1.Middle-aged and elderly people over 50 years old: Immunity decreases with age, and the incidence rate increases significantly.
2.People with low immunity: Such as HIV patients, cancer patients or people taking immunosuppressants for a long time.
3.Those who have not been vaccinated: People who have not been vaccinated against chickenpox or shingles are at higher risk.
