Mumps is an acute viral illness usually resulting in parotitis in approximately 30-40 percent of infected individuals. Other common manifestations include myalgia, anorexia, malaise, headache, and low-grade fever. Up to 20 percent of infections are asymptomatic. Transmission of mumps occurs through airborne transmission or direct contact with infected droplet nuclei or saliva.

Two cases of mumps were reported in Indiana in 2002. Both cases were laboratory confirmed by IgM serological analysis.

Because of the difficulty in distinguishing mumps from other forms of parotitis, IgM mumps-specific serologic testing is strongly recommended on all sporadically reported cases. The specimen should be drawn at least three days following onset of parotitis. Although Indiana has a relatively low number of mumps cases (Figure 1), medical providers should consider mumps diagnosis and serological analysis when parotitis of two days or longer has occurred.
