Influenza is a rapidly spreading and highly infectious human respiratory infectious disease caused by influenza viruses, which can cause huge loss of life and property on a global scale. The World Health Organization has prioritized the development of point-of-care testing (POCT) for respiratory viruses. The rapid and accurate diagnosis of influenza-like patients by POCT is of great significance for preventing and controlling the spread of influenza virus and reducing the occurrence and development of severely ill patients. Influenza POCT based on immunology is fast, simple but low sensitivity. Influenza POCT based on nucleic acid detection is convenient and quick, which makes up for the shortcomings of low sensitivity of immunology POCT. In the future, through optimization of cost-effectiveness, it can be applied in a large number of clinical immediate testing environments. This article summarizes the POCT methods that are currently being applied and developing diagnosis of influenza viruses.
