Mumps can be transmitted to adults because it can occur at all ages, mostly in children, but also in adults. People who have not had mumps before, or who have not been vaccinated, may be at risk of developing the disease after contact with mumps patients, so it is important to manage mumps patients and isolate them. It is also important to protect yourself when in contact with patients by wearing a mask and washing your hands after handling them. In times of high epidemic, avoid going to crowded places, ventilate and disinfect rooms frequently, and vaccinate susceptible people.
