Hundreds of Zika virus samples retested

Washington D.C. public health lab officials recently confirmed that they are retesting hundreds of samples from people in the area for Zika virus over concerns about the accuracy of the original test results. In total, 409 specimens that originally tested negative, including 294 from pregnant women, were sent for retesting. Among the more than 200 samples from pregnant women that have been retested so far by a federal lab, nine were found to be positive.

As a reminder, Zika is primarily transmitted through the bite of infected Aedes aegypti or Aedes albopictus mosquito. However, the virus can also be transmitted through sexual intercourse. Many people infected with Zika virus won’t have symptoms or will only have mild symptoms. The most common symptoms of Zika include fever, rash, joint pain and conjunctivitis. Other symptoms may include muscle pain and headaches.

  1. If you are planning on vacationing, please review the CDC’s Zika Travel Notice page.
  2. If you are planning on traveling to an area that is known for Zika transmission, Use Environmental Protection Agency (EPA)-registered insect repellents.
  3. Even if you do not feel sick, travelers returning to the United States from an area with Zika should take steps to prevent mosquito bites for 3 weeks so they do not spread Zika to mosquitoes that could spread the virus to other people.
