The number of mumps infections rose by three Monday as the state records its highest number of cases in at least a decade.
The number of cases in 2017 is now up to 23 after three new cases were reported in East Honolulu and Waipahu, the state Department of Health reported.
Mumps is caused by a virus and typically begins with fever, headache, muscle aches, tiredness and appetite loss, followed by swollen salivary glands.
There is no specific treatment for mumps infection, but the Health Department recommends staying home from school or work for nine days after the onset of swelling to keep from spreading the disease.
