In novel coronavirus pneumonia, most people present with respiratory symptoms, mainly pneumonia, and a few may have conjunctivitis and diarrhea. In severe critical cases, there are more complications, such as acute respiratory distress syndrome ARDS, which is the main cause of respiratory distress in severe critical cases, even if it is life-threatening. There may also be heart damage, arrhythmias and myocardial damage, and there may be heart failure and kidney damage in a very small number of critically ill cases. In many critical cases there is renal failure at the end stage, requiring renal replacement therapy, and there may be encephalitis, but of course these are very rare. The most common is still respiratory failure, i.e. acute respiratory distress syndrome. In the rare long-term hospitalized patient, there may also be hospital-acquired infections, i.e., nosocomial infections, and nosocomial infections tend to be bacterial, especially drug-resistant bacterial infections. Novel coronavirus pneumonia is a viral infection and antibiotic treatment is not advocated, but in cases of prolonged hospitalization combined with nosocomial infections, stronger antibiotic treatment may be necessary.
