Acute bronchitis has a relatively high incidence rate in clinical settings, often occurring in populations with lowered immune functions. Typically, acute bronchitis caused by bacterial infection does not have the potential to spread. However, acute bronchitis resulting from viral, mycoplasma, or chlamydia infections can be transmitted through respiratory droplets, especially among individuals with compromised immune systems. If these individuals come into contact with others infected by such viruses or pathogens, transmission is likely to occur. Therefore, once acute bronchitis is accurately diagnosed, it is crucial to administer timely anti-infection treatment to significantly reduce the chances of transmission.
