The precursors of mumps in children, often referred to as prodromal symptoms, may manifest in some children as fever, malaise, headache, and lack of appetite, while some patients, of course, do not have any uncomfortable symptoms. Generally, unilateral or bilateral painful swelling of the parotid glands occurs 1-2 days after the onset of fever. Some patients are given oral medication, while others may develop complications such as encephalitis, pancreatitis, orchitis or ovarian inflammation in the middle or late stages of the disease. Patients may develop clinical symptoms that require hospitalization, and after aggressive treatment, most patients will experience significant relief.
