Mosquito Borne Diseases
West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE or 'Triple E") are viruses that can cause minor to serious illness like encephalitis or meningitis from an extremely small number of mosquitoes. People may be exposed to other diseases spread by mosquitoes when traveling in the world like Zika virus and Dengue fever.
Prevention steps to reduce mosquito exposure
Some simple steps to take to protect yourself and your family from mosquito bites, and the illnesses they can cause are:
- Use insect repellents when you are outdoors and buy pretreated clothing
- Wear long-sleeved clothing, pants, and socks
- Avoid activities outside between the hours from dusk to dawn during April to late October
- Repair damaged window and door screens
- Remove any standing water from areas around your home(pails, house gutters, etc.)
