The Austrian city of Klagenfurt indefinitely suspended its bus services Wednesday after a case of measles was detected in one of the drivers.
"All bus traffic is suspended until further notice in order to prevent infection," the city's KMG public transport operator announced.
The company runs all public transport in the southern city of 100,000 inhabitants, which is also the state capital of Carinthia.
It took the unusual measure after it was revealed that one driver had been diagnosed with measles on 3 April.
