Trends in the management of infectious disease under SARS-CoV-2 era: From pathophysiological comparison of COVID-19 and influenza

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has become a historic pandemic, and dealing with it is one of the most important aspects of infectious disease treatment today. SARS-CoV-2 has been found to have characteristic and powerful infectivity (ability to propagate) and lethality (severity). With influenza, primary influenza pneumonia from the virus itself is known to exist in addition to secondary bacterial pneumonia. With COVID-19, on the other hand, it is important to provide diagnosis and treatment while keeping acute respiratory distress syndrome and pulmonary edema (alveolar flood) from a similar cytokine storm, as well as severe angiopathy, in mind. The importance of complying with hand hygiene and masks in infection control remains the same as in previous general infection control measures and responses to influenza virus infections and others, but in the future, vaccination will likely be the key to infection control in the community.
