Fever and cough are most commonly associated with respiratory tract infections, or what is commonly referred to as colds. Fever and cough are not just a simple matter of reducing fever and stopping cough, but also a matter of identifying the source of the disease and treating the cause so that the disease can be cured in time. If a patient has fever and cough, accompanied by chills, headache, runny nose, sore throat, etc., it may be a symptom of cold, and then you can use some cold granules or cold and fever granules. If the patient has a more pronounced cough, accompanied by coughing and coughing sputum (yellow sputum in large amount), or even obvious sputum sound or croup, then it is necessary to consider infection of the lung. It is necessary to combine with imaging examinations such as chest X-ray and CT to determine the specific location of the lung lesion and the extent of inflammation, and then apply appropriate anti-inflammatory treatment with antibacterial agents. If the patient develops cough, cough with blood in the sputum, accompanied by low-grade fever, night sweats, and wasting, the possibility of pulmonary tuberculosis needs to be considered, which needs to be combined with chest X-ray and Mycobacterium tuberculosis examination, and patients with a clear diagnosis of pulmonary tuberculosis, especially those with cavitary tuberculosis, need to be treated in isolation. In conclusion, fever and cough are common symptoms. If the body temperature does not rise above 38.5℃ and there is no obvious discomfort such as coughing up pus, coughing up blood sputum, wheezing, etc., it is mostly an upper respiratory tract infection, so you can not worry too much, generally take physical cooling, pay attention to drink more water, eat more fresh fruits and vegetables, avoid spicy stimulation, pay more attention to rest, and enhance the body’s immunity and resistance.
