After the U.S. temporarily halted all U.S.-bound flights of Afghan evacuees from overseas bases Friday in response to four evacuees testing positive for measles, the Virginia Department of Health announced that three Afghan refugees were diagnosed with measles in northern Virginia.

"Out of an abundance of caution, health districts in northern Virginia are informing people who were at various locations listed below during the specified time frames, that they may have been exposed to one of three people diagnosed with measles," the announcement said. "These individuals recently traveled from Afghanistan as part of the United States government’s emergency evacuation efforts"

The department of health listed possible exposure at Dulles Airport on Sept. 3, 4 and 8, at StoneSprings Hospital Center on Sept. 6 , Inova L.J. Murphy Children’s Hospital on Sept. 7 and 8, the Dulles Expo Center from Sept. 4-8, and at the Crowne Plaza Dulles Airport from Sept. 4-9.

The health department is coordinating efforts to reach those who were possibly exposed, according to the statement.

The U.S. has temporarily halted all U.S.-bound flights of Afghan evacuees from bases overseas after four evacuees tested positive for measles, White House press secretary Jen Psaki said at a briefing on Friday.

"Operation Allies' welcome flights into the United States have been temporarily paused at the request of the CDC, and out of an abundance of caution because of four diagnosed cases of measles among Afghans who recently arrived in the United States," Psaki said. "These individuals are being quarantined in accordance with public health guidelines, and the CDC has begun full contact tracing."

Psaki said all Afghans are required to be vaccinated for measles, mumps and rubella as a condition of entry into the U.S. and that those immunizations are being administered as refugees are received at domestic military bases. The White House is also exploring measures to vaccinate people while they are still overseas, she said.

"But it was again a step recommended by the CDC out of an abundance of caution given for measles cases," Psaki added.

National Security Council spokesperson Emily Horne has confirmed that U.S. citizens and permanent residents were among those on the second passenger flight to leave Kabul since the U.S. military withdrawal. There were also Americans and lawful permanent residents taken out of  Afghanistan on Friday "via overland passage," she said.

"Today the United States government facilitated the additional departures of U.S. citizens and lawful permanent residents both on a chartered Qatar Airways flight from Kabul and via overland passage to a neighboring country. The Qatar Airways flight held 19 U.S. citizens and the party traveling overland included two U.S. citizens and 11 lawful permanent residents," she said.

State Department spokesperson Ned Price previously confirmed that Thursday's flight had 10 U.S. citizens and 11 lawful permanent residents, or green card holders, on board.

A second Qatar Airways flight from Kabul landed in Doha at 7:29 p.m. local time, according to flight data, with an unknown number of foreign nationals on board.

The flight number for the Boeing 777 -- QR7277 -- was the same as Thursday's, the first flight out of Kabul since all U.S. personnel withdrew.
