The main reason why Xiaotangshan Hospital was able to achieve zero infections among healthcare workers was because the hospital did a particularly good job of physical protection. Doctors in contact with patients will wear protective clothing, shoe covers, goggles, masks, in unnecessary time doctors and patients will have a certain distance between the communication, from all aspects as far as possible to ensure the safety of health care workers. After contact with the patient also need to carry out a number of disinfection process, to avoid the virus residue in their own body. And the hospital also specially formulated a series of regulations, medical staff to the ward route, medical staff of personal protection measures, medical staff of other work arrangements, etc., need to strictly in accordance with the provisions of, otherwise there will be corresponding punishment. In all aspects of the situation to avoid as much as possible to avoid the health care workers to come into contact with the virus, but also to do more than a thousand health care workers were not infected with the SARS virus, peacefully through the special period. At the same time, the planning of Xiaotangshan Hospital is also very scientific, with different patient zones, as well as different departmental zones, all very clear, and the treatment of patients will be based on the patient's own situation to carry out specialized and effective treatment programs. The process of treatment with scientific planning, can reduce the number of medical personnel contact with the patient, specialized departments of medical personnel contact with the corresponding symptoms of the patient, but also has a certain protective effect. And in order for healthcare workers to be more vigilant, there is also the provision that if a healthcare worker is infected, he or she is directly removed from his or her position. This provision is both a protection for everyone, but also a strict requirement for everyone, so that every health care workers can be more careful with their own life safety, to avoid the health care workers have the mentality of fluke. I think it's very successful that Xiaotangshan Hospital has been able to achieve zero infections among healthcare workers, and I hope that the new hospitals for this new type of pneumonia will be able to do the same.
