NAPA COUNTY (BCN) — The first dead bird this year to test positive for West Nile Virus was found in the City of Napa on July 31, the county’s Mosquito Abatement District said.
The presence of the virus in the bird, an American crow, was confirmed Wednesday, the District said.
The positive test should remind residents to take precautions to protect themselves and their families from mosquito bites, Napa County Public Health Officer Dr. Karen Relucio said.
The virus is transmitted to humans and animals by a bite of an infected mosquito. The risk of serious illness to most people is low, and less than 1 percent of infected people will develop severe illness, health officials said.
People 50 and older have a higher chance of getting sick and developing complications, health officials said.
Applying insect repellant, wearing long sleeves and other protective clothing outdoors at dawn and dusk and draining standing water on property where mosquitoes breed reduce the chance of contracting the virus.
