Modern medicine in COVID-19 era

Coronaviral infections have been known for a long time; these viruses cause a number of diseases, not only in humans but also in animals. The current SARS-CoV-2 pandemic started in 2019 in China [1,2]. Discussions are ongoing about the timing of the first case, but there is no doubt that it was during the last quarter of 2019. The virus infection can be non-specific and asymptomatic, mildly symptomatic, and can cause severe pneumonia and acute respiratory distress syndrome (ARDS) requiring mechanical ventilation, as well as septic shock and multiorgan failure.
