Dalian/kloc-close contacts under 0/4 years old go to the hotel for centralized isolation. Do they need to do nucleic acid to accompany their parents every day?

If family members live with isolators, in order to eliminate the risk of infection, family members also need to carry out nucleic acid testing. In addition, once the nucleic acid test of the isolator becomes positive and the diagnosis is made, the family members must also carry out nucleic acid test just in case.
