Onondaga County Interim Health Commissioner, Michelle Mignano, was notified by the New York State Department of Health today that an Onondaga County adult resident has been diagnosed with Eastern Equine Encephalitis (EEE). Ms. Mignano explained, “This is the first known human case of EEE in Onondaga County since 2010. It is essential that residents consistently take measures to avoid being bitten by mosquitoes”. Mignano stated that the individual is currently hospitalized and is in stable condition. To protect the privacy of this patient and of the family, additional details are not being shared with the public.
EEE is a rare but dangerous viral infection that is transmitted through the bite of an infected mosquito. The virus can cause encephalitis, or inflammation of the brain. Initial symptoms, which usually start 4-10 days after the bite, can include fever, headache, and vomiting. Illness can then progress to altered mental status, confusion, seizures, coma, and even death. The greatest risk for infection with this virus is for people who spend a lot of time outdoors.
The Onondaga County Health Department conducted aerial spraying of the Cicero swamp on July 22, 2014 and explained if additional spraying is determined necessary, the public will be notified through the media and by the emergency reverse 911 notification system.
It is important that the public continue to take measures to minimize being bitten by mosquitoes and to keep your yard free from standing water to reduce the mosquito population near your home. Mosquitoes are most active between dusk and dawn. Personal protection is advised during outdoor activities. Personal protection measures include wearing shoes and socks, long pants, and a long-sleeved shirt when outside for a long period of time. Applying a mosquito repellent containing DEET, Picaridin, Oil of Lemon Eucalyptus, or IR3535 is also recommended to prevent mosquito bites. Do not put the repellent directly onto children. Put it on your hands and apply it to your child. Do not put insect repellent on your face. Wash skin and clothing after returning indoors. Follow the manufacturer’s recommendations for application.
The following are ways of helping to reduce mosquito breeding grounds:
- Throw away outdoor containers, ceramic pots, or containers that hold water
- Remove all tires from your property
- Drill holes in the bottoms of recycling containers that are kept outdoors
- Clean clogged rain gutters and make sure they continue to work properly
- Turn over wheelbarrows and wading pools when not in use
- Change water in bird baths at least every four days
- Clear vegetation and debris from the edges of ponds
- Clean chlorinated swimming pools, outdoor saunas, and hot tubs
- Drain water from pool covers
- Use landscaping to eliminate low spots where standing water accumulates
