Not quite "dragged", but this happened to a friend of mine.
Her country was on the safe (no isolation) list when her plane landed in China, and she then boarded a long distance, overnight train.
Her country then announced their first positive case.
When she left the train, two men with hazmat suits and a van were on the platform to meet her. They took her to an isolation hotel room with an alarmed door. (Not an actual lock, as I understand, so she could leave if there were a fire. But an alarmed door.)
