CHIBA--A man with measles worked at Narita Airport between April 22 and 26, and prefectural officials are urging travelers who used the airport during that period to check for possible infections.

The prefecture said on April 30 that the man in his 20s worked at Terminal 2 but did not disclose his company. Sources said he dealt directly with customers in the service industry.

His working shifts were from 7 a.m. to 10:30 p.m. on April 22, from 2:30 p.m. to 10:30 p.m. on April 24, and from 6 a.m. to 6:30 p.m. on April 26.

The prefecture said it is possible that people who used Terminal 2 could have been infected even two hours after his shifts ended. It has asked such travelers to call medical institutions in advance of visits if they develop fevers or rashes.

According to the prefecture, the man had a fever close to 39 degrees on April 23. After a rash appeared on April 27, he went to a medical institution in Narita, Chiba Prefecture, and was diagnosed as having measles on April 28.

He commuted by car and did not use public transportation.

The prefecture has been checking about 40 employees who worked close to him and is trying to determine where he became infected.
