There is a new positive case 1 case in Guangzhou, which was inadvertently exposed to infection when collecting garbage. What is the epidemic trajectory of infected people?

Recently, COVID-19 has been under strict control. Although there has been another outbreak in the past, the affected area is still very small in general, and only some areas keep showing new cases. However, in any case, the COVID-19 epidemic has been well controlled in China. Compared with other countries, China is probably the least harmful. Recently, however, there has been another positive case in Guangzhou. When she was collecting garbage, she accidentally exposed herself as an infected person. Moreover, by understanding her experiments and information, we conducted follow-up investigation and nucleic acid detection on close contacts and residents in key areas. It is judged that she has some connection with the confirmed cases imported from abroad, but the risk of community transmission is relatively low. Her main job is in the hotel, and then she is engaged in delivering meals and cleaning rooms. So her trajectory is very simple, that is, on the way from home to work in the hotel, she has never been anywhere else, so we just need to check these people and other close contacts, and then get to know the contacts of these close contacts and their life contacts properly. COVID-19 is always the most important. After all, he is very infectious. If he is not careful, it will spread to far away places, and many people will become indirect infections and infect more people. Therefore, patients with COVID-19 must be strictly controlled, and those who come into contact with him must be tested for nucleic acid in time, and then quarantined regularly to protect COVID-19 from proliferation. Of course, this behavior is also to understand the flow trajectory of infected people, so as to better check and manage. After all, COVID-19 may face the situation of variation now, so we must be careful not to let our guard down, even if it is a case, we must understand all her processes.
