Human West Nile Virus Case Reported In Fairfax County

FAIRFAX COUNTY, VA—The first human case of West Nile Virus in Fairfax County this year has been confirmed by the health department. An adult from the northeastern part of the county was hospitalized and is recovering from the disease.

The case comes after Prince George's County, Md. confirmed its first human case of 2018 on Wednesday, Aug. 1. The health department says there's been an increase in West Nile Virus infected mosquitoes around the county early this summer. In recent years, other cases have followed when one human case is reported.

"West Nile virus is spread by the bite of an infected mosquito, said Dr. Benjamin Schwartz, director of epidemiology and population health at the Fairfax County Health Department. "With high levels of WNV in mosquitoes and the recent rains leading to even more mosquitoes, it’s important for residents of Fairfax County to take precautions to protect themselves and their families."

Many people get mild cases of West Nile Virus with symptoms like fever, headache and muscle aches that can last days to weeks. However, severe cases can lead to meningitis, encephalitis, paralysis and even death, and recovery can take months or years.

People ages 50 or older or those with suppressed immunity due to disease such as cancer or diabetes are most vulnerable to West Nile Virus. Anyone experiencing symptoms such as high fever, severe headache, stiff neck, confusion and lethargy should seek medical help immediately.

Residents are asked to prevent mosquito breeding on their properties by eliminating sources of standing water or using larvicide in the water. The health department offers mosquito inspection of yards from the by calling 703-246-8931, TTY 711.

Preventative tips to avoid mosquito bites include:

• Use a mosquito repellent that contains DEET, picaridin, IR3535 or Oil of Lemon Eucalyptus, making sure to follow label instructions.
• Wear long pants and long sleeves to cover exposed skin.
• Avoid areas where mosquitoes are especially common during peak biting times, particularly at dawn and dusk.
