Coughing is not necessarily a new coronavirus infection. There are many causes of coughing, including acute pharyngitis, allergic pharyngitis, acute upper respiratory tract infection, acute bronchitis asthma attack, and acute attack of chronic bronchitis, etc. Moreover, it is now the winter and spring season and coughing symptoms are very common. If you are not in an infected area and simply have a cough without a fever, there is no need to be overly alarmed for the time being. You can start with symptomatic treatment with oral antibiotics, phlegmolytic drugs or cough syrup of the proprietary Chinese medicine type. If you have a cough in an infected area and the coughing symptoms worsen within a week and are accompanied by chest tightness and difficulty in breathing, you should go to a designated hospital for further blood tests and chest CT to exclude new crown pneumonia.
