Cough with sputum without fever is generally not a novel coronavirus infection. Cough with sputum without fever can be seen in a variety of respiratory diseases, such as the common cold, which can present with cough with sputum, bronchitis, pneumonia, bronchiectasis, and tuberculosis, which can present with clinical symptoms of cough with sputum without fever. Novel coronavirus pneumonia can present with a cough with sputum, but the early manifestations of novel coronavirus infection causing new coronavirus pneumonia are mainly a dry cough, often accompanied by symptoms of fever and malaise, and, as the disease progresses, chest tightness and shortness of breath, even dyspnea. Therefore, if there is no epidemiological history, i.e., no exposure to the case in question, the presence of cough with sputum is considered a general respiratory disease and not a new coronavirus infection causing neo-coronavirus pneumonia.
