Mosquito Sample Test Positive for West Nile Virus in Norfolk

Last Updated: August 9, 2024

NORFOLK Va. – The Norfolk Department of Public Health has detected the first West Nile Virus
(WNV) activity of the season in the city of Norfolk. One mosquito sample has tested positive for West
Nile virus. The sample was collected at the Cedar Grove Cemetery located at 238 East Princess Anne
Road. The Division of Vector Control is conducting mosquito control operations in the adjacent area,
including treatment of standing water. Fogging operations will be conducted when weather permits, as
well as additional surveillance activities.

West Nile Virus is spread to people by the bite of an infected mosquito. Mosquitoes become infected
when they feed on infected birds, and then spread WNV to people and animals by biting them. Most
people infected by WNV do not have any symptoms. When WNV develops into illness, symptoms can
include a mild fever, headache, body aches, vomiting, or diarrhea. Serious illness is rare, but more
severe symptoms can occur including high fever, severe headache, nausea and vomiting, stiff neck,
muscle weakness, confusion, disorientation, paralysis, seizures, or coma. Death occurs in about 10% of
persons with serious illness.

Residents are advised to take these preventive steps to help protect themselves and their families from
mosquito-borne illnesses:

• Avoid mosquito bites by using insect repellents when outdoors in mosquito-infested areas.
Always ensure that you follow directions on the label.
• Wear clothing that is long, light, and loose.
• Home doors and windows should be well-screened to prevent entry of mosquitoes.
• It is important to eliminate mosquito breeding sites from yards by removing old tires, buckets,
tubs, toys, and other items that hold rainwater. Dump ornamental containers (e.g., bird baths) on
a weekly basis, or use mosquito larvicide pellets or dunks periodically to treat larger containers
(e.g., ornamental ponds, stagnant swimming pools).
• Clean roof gutters and downspout screens.
