Infants can get mumps. Mumps is mainly caused by mumps virus infection. Human is the only host of mumps virus, which is mainly spread through droplet transmission, and the main manifestation of infection is parotid gland enlargement accompanied by fever. Infants are susceptible to the mumps virus because of their weak immune system and immune deficiency, so they may get mumps. Vaccination is the most favorable measure to prevent mumps infection in infants. At the same time, you should also try to avoid letting infants enter crowded public places and wear masks when going out to prevent disease infection. If infection occurs, it should be treated by a doctor, and isolation measures should be taken to prevent the child from infecting other people, and long-term immunity can be obtained after the disease is cured. If an infant develops symptoms of mumps infection such as enlarged and painful parotid glands, he or she should seek medical attention in a timely manner and should not self-medicate to avoid delaying the condition, but should receive proper treatment under the guidance of a doctor.
