US authorities fear the spread of a dangerous disease.
Three US airports will begin screening passengers arriving from China. The goal is to identify potential carriers of the dangerous virus, which was first detected in the city of Wuhan. The virus caused the death of two people.
The US centers for disease control and prevention (CDC) said the screening will be conducted at airports in San Francisco, Los Angeles, and New York, and primarily concern passengers who arrived from Wuhan or made a transfer in that city.
They will be invited to a separate room, where they will be asked to fill out a special questionnaire and check for symptoms of fever. If necessary, passengers will be sent to the hospital for additional checks.
No treatment methods have yet been developed for those infected with this virus.
