If he is in China, first he will be mandatorily stay in hospital until he is fully recover. After recovery he will be sent to a hotel with another 14-day quarantine. Second, his close contacts(family members, co-workers) will be quarantine in a hotel for 14 days. Third, his other contacts( neighbors, people wherever he met in a short time) will be asked to quarantine at home for 14 days. local government staff will be responsible to monitor and deliver food and goods during home-quarantine. Hospital treatment and mandatory hotel quarantine are free of charge ( very socialism haha). A great social loss for China but finally the situation is under control now.
