Coronavirus disease 2019 (COVID-19) affects almost all the organs in the human body, especially the lungs and heart. As the number of patients recovered from COVID-19 continues to increase, increasing evidence suggests that a significant proportion of inpatients recovered from COVID-19 experience sequelae, and they mainly have the symptoms of respiratory and cardiovascular systems. For divers, the exercise tolerance and cardiopulmonary function after recovery from COVID-19 significantly affect their fitness to dive. Some organizations and institutions have released guidelines for the assessment of fitness to dive in divers after recovery from COVID-19. Herein, we briefly introduce the respiratory and cardiovascular sequelae and the assessment of fitness to dive in divers after recovery from COVID-19, and preliminarily provide the potential requirements for the assessment of fitness to dive in Chinese divers after COVID-19 based on the current conditions in China.
