One pregnant woman found to have Zika after DC testing error
District of Columbia officials say a pregnant woman tested positive for the Zika virus after initially being told she tested negative last year.
The city was forced to send more than 400 samples to the Centers for Disease Control and Prevention for retesting after a scientist made a math error.
The city's Department of Forensic Sciences announced Monday that it shared the disturbing news with a woman who was pregnant at the time of her test. Another woman and man also tested positive, after first being told they were negative. The CDC said 394 samples tested negative and results were inconclusive for 26 samples.
The city released no information about the impact on the woman's pregnancy. Zika can cause severe birth defects, including babies born with abnormally small heads.
