C-level close contact isolation policy

Class C close contacts generally refer to the classification of people who have been exposed to novel coronavirus or infected people in the prevention and treatment of epidemic situation in novel coronavirus, including people who have lived in high-risk areas within 14 days.

Novel coronavirus is an infectious virus. Acute infectious pneumonia can occur after infection, which is harmful to human body. In order to better prevent novel coronavirus, according to the contact history with novel coronavirus, it is divided into five categories: A, B, C, D and E.

Among them, the classification of Class C close contacts includes not only those who have lived in high-risk areas within 14 days, but also key personnel who may be exposed, those who have had contact with confirmed patients, staff of fever clinics and all other suspicious personnel.

The health code of class C close contacts is generally yellow, so isolation measures should be taken, and nucleic acid detection should be carried out regularly during the period. Even those with negative nucleic acid test should be quarantined for at least 14 days according to the local epidemic prevention requirements in novel coronavirus. If you have symptoms such as fever, fatigue and dry cough, you should report them in time, and the CDC will transport them to designated hospitals for isolation treatment through closed loop.

Class AB contacts in COVID-19

Class A contacts refer to confirmed patients. Refers to the contact with COVID-19 patients, patients who are positive by nucleic acid antibody test are diagnosed as COVID-19 infection. This patient has been infected with COVID-19 virus, which is contagious, so it should be handled in strict accordance with the quarantine policy.

Class B personnel refer to suspected patients. There is a possibility of infection after contact with COVID-19 patients, but it is not positive, but the related clinical symptoms belong to high-risk groups, and further inspection and isolation are needed. For example, some recessive infected people may be positive in the later examination.
