The White House said the halt was recommended by the US Centers for Disease Control and Prevention after the four measles cases were diagnosed.
“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,” White House press secretary Jen Psaki told reporters.
She did not say where the cases were located. Flights of Afghans have been coming to the United States from military bases in Germany and Qatar. Many are operated by commercial carriers.
Psaki said the individuals found to have measles were being quarantined in accordance with public health guidance and that contact tracing had begun. She said arriving Afghans were required to be vaccinated for measles as a condition for their entry into the United States.
The vaccine for measles, mumps and rubella is currently being administered to Afghans at military installations in the United States, Psaki said. She added the administration is exploring measures to vaccinate people at overseas locations.
