Parents in kindergarten suddenly come from high-risk areas and find positive. What should I do?

Please tell the truth. If parents have traveled to and from high-risk areas, or have crossed the travel track of people who are positive for nucleic acid testing, they should truthfully report to the class teacher, isolate themselves, and go to the epidemic prevention department for nucleic acid testing. Those who are negative will give a copy of the nucleic acid test and health code to the kindergarten. If they can't provide negative information about nucleic acid testing, their children must receive nucleic acid testing at the first time and be observed in isolation. Those who conceal and fail to report, resulting in adverse consequences, will be investigated for legal responsibility by the relevant departments.
