The new positive case in Guangzhou is accidental contact infection when picking up garbage. How can we avoid this source of infection?

I believe everyone has seen the news, and another asymptomatic infected person has been found in Yuexiu District of Guangzhou. On September 4th, Yuexiu District, Guangzhou found COVID-19 nucleic acid positive 1 person during routine inspection of entry quarantine hotel staff. According to epidemiological investigation, the cleaner has been living in the hotel since August 30th and has never been home. The cause of this virus infection is accidental contact. Accidental exposure refers to the risk of direct contact between our bodies and the source of infection due to insufficient protection. How can we avoid this source of infection?

First, strengthen the management of staff in isolated hotels. The case of this infected person shows the negligence of the hotel in isolation, so it is strongly recommended that the hotel strictly require and manage the wine staff, and all details and processes should be implemented and standardized, and there should be no sloppy and convenient ideas and practices. Hotel staff is a high-risk group, so it is recommended to live in a hotel dormitory. How can hotel employees protect others if they can't even protect themselves?

Second, people engaged in high-risk jobs must pay attention to self-protection. People who work in Gree Hotel belong to high-risk groups. For the safety of yourself and others, you'd better stay in the hotel and don't walk around, so as not to increase the risk of virus transmission, because the epidemic situation in foreign countries is still grim, and people from abroad should be isolated in isolation hotels for 14 days, among whom there are likely to be virus carriers, so hotel staff must take preventive measures to avoid occupational exposure and expose themselves to danger.

Third, this infected person has been to many places before infection. The infected person has been to many places, first of all, he has been to residential areas, supermarkets and some surrounding public places, so it is necessary to investigate the epidemic track of the infected person and check the people who are in close contact with him. These people should be isolated in a centralized way, and they should be tested for nucleic acid every day. Therefore, all isolation points must strengthen the training of staff to prevent such incidents from happening again.
