Abstract: Abstract: Novel coronavirus disease (COVID-19) pneumonia is a new infectious disease. Although great progress has been made in the clinical diagnosis, treatment and prevention in China, clinical treatment still faces many challenges. COVID-19 has special clinical symptoms and imaging manifestations, and the virus has special biological characteristics, which requires medical experts to continuously accumulate knowledge and experience, so as to further standardize the clinical diagnosis and therapeutic plan. In order to better guide the clinical practice, this paper summarized the general treatment information of 136 confirmed cases in Tianjin and discussed the experience of the early diagnosis, early warning of severe cases, anti-infection strategy and management of critical patient.
