What principles should be adhered to in the prevention and control work in COVID-19?

Four principles of standardized infection control in COVID-19: 1. Adhere to the principle of putting prevention first. All medical staff should take standard precautions, especially respiratory protection, and wear medical surgical masks. Patients, nursing staff and visitors entering medical institutions should also wear masks; Secondly, do a good job in process optimization, mainly to reduce the possibility of intersection between medical staff and patients, reduce the flow of personnel, and maintain the distance of 1 meter; Strengthening indoor ventilation and disinfection, especially natural ventilation, is a new trend. Medical institutions should consider improving the health literacy of the whole people in the reconstruction and expansion of hospitals, such as hand hygiene, wearing masks, paying attention to cough etiquette and keeping the distance between people. 2. Implement four early measures, namely, early detection, early diagnosis, early isolation and early reporting. Strengthen pre-diagnosis triage and fever clinic investigation, timely find confirmed cases, suspected cases and asymptomatic infected people, so as to find and report early. Complete the epidemiological investigation within 24 hours, and isolate the close contacts and asymptomatic infected persons. Divide the polluted area into the smallest units, thoroughly disinfect, cut off the transmission route and realize accurate control. In terms of treatment, we insist on concentrating the superior resources of patients and experts to greatly improve the treatment efficiency. In order to avoid the recurrence of positive accounting results, the discharged patients are required to stay at home or be isolated 14 days. 3 highlight key links to carry out risk assessment, focusing on prevention and control of key populations and key departments. Strengthen the prevention and control of hospital infection, treat patients by time, strictly manage visiting and accompanying personnel, avoid cross infection, strictly check the workflow of triage and fever clinic, and implement protective measures and health management and monitoring of medical staff. At the same time, pay attention to community prevention and control, especially the treatment process and control measures of community fever patients. 4. Strengthen support and support, organize and take the lead in expanding the scope of crowd testing, exchange and recognize national health codes, strengthen scientific research and international cooperation, and promote the research and development of reagents, vaccines and drugs; Local governments implement the responsibilities of party committees and governments, and dynamically adjust the risk level and response level.
