Fifth, personal perception of bronchitis patients due to viruses, bacteria, chlamydia pneumonia, mycoplasma and other infections caused by the most common is the case of patients infected with influenza virus. Elderly patients often suffer from bronchitis due to poorer resistance. Therefore, when coughing, coughing up sputum, fever and other symptoms, it is not recommended that patients take medication at home, so as not to delay treatment. We should consult the doctor in time to identify the cause of the disease and then carry out symptomatic treatment, such as anti-infection, cough, phlegm and so on.
