What do you mean you can go to school in three days?

What do you mean by three inspections in three days? Honey, I'm happy to answer your question. Three times a day means checking nucleic acid three times a day. This nucleic acid needs to be converted into hours to calculate, that is, it takes 24 hours for the nucleic acid to be negative for three days. "Three tests every three days" means that nucleic acid is tested once a day (that is, every 24 hours) with an interval of 24 hours. Three tests in three days: complete three nucleic acid tests within three days (24 hours apart) and do a good job in self-health monitoring. Don't gather, drop in, go to crowded places for seven days, and take strict personal protection when going out.

"Three days and three inspections" is the abbreviation of nucleic acid detection frequency in epidemic prevention and control work in COVID-19. Simply put, it is to complete three nucleic acid tests within three days, and the time interval between the three nucleic acid tests shall not be less than 24 hours. If people from other places generally accept the imported risk to eliminate the epidemic situation of people coming to (returning to) xx, from now on, all people coming to (returning to) xx must hold the negative certificate of nucleic acid test within 48 hours, and implement the "three days, three inspections and three noes", that is, the nucleic acid is tested once a day for three days after arrival in xx, during which they will not eat dinner, have parties, go to crowded places or receive visitors. If there are other epidemics, please follow the opinions and information required by the local prevention and control departments.
