Mumps in children is usually most severe 3-5 days after the onset of the disease, with variability depending on the specific condition of the patient. Mumps in children can be broadly divided into three phases according to the course of the disease: the incubation period, the prodromal phase, and the enlargement phase. The incubation period for mumps in children varies from 2-3 weeks after infection with the mumps virus. When an acute attack occurs, patients often have initial symptoms such as fever, headache, muscle aches, and loss of appetite. As the disease progresses, one or both parotid salivary glands may become painfully swollen after 3-5 days. Symptomatic treatment can be given to relieve the disease and shorten its duration. Commonly used oral medications include antiviral oral solution, acetaminophen oral solvent, and busulfan anti-inflammatory tablets. If the symptoms are more severe, physical therapy with infrared lamps can be used to accelerate the anti-inflammatory and anti-swelling effects. Mumps can now be prevented by two doses of mumps vaccine, usually in combination with measles, rubella and varicella vaccines.
