Early symptoms of novel coronavirus may include sneezing. Since novel coronavirus is a virus transmitted through the respiratory tract, the first to enter the respiratory tract is the nose and throat. If the nose and throat are infected with the novel coronavirus, some people will have a runny nose, sneezing, or even a sore throat. But it is not that sneezing is novel coronavirus infection, because many diseases can be sneezed, such as cold, allergic rhinitis, and allergic pharyngitis, all of which can have sneezing symptoms. Therefore, if you want to diagnose novel coronavirus, you need to check the nucleic acid of respiratory secretions, and if the nucleic acid is positive, only then can you confirm the diagnosis of novel coronavirus infection.
