Abstract

Abstract Since the identification of the first case of pneumonia of unknown cause in 2019, the COVID‐19 pandemic has spread the globe for over 3 years. As the most populous country in the world, China's disease prevention policies and response plans concern the health of the country's 1.4 billion people and beyond. During the course of the pandemic, scientific research has been accumulated and given evidence‐based support to the official guidance of COVID‐19 management. The National Health Commission of China have compiled, published, and updated a total of 10 versions of the “Diagnosis and Treatment Protocol for COVID‐19 Patients” to better inform clinical practitioners and staff to effectively screen, diagnose, manage, treat, and care for cases of severe acute respiratory syndrome coronavirus 2 infection. This paper compares and summarizes each version of the protocol in terms of etiology and epidemiology, clinical manifestation and diagnosis, treatment and nursing, disease control and management, presenting detailed changes, additions, deletions, and refinement of the protocols.
