Mumps is contagious and mainly occurs in children and adolescents. Therefore, parents should take timely protective measures for children with mumps to prevent the infection from spreading to other children. Mumps is an acute respiratory infectious disease caused by the mumps virus invading the salivary glands. It is primarily transmitted through respiratory droplets, and its main clinical symptoms include fever and painful swelling in the parotid gland area, with body temperatures potentially reaching up to 40 degrees Celsius. Complications such as meningitis, meningoencephalitis, orchitis, oophoritis, and pancreatitis may also occur. For adults or children who have been infected with mumps before, the disease is not contagious again, as there are antibodies against the mumps virus in the body to resist the infection.
