The CDC (Centers for Disease Control and Prevention) recently updated its guidelines concerning the testing of pregnant women who have a possible Zika virus infection or exposure. It must always be noted that most people with the Zika virus infection are either asymptomatic or have mild clinical symptoms. Mild clinical symptoms can be an acute onset of a fever, a rash, joint pain, and/or conjunctivitis.
There is new data suggesting that the virus can be detected in the blood and urine for 2 weeks after the infection begins. This testing of the urine and blood for the virus should be performed for:
- Symptomatic pregnant women in less than 2 weeks after the symptoms begin
- Asymptomatic pregnant women in less than 2 weeks after a possible exposure
After this 2-week window, blood testing should begin for the Zika virus IgM antibody, which the body makes in response to a new Zika virus infection. If this is found to be positive, there was definitely an infection and close fetal evaluation should begin.
As always, you should discuss the Zika virus problem with your health care provider so you can get the best possible care.
