Abstract:
Mumps has re-emerged as an infection in the developed world. Its epidemiology has changed, with the majority of cases now primarily affecting adolescents and adults. While mumps is easily suspected if parotitis is present, parotitis is absent in 10%-30% of symptomatic cases. Mumps is a systemic infection with a variety of extra-parotid complications. In Australia, mumps diagnosis is confirmed by antibody testing and reverse transcriptase-polymerase chain reaction techniques. Suitable specimens for testing are serum, saliva, urine and cerebrospinal fluid. Treatment is generally supportive, although intravenous immunoglobulin therapy may have a future role in mumps management. Interferon alpha-2b treatment may be considered specifically for mumps epididymo-orchitis. Mumps vaccine is included in the measles-mumps-rubella (MMR) vaccine. In Australia, this vaccine is routinely administered at the ages of 1 and 4 years. Serious reactions to the mumps components of the MMR vaccine are rare.
Insights
Mumps is re-emerging in developed countries, mainly affecting adolescents and adults. Diagnosis involves antibody and PCR testing, with supportive care as primary treatment, though new therapies show promise.
Area of Science:
- Virology
- Epidemiology
- Immunology
Background:
- Mumps re-emergence in developed nations, shifting epidemiology to adolescents and adults.
- Parotitis is absent in 10%-30% of symptomatic mumps cases, complicating clinical suspicion.
- Mumps presents as a systemic infection with potential for extra-parotid complications.
Purpose of the Study:
- To outline current diagnostic approaches for mumps in Australia.
- To review treatment strategies for mumps, including supportive care and emerging therapies.
- To discuss the role and safety of the measles-mumps-rubella (MMR) vaccine in mumps prevention.
Main Methods:
- Diagnostic confirmation via antibody testing and reverse transcriptase-polymerase chain reaction (RT-PCR).
- Collection of specimens including serum, saliva, urine, and cerebrospinal fluid.
- Review of existing literature on mumps treatment and vaccination protocols.
Main Results:
- Mumps diagnosis relies on serological and molecular assays.
- Supportive care is standard; intravenous immunoglobulin and interferon alpha-2b show potential for specific complications.
- The measles-mumps-rubella (MMR) vaccine is effective and safe, with rare serious reactions.
Conclusions:
- Mumps requires vigilant diagnosis beyond parotitis, utilizing serological and molecular methods.
- While supportive care is primary, targeted therapies may improve outcomes for severe mumps manifestations.
- MMR vaccination remains crucial for controlling mumps outbreaks, with a favorable safety profile.
