Hallmark of infection is swelling and inflammation of one or both of the parotid glands (parotitis).
More serious complications of mumps, such as meningitis, encephalitis, and orchitis, can occur in the absence of parotitis, potentially delaying the accurate diagnosis of the disease.
Diagnosis can usually be made based on the characteristic clinical features of parotitis and prodrome alone. Laboratory diagnosis is based on serological or salivary confirmation, detection of viral nucleic acid, or isolation of the virus from body fluids.
Treatment is symptomatic, and the disease can be prevented largely by routine vaccination.
The mumps vaccine is used almost universally in developed countries, as part of MMR (measles, mumps, and rubella) vaccine. Sporadic outbreaks have occurred in highly vaccinated populations, leading to suggestions that the vaccine’s efficacy may not be as high as originally thought and that vaccination policy should be reviewed, perhaps to include 3 doses.
Mumps is an acute systemic infectious disease caused by an RNA paramyxovirus. It is spread by respiratory droplets, and, before the advent of the mumps vaccine, it affected school-aged children commonly. Classically, mumps causes swelling of the parotid glands; the involvement of other salivary glands, meninges, gonads, and pancreas is also common.
