Quick answers

What is dengue fever?

Dengue fever is a mosquito-borne viral infection found in tropical and subtropical regions around the world. It causes flu-like symptoms and, in severe cases, can be life-threatening.

How is dengue fever typically transmitted?

Dengue fever is usually transmitted through the bite of an infected Aedes mosquito, primarily in tropical and subtropical regions.

What precautions can residents take to protect against dengue fever?

Residents can protect against dengue fever by using insect repellent, wearing long sleeves and pants, and eliminating standing water where mosquitoes can breed.

The brief

Virginia has confirmed its first locally acquired case of dengue fever. The Virginia Department of Health (VDH) announced the case in a Northern Virginia resident. The Washington Post, CBS19 News, Outbreak News Today, and WSLS all confirmed the news. The VDH is investigating the case, which is the first documented instance of the virus being acquired locally in Virginia.

The case is significant because dengue is typically transmitted through mosquito bites in tropical and subtropical regions. The VDH statement and the Washington Post article both note that the virus is usually contracted during travel to endemic areas. The VDH is working to determine how the individual contracted the virus locally. The VDH has not yet specified whether the case indicates a broader outbreak or if it is an isolated incident.

The agency is urging residents to take precautions against mosquito bites, such as using insect repellent and eliminating standing water where mosquitoes can breed. The VDH has not yet provided details on the patient's condition or treatment.
