Management and Treatment of Mumps
Mumps is a self-limiting viral illness requiring primarily supportive care, with no specific antiviral treatment available; management focuses on symptom relief, monitoring for complications, and implementing strict isolation precautions to prevent transmission. 1, 2
Acute Management
Supportive Care
- Analgesics and antipyretics for fever and pain control
- Adequate hydration to prevent salivary duct obstruction
- Soft diet to minimize discomfort from parotitis
- Rest during the acute phase
Isolation Precautions
- Isolate patients for 5 days after onset of parotitis to prevent transmission via respiratory droplets
- Implement droplet precautions in healthcare settings
- Exclude from school/work during the infectious period
Monitoring for Complications
While mumps is generally self-limiting 1, serious complications require vigilance, particularly in adults where complications are more common 2:
Neurological Complications (Monitor Closely)
- Aseptic meningitis (4-6% of cases): typically mild but requires evaluation if severe headache, neck stiffness, or altered mental status develops 2
- Meningoencephalitis: can cause permanent sequelae including paralysis, seizures, cranial nerve palsies, hydrocephalus 2
- Transverse myelitis: rare but documented; presents with sensory-motor deficits; responds to high-dose pulse steroids 3
- Sensorineural deafness: sudden onset, may be bilateral and permanent; occurs in approximately 1 per 20,000 cases 1
Reproductive Complications
- Orchitis in postpubertal males (20-38% of cases): typically unilateral; sterility is rare despite high incidence 1, 2
- Oophoritis in females: less common than orchitis
Other Complications Requiring Intervention
- Pharyngolaryngeal edema with airway compromise: rare but potentially lethal; responds to systemic steroids, though tracheotomy may be necessary in severe cases 4
- Pancreatitis: supportive management
- Myocarditis: requires cardiac monitoring and supportive care 5
- Splenic abscess: extremely rare; suspect if left upper quadrant pain develops; requires parenteral antibiotics 5
- Parotid pustular abscess: rare; managed with continuous antibiotics without surgery 6
- Bilateral outer retinitis: devastating complication causing retinal necrosis; requires systemic steroids and potentially hyperbaric oxygen therapy 7, 8
Specific Treatment Considerations
Steroid Therapy
Systemic corticosteroids are indicated for specific complications:
- Pharyngolaryngeal edema with airway compromise 4
- Acute transverse myelitis (high-dose pulse steroids show significant improvement) 3
- Bilateral outer retinitis (though response may be suboptimal; consider hyperbaric oxygen) 8
Pregnancy Considerations
- Mumps in first trimester increases risk for fetal death 2
- No association with congenital malformations 2
- Supportive care only; no specific interventions alter outcomes
Prevention and Post-Exposure Management
Vaccination Status Assessment
Persons are considered immune if they have: 2
- Documentation of physician-diagnosed mumps
- Laboratory evidence of immunity
- Documentation of live mumps vaccine on or after first birthday
- Born before 1957 (though this doesn't guarantee immunity during outbreaks)
Post-Exposure Prophylaxis
- No effective post-exposure prophylaxis exists for mumps (unlike measles)
- Unvaccinated exposed individuals should receive MMR vaccine, though this will not prevent disease from current exposure
- During outbreaks, consider third dose of MMR for high-risk populations identified by public health authorities 9
Outbreak Control Measures
- Mandatory exclusion and vaccination of susceptible individuals in institutional settings 2
- Healthcare workers lacking immunity should be excluded from day 7 after first exposure through day 21 after last exposure 2
- Exclude susceptible students/workers for 3 weeks after rash onset of last case 2
Common Pitfalls to Avoid
Assuming birth before 1957 guarantees immunity during outbreaks: Consider MMR vaccination for healthcare workers born before 1957 without serologic evidence of immunity 2
Missing serious complications: Maintain high index of suspicion for neurological, cardiac, and ophthalmologic complications, particularly in adults
Delaying steroid therapy for life-threatening complications: Pharyngolaryngeal edema and transverse myelitis require prompt steroid administration
Inadequate isolation: Failure to implement proper droplet precautions can lead to nosocomial transmission
Overlooking abdominal pain: Consider splenic abscess or pancreatitis if abdominal symptoms develop 5
Laboratory Confirmation
Serologic confirmation is preferred over clinical diagnosis alone: 2
- Mumps IgM antibody (positive test confirms diagnosis)
- Significant rise in IgG antibody between acute and convalescent titers
- Viral isolation from clinical specimen
Clinical diagnosis alone is unreliable as parotitis has multiple infectious and non-infectious causes 2.
