If you are on the same train as the infected person but not in the same compartment, there is no close contact between the two, and you have not been in close contact with the infected person’s peers, such as family members, colleagues, friends, etc., you are not a close contact and do not need to worry too much. During the high epidemic period, it is recommended that you rest at home as much as possible, do not go to crowded places, such as public baths, hot springs, theaters, Internet cafes, shopping malls, etc., minimize the number of public transportation rides, and wear a good mask when you go out to prevent infection with the disease.
