From December 2019, medical staff in Wuhan, China, were working with an increased workload and at risk of infection to treat patients with COVID-19 infection. Up to February 18th, more than 30,000 doctors and nurses from other provinces in China arrived in Hubei Province to assist in the treatment of patients. Local and national medical staff worked in isolation wards, fever clinics, the Intensive Care Unit (ICU), and other related departments. Some medical staff became infected with COVID-19 when they were treating infected patients. Chinese medical staff have shown professionalism and care, but the physical and psychological health of medical staff is at risk when working under such conditions, and anxiety and stress can also adversely affect sleep.
