When infected with novel coronavirus, there is a very small chance that frequent sneezing will occur, and most patients only have mild sneezing symptoms. The main symptoms of novel coronavirus infection are fever, dry cough and malaise, but upper respiratory symptoms such as runny nose and sneezing are rare, so frequent sneezing is unlikely to occur. Novel coronavirus is the main way of transmission through respiratory droplets and close contact. In addition, contact with objects contaminated with the virus may also cause some infection. If there is any abnormality in the body, it is recommended to go to the hospital for prompt treatment. If you come into contact with a patient with novel coronavirus or a carrier of novel coronavirus and the nucleic acid test is positive, isolation and symptomatic treatment are required. If sneezing is frequent and the nucleic acid test is negative, it is likely that the symptoms are caused by upper respiratory tract infection or allergy, and relevant tests, such as routine blood test and IgE blood test, are needed.
