Mosquito Sample in Norfolk Tests Positive for West Nile Virus

The Norfolk Department of Public Health in Virginia has confirmed that a mosquito sample collected in the Edgewater/Larchmont neighborhood has tested positive for West Nile Virus. This is the first reported case of West Nile Virus activity in the city this year. In response to the detection, Norfolk’s Division of Vector Control has implemented several measures to combat the virus.

The main mode of transmission of the West Nile Virus is through infected mosquitoes. The insects become carriers of the virus after feeding on infected birds. While most individuals who contract the virus do not experience any symptoms, some individuals may develop mild symptoms, such as fever, headache, body aches, vomiting, or diarrhea. However, in rare cases, the virus can lead to serious illness, characterized by high fever, severe headache, nausea, vomiting, stiff neck, muscle weakness, confusion, disorientation, paralysis, seizures, or even coma. Approximately 10% of individuals with serious illness caused by West Nile Virus may experience a fatal outcome, according to the health department.

In order to prevent the spread of the virus and protect residents, the health department has provided several preventative measures. These include the use of insect repellents when outdoors in mosquito-infested areas, wearing long, light, and loose clothing to minimize exposure, and ensuring that homes are well-screened to prevent mosquito entry. Additionally, it is crucial to eliminate any potential mosquito breeding sites, such as old tires, buckets, tubs, or other items that hold rainwater. Regular maintenance, such as cleaning roof gutters and screens, is also recommended to reduce the mosquito population.
