Acute bronchitis is an acute infectious disease of the respiratory tract that requires timely treatment. If not treated promptly, it may turn into chronic bronchitis or cause other complications, which are detrimental to health. Therefore, it is important to detect and treat the disease early. If the infection is due to Streptococcus pneumoniae or diplococcus, intravenous drip of penicillin antibiotics can be administered. During the acute phase, it is also advisable to choose antipyretic medications, as well as medications to dilute sputum and relieve bronchial smooth muscle spasms for symptomatic treatment. Early detection and treatment can help prevent complications.
