With production resumptions increasing, Shenzhen has seen more and more workers returning from other places. To ensure people's health and relieve companies' pressure on workers' health management amid the novel coronavirus fight, the city has set up several health observation points for people returning to Shenzhen from areas hit harder by the virus.

Medical staff would record their health conditions at the observation points everyday, and they would be allowed to go back to Shenzhen's home for further quarantine once their throat swabs test negative.
