Acute bronchitis is an acute inflammation of the bronchial mucosa, often caused by pathogenic microbial infections, as well as physical and chemical factors and allergic factors. Patients experience symptoms such as coughing, expectoration, fever, and wheezing. Generally, acute bronchitis does not require intravenous fluid treatment. It can be cured within two to three weeks through oral medication, such as oral anti-inflammatory drugs and oral cough suppressants and asthma relievers. However, in some cases, such as when symptoms are relatively severe, there is a bacterial infection, and oral medication is difficult, intravenous antibiotics can be considered for treatment.
