Cough and face fever are mainly seen in inflammatory reactions caused by infectious factors and non-infectious factors, as follows: 1. Infectious factors: Infectious factors are mainly due to decreased resistance and infection by bacteria, viruses and mycoplasma, which lead to inflammation of the respiratory tract, such as bronchitis and pneumonia, when the inflammatory reaction is stronger and causes fluctuations in body temperature, which raises the body temperature and leads to cough and face fever symptoms. 2.Non-infectious factors: If stimulated by allergens, such as cold air, pollen, mites, dust, the airway becomes highly reactive and triggers an acute attack of bronchial asthma, the patient will have cough and no sputum, and the cough will cause facial fever, congestion and edema when it is intense.
