When a novel coronavirus infects humans, patients may experience symptoms of sneezing. The virus mainly causes respiratory tract infection in humans. Most infected patients have fever, general malaise, and dry cough as the main manifestations, but a small number of infected patients may have nasal congestion, runny nose, diarrhea, mild nausea, mental depression, loss of appetite, nausea, vomiting, headache, panic, chest tightness, conjunctivitis, muscle aches in the limbs and lower back, and progressive respiratory distress in severe cases. Since the clinical epidemiological data are not yet perfect, the specific clinical manifestations of patients and their prognosis are yet to be analyzed and improved.
