Nine new cases with positive nucleic acid test were reported in Qingdao. What is the source of infection?

Nine new cases with positive nucleic acid test were reported in Qingdao. From now on, the source of infection is the CT room of Qingdao Chest Hospital, which was originally examined by the person who diagnosed COVID-19, but it was not disinfected after the virus was diagnosed in COVID-19, which led to the infection of the people behind when doing CT examination. The person behind didn't realize that he was infected with COVID-19, and the virus in the molten slurry spread to his ward again, and then a series of infections occurred one after another, which also led to 9 patients with positive nucleic acid test in Qingdao.

We all know that 2020 is a memorable year for us. On the eve of the Spring Festival, a COVID-19 disturbed us, and the number of confirmed cases increased day by day, which made us feel uneasy. It is in Wuhan, the hardest hit area in COVID-19, that there are many confirmed COVID-19 patients. They don't have a ward in the hospital, so they can only isolate themselves at home. Think about it, what a painful thing it is. But later, the correct leadership of the country formulated corresponding policies. Wuhan Construction Committee also has a deep understanding of COVID-19. Medical personnel from all provinces and cities support Wuhan without fear of sacrifice, just to defend Wuhan and even support Wuhan in military hospitals.

So we all know that it is difficult to control the virus, so we are all trying to keep this balance, control the virus as well as possible and cut off the transmission route.

However, when we all thought that the virus had been eliminated, we fell into panic again because the CT examination room was not completely disinfected. Now the source of infection is clear, so be careful to protect yourself when dealing with the virus, that is, do a good job of self-protection, wear a mask when going out, control the distance of one meter when the trees are crowded, try not to talk to strangers and protect yourself.
