West Nile Virus
Fight the Bite
West Nile Virus is here to stay in Idaho. You can protect yourself with a few easy steps.
You Can Avoid Illness
Infected mosquitoes can carry West Nile Virus (WNV) and spread it to people and animals.
Four out of five people infected with WNV won't have any symptoms, but some people can become very sick and some will die. Although infections can be more serious in older people due to lowered immune systems, the virus can cause severe illness in all ages. Symptoms of WNV show up around 3 to 14 days after a bite from an infected mosquito. You can only get WNV from a mosquito bite - you can't catch WNV from a person or animal.
Illness from West Nile Virus
West Nile Virus symptoms may include fever, tiredness, headaches, a rash, and sore muscles. Symptoms can be very serious and painful, and can last anywhere from a few days to months.
West Nile Virus can cause neuroinvasive disease. This means the virus may infect the brain or nerves causing very serious problems like brain swelling and paralysis. A person with West Nile Neuroinvasive Disease may have seizures, tired arms and legs, a rash, stomach pain, and may seem confused. Recovery can take months and may lead to long-term problems, and in rare cases cause death.
Your doctor is the best person to talk to about West Nile Virus.
You Can Protect Yourself and Your Family
Avoid mosquito bites by following these important, but easy steps:
You Can Protect Your Horse
Horses can become very sick from WNV, and some will die. You can protect your horse with a yearly shot available from veterinarians or through feed and tack stores. You should clean water troughs once a week to reduce mosquito larvae.
Don't over water your pasture. This creates puddles where mosquitoes like to breed.
You Can Enjoy the Outdoors
You can still enjoy Idaho's beautiful outdoors and protect your family from harmful mosquito bites.
Hunters should not harvest or eat wild game animals that appear sick. Always wear latex or rubber gloves when cleaning and processing game and always cook meat thoroughly before eating.
You Can Report Dead Birds
Dead crows, magpies, ravens, jays, and hawks are usually an early warning sign that mosquitoes carrying WNV are in your area. If you find one of these birds, call your local Fish and Game office. By calling, you can help monitor where WNV may be. Always wear latex or rubber gloves if you handle any dead animals.
You Can Promote Community Action
Reducing mosquito breeding habitat in the community helps everyone. Reduce overwatering in parks, golf courses, and public recreation areas. Talk to your homeowners association about controlling mosquito populations in community catchment ponds. Pesticides can be extremely dangerous if not applied correctly. Application of pesticides in community settings should be left to licensed applicators, so that residents and the environment are not harmed.
Counties and communities can form mosquito abatement districts to help control mosquito populations too. Abatement districts develop effective, long-term plans to control mosquito populations and are funded through local taxation. By Idaho law, abatement districts are the only public entity that can provide area-wide mosquito control. Bingham and Bannock Counties have formed these abatement districts.
