The contagion is strongest within two to three weeks after becoming ill. This disease is a respiratory infectious disease, mainly transmitted through airborne droplets, with children under five being the most susceptible to infection. Clinically, vaccination is primarily used to prevent the occurrence of the disease. Once infected, symptomatic treatment is needed, and one can also choose macrolide antibiotics, such as clarithromycin and erythromycin, for treatment.
