Hawaii state health officials report investigating a probable case of mumps in South Kona on the Big Island.
The individual is unvaccinated with no history of travel or exposure to visitors, with suspected secondary transmission to an unvaccinated household contact.
Health officials note that while this case is still under active investigation, at this time they have not identified a confirmed linkage to a school setting.
Mumps is an acute viral illness characterized by nonspecific prodromal symptoms (low-grade fever, myalgia, anorexia, malaise, headache) followed several days later by pain, tenderness, and swelling in one or both parotid salivary glands. Swelling usually peaks in 1 to 3 days and then subsides during the following week. Patients may also present with nonspecific symptoms or with primarily respiratory symptoms or may be asymptomatic. Mumps can occur in a person who is fully vaccinated, but vaccinated individuals are at much lower risk for mumps and mumps complications.
The mumps virus is transmitted person to person through direct contact with saliva or respiratory
droplets from a person infected with mumps. The incubation period is usually 16 to 18 days, with a range of 12 to 25 days after exposure. The infectious period is considered from 2 days before to 5 days after the onset of parotitis, although virus has been isolated from saliva as early as 7 days prior to and up to 9 days after parotitis onset.
