up in new towns such as Merrimack, Webster and Durham,"
Department of Health and Human Services Commissioner John Stephen
said. "I want to repeat the message in case anyone hasn't heard
it yet -- prevention works. EEE and West Nile virus are entirely
preventable if you take precaution. Use an effective mosquito repellant,
wear long sleeves and pants when outside, particularly during dawn
and dusk and drain any standing water near your home."
Office of Environmental Health and Safety encourages faculty,
staff and students to review its prevention
guidelines for EEE/West Nile virus (pdf).
In addition, DHHS has set up a toll-free Hotline for EEE/West Nile
virus at 1-866-273-6453. Anyone with questions can call from 8 a.m.
to 4:30 p.m. for information about these viruses. The department's
website has EEE
and prevention guidelines.
"With temperatures in the forecast staying the 80s and no sign
of freezing weather in sight, we should continue to expect considerable
mosquito activity until we see frost. Many have taken the preventive
steps to avoid mosquito bites and I commend them. We want everyone
to stay safe and enjoy the outdoors," Stephen said.
Prevention Guidelines for West Nile Virus and Eastern Equine
From UNH Office
of Environmental Health and Safety
The main control in preventing EEE and West Nile is to avoid being
bitten by the mosquitoes carrying the virus.
• To minimize exposure to viruses, people should stay indoors
during dusk, dawn, and in the early evening from June to October,
when mosquitoes are most active.
• Whenever outdoors, insect repellant containing permethrin
or 30 percent N,Ndiethyl- meta-toluamide (DEET) for adults and 10
percent DEET for children should be applied to exposed skin and to clothing.
• DEET should only be used according to manufacturer’s
directions. More information regarding insect repellant and its
proper use, or pesticide sprays, can be found at:
• Long-sleeved shirts, long pants, and socks are recommended
when spending time outdoors.
• Doors and windows to homes should remain closed and have
• Mosquitoes breed in standing water (such as water in wheelbarrows,
old tires and buckets). Remove all empty all vesicles containing standing
water. Keep swimming pools and hot tubs clean, chlorinated and covered
when not in use.
• Repair leaky outdoor faucets and change the water in bird
baths and pet bowls at least twice a week. In addition, keep gutters
clean and in good repair.
• Vaccinate horse against the EEE and West Nile viruses.
