The main manifestations of novel pneumonia are still fever and dry cough, some infected people may have malaise, and a few patients may have a stuffy and runny nose. However, as the number of infected people increases, digestive symptoms such as diarrhea and abdominal pain may appear. Do not panic if you have diarrhea, but promptly check whether it is caused by the new coronavirus infection.
