The severity of the symptoms of novel coronavirus infection can be determined by the specific manifestations of the disease. General symptoms include fever, malaise, dry cough, and progressive dyspnea; some patients may have a mild onset of symptoms and may even have no significant fever. Severe symptoms include acute respiratory distress syndrome, septic shock, uncorrectable metabolic acidosis, and blood clotting dysfunction. In addition to the above symptoms, there may also be “atypical” symptoms, such as digestive system symptoms as the first manifestation, such as mild poor appetite, weakness, poor mental health, nausea and vomiting, diarrhea, etc.; neurological symptoms as the first manifestation, such as headache, etc. Content source: Dr. Yulai
