What is West Nile Virus?
West Nile virus (WNV) is a mosquito-borne virus that can cause serious neurological disease, including meningitis, encephalitis, and even death. It has been found in Africa, the Middle East, Europe and North America. In the United States it was first detected in 1999 in New York City and has since spread to all parts of the country.The virus is transmitted by mosquitoes that acquire it from feeding on birds infected with WNV. The primary way for humans to get WNV is through the bite of an infected mosquito; however, other forms of transmission include transplantation of organs or blood products from an infected person or contact with infected animals such as horses or birds.Symptoms of WNV infection can range from mild fever to severe neurologic illness such as meningitis and encephalitis (inflammation of the brain). Most people who are infected with WNV do not show any symptoms at all; however, those who do may experience fever, headache, body aches and occasionally skin rash or swollen lymph nodes. Severe cases may include confusion, paralysis or coma.Prevention is key when it comes to controlling West Nile Virus infection risk. To reduce exposure to bites from mosquitoes carrying West Nile Virus: avoid being outdoors during peak biting times (dusk and dawn); wear protective clothing when outdoors; use insect repellents containing DEET; empty containers around your home that collect water where mosquitoes could breed; use screens on windows and doors; repair any holes in screens so mosquitoes can’t enter your home; maintain swimming pools properly – empty if not used regularly -and keep them chlorinated and covered when not in use. People over 50 years old are at higher risk for complications due to West Nile Virus infection so they should take extra precautions against mosquito bites by wearing long sleeves/pants while outside during peak biting times. In conclusion, West Nile Virus is a serious infectious disease caused by a mosquito-borne virus which can lead to severe neurological illnesses such as meningitis and encephalitis if left untreated or undetected early enough. Prevention measures such as using insect repellent containing DEET while outdoors can help reduce your chances of being bitten by an infected mosquito thereby reducing risk for infection with this virus. People over 50 years old should take extra precautions against mosquito bites including wearing long sleeves/pants while outside during peak biting times.
