Should Foshan go back to Liuzhou for quarantine?

No need. Liuzhou's epidemic prevention policy is that people who come to Liuzhou from low-risk areas should be examined twice every three days and monitored at home. Foshan is a low-risk area, so there is no need to separate Foshan from Liuzhou. Infectious disease isolation refers to placing patients with infectious diseases and suspicious patients in designated places to temporarily avoid contact with the surrounding people, which is convenient for treatment and nursing.
