Neocoronavirus refers to the new coronavirus pneumonia. In the initial stage of infection with novel coronavirus pneumonia, the symptoms displayed vary from patient to patient due to differences. Most patients will mainly have symptoms such as dry cough, fever and malaise, and some patients may not have any obvious symptoms. In addition, due to the individual differences between different patients, there are also patients who may show symptoms such as chest tightness, itchy throat, sore throat, muscle pain, nasal congestion, runny nose, and loss of sense of taste. However, these symptoms are not unique to new coronavirus pneumonia and may occur in most diseases, so it is not possible to determine whether or not you are infected with the new coronavirus through these symptoms. If you show the above symptoms, and there is a high probability that you have been in contact with a person infected with the new coronavirus, you should go to the hospital for a nucleic acid test to find out whether you have been infected. Note: On December 26, 2022, the National Health Commission announced that the terms “new coronavirus pneumonia” and “new coronavirus pneumonia” were renamed to “new coronavirus infection” in this article.
