The first symptom of novel coronavirus pneumonia is diarrhea alone in some patients, but this is relatively uncommon. According to the fifth edition of the Pneumonia Protocol for Novel Coronavirus Infections, the first symptoms of novel coronavirus pneumonia are usually fever, dry cough, malaise, and later may include dyspnea or other related symptoms. Viral nucleic acids can be found in the stool and anal swabs of infected patients, but further experimental evidence is needed to determine whether the novel coronavirus can be transmitted via the fecal-oral route and whether the virus is infectious in the stool. Some neo-coronaviruses cause diarrhea similar to general bacterial diarrhea, some of which may be very severe, such as the presence of watery stools, enteritis, or even bloody watery stools. There are no specific medications available for neocoronavirus, and attention to rehydration is needed for diarrhea. Whether feces and vomit are infectious or not needs to be further investigated. Respiratory transmission or close contact is the clearer route of transmission, while fecal and other routes of transmission need to be further investigated. The diagnosis of novel coronavirus pneumonia requires nucleic acid testing and epidemiological investigation to determine whether the infection is a novel coronavirus. Content source: Dr. You Lai
