Chickenpox is an acute infectious disease, and prevention of the infection mainly involves the following three aspects:

First, control the source of infection. Patients with chickenpox are the only source of infection, so they should be isolated until all the chickenpox blisters have crusted over.

Second, cut off the transmission route. Avoid close contact with chickenpox patients, prevent airborne droplet transmission, and avoid contact with items contaminated with the chickenpox virus.

Third, protect susceptible populations. Chickenpox is highly contagious and generally susceptible in the population. Infants over one year old can be vaccinated with the chickenpox vaccine for prevention. Regular exercise, nutritional enhancement, physical strengthening, frequent hand washing, and maintaining ventilation in indoor environments are also advisable.
