West Nile Virus (WNV)
There have already been some reported cases of WNV in Dallas County this year.
Here are some helpful facts:
1. More than 80% of people who are infected with the WNV show NO symptoms, and over 25% of the mosquito population in Dallas carry the virus. Which means you and your family may have already been infected without getting sick.
2. Only 20% of infected people will have mild flu like symptoms that disappear in a few days. Only 1% of these people go on to have severe symptoms requiring medical treatment due to severe neck stiffness, tremors, seizures and loss of consciousness. Most of these people are over 50 years of age and/or have a compromised immune system due to cancer, HIV or organ transplant.
3. If you believe you or your child has WNV that requires immediate hospitalization due to the above symptoms, contact your PCP or go to nearest emergency room.
Is there treatment?
There is no medication or treatment for WNV. In severe cases, patients receive supportive care of IV fluids, fever reducers, and anti-seizure medications when needed.
How is it spread?
It is only spread through mosquito bites and cannot be spread from person to person.
The 4 Ds of prevention:
1. DEET containing bug sprays, they need to be washed off once indoors.
2. Dress with long sleeves and pants when possible.
3. Dusk to Dawn: avoid being outside during high mosquito activity.
4. Drain all standing water around your home, no matter how small the amount.
Pediatric House Calls, doctor’s offices and urgent care clinics do not test for WNV. It is a very expensive specialized test that takes 3-5 days for results. Call the Dallas County Health department for testing facilities. Go to CDC.gov for more information on WNV.
