The DHS says that four passengers were taken from Dulles to a local hospital after enhanced screening raised alarms. DHS and the CDC don’t give further details. The two Northern Virginia hospitals closest to Dulles say they didn’t receive the patients. DHS and CDC aren’t able to explain the discrepancy. A person familiar with the screenings says a 13-year-old boy and his mother were taken to a hospital last Thursday after the CDC became concerned about their symptoms, and two other passengers were taken to a hospital over the weekend. The person was unable to name the hospital, and said that all four passengers apparently were released after further testing.
