There are 4 cases of nucleic acid positive people in Gansu who are all in the same restaurant. Of course, we can't just blame the restaurant for this incident. The reason for this is that the restaurant receives many guests every day. Of course, we don't know if this guest is a positive patient, so there are many defects in epidemic prevention.

If you own a restaurant, or contact many people every day, you must let them scan the place code. Only in this way can you see their whereabouts, and you need to remind them to do nucleic acid. After the itinerary code, you will attach the person who has done nucleic acid several times, or whether its nucleic acid is negative or positive. Of course, when you open a restaurant, you must also take out a person to the door to supervise these guests to do these jobs. And one by one, we should see clearly what their place codes are. Only in this way can we know which places they have been to and how many times they have done nucleic acid. Of course, opening a restaurant is actually a place with a lot of people. If we don't do some preventive requirements well, then our restaurant will definitely not be opened. The reason for being so rough is that if we have a positive case, many other guests will be isolated every day, of course.

Therefore, I must do this when I open a restaurant, and I must disinfect my tableware when I open a restaurant. If I don't disinfect my tableware, it will cause secondary infection. For example, this positive patient is asymptomatic, and his nucleic acid is still within 5 days or 6 days. If he doesn't do nucleic acid in recent days, he is likely to become a positive patient, so the tableware he used must also be infected.
