West Nile Virus (WNV)

West Nile Virus (WNV)

West Nile Virus (WNV) is a mosquito-borne virus that causes disease in humans, horses, and birds.  WNV spreads to people through the bite of an infected mosquito, and it can make people sick and even cause death. WNV affects humans and other animals but do not become contagious. Only mosquitoes can carry and spread WNV.  The best prevention is to wear insect repellent applied directly to all exposed skin.  Repellents should contain one of the following active ingredients: DEET, IR3535, Oil of Lemon Eucalptus (or PMD) or Picaridin/KBR 3023. To reduce the mosquito bites, remove stagnant water around your home and eliminate containers that might catch and hold water (even a bottle cap).
