The presence of cough and low fever is more commonly seen clinically as a manifestation of inflammation of the respiratory system. The body is invaded by such pathogens as viruses and bacteria due to a decrease in resistance due to such triggering factors as cold, rain, staying up late, and alcoholism. At this time, the inflammatory response in the body is strong and there are fluctuations in body temperature and even persistent low fever, accompanied by inflammation of the airway and exudation of inflammatory secretions that lead to coughing. The more common ones are acute upper respiratory tract infection, acute bronchitis, pneumonia, etc. Blood tests and X-rays or CT of both lungs can be taken to clarify the diagnosis. For treatment, you can choose some medications, such as blue scutellaria oral liquid, fishy grass syrup, and clearing fever and detoxification capsules. For viruses, ribavirin, oseltamivir, etc. can be given. For bacteria you can choose antibiotics, such as penicillin, amoxicillin, etc.
