Based on the analysis of available cases, some patients may present with sneezing and runny nose after infection, but it is not very common. The first and main symptom of novel coronavirus infection is fever, which may be accompanied by malaise, dry cough and lack of energy and loss of appetite. However, these symptoms are very similar to those of the common cold and influenza, with no significant differences, so the diagnosis cannot be confirmed based on symptoms alone. If the patient has a history of suspected exposure or a history of traveling or living in Hubei and other virus-endemic areas, it is recommended that he or she first isolate himself or herself at home after the appearance of mild sneezing and runny nose symptoms. If symptoms gradually worsen within a few days and manifestations such as fever and difficulty in breathing appear, you need to seek medical attention at fever clinics around the country.
