Acute bronchitis usually has a fever, and some patients may not have a fever.
Acute bronchitis is an acute inflammation of the bronchial tubes, which is common in children. When the body is infected by pathogenic microorganisms such as bacteria, viruses and mycoplasma, the immune system is activated and produces inflammatory factors to destroy the invading bacteria or viruses, etc. Inflammatory factors are endogenous pyrogens, which can stimulate the body and lead to fever.
Some patients with a mild inflammatory response may also not develop a fever.
Patients with acute bronchitis should go to the hospital and follow the doctor’s instructions to avoid worsening of symptoms.
