Most people have some localized swelling after a bite then it just goes away on it's own. Occasionally, these bites can lead to serious illnesses such as the West Nile Virus, Dengue, and Eastern Equine Encephalitis Virus. The best way to protect yourself from mosquito-borne disease is to take precautions against mosquito bites.
Use insect repellent when outdoors. Make sure the repellent contains the chemical DEET. Before you start applying, read the product instructions carefully. Put repellent on exposed skin and clothing, but not on skin underneath your clothing. To protect your face from bites, put some repellent on your hands and then apply to your face. Wash your hands afterward. Keep mosquito repellent away from the eyes and mouth.
When possible, wear clothing that fully covers your arms, legs and feet. Wearing light-colored clothing is even better, as mosquitoes are attracted to dark and bright colors.
Avoid using fragrances or scented lotions that may attract mosquitoes.
Avoid outdoor activities during peak mosquito hours from dusk until dawn.
Install screens on the windows in your home and repair screens with rips or tears.
Mosquitoes lay their eggs in water, so regularly get rid of any standing water around your home, such as water that has collected in flower pots, trash cans, rain gutters or swimming pool covers.
