Management of Mumps
Mumps management is primarily supportive care with strict isolation protocols, symptomatic treatment, and vigilant monitoring for complications, particularly in adults who face higher complication rates. 1, 2
Immediate Isolation and Infection Control
- Implement droplet precautions immediately upon diagnosis and isolate the patient for 5 days after parotitis onset, as patients remain contagious from 7 days before through 8 days after symptom onset 1, 2
- Educate patients and family members that transmission occurs through respiratory droplets and direct contact with saliva 1, 2
- This isolation period is critical even in vaccinated individuals, as breakthrough infections occur and 44% of cases in the 2006 U.S. outbreak occurred in persons with at least 2 vaccine doses 1
Symptomatic Treatment Protocol
- Provide acetaminophen or NSAIDs for pain and fever control to manage fever, headache, and parotid gland pain 1, 2
- Ensure adequate hydration and fluid intake, as parotitis makes swallowing uncomfortable and painful 1, 2
- Recommend soft foods and strict avoidance of acidic foods that stimulate salivary flow and worsen parotid pain 1, 2
- The disease is self-limiting, with most patients recovering without intervention beyond these supportive measures 2
Complication Monitoring by System
Neurological Complications (Monitor Closely)
- Watch for aseptic meningitis (occurs in 4-6% of cases): severe headache, neck stiffness, photophobia, or altered mental status 1, 2
- Monitor for encephalitis signs including seizures, paralysis, or cranial nerve palsies, which can cause permanent neurological sequelae 1, 2
- Assess for hearing loss, including sudden sensorineural deafness, which was historically a major cause of childhood deafness pre-vaccination 1, 2
Reproductive System Complications (Age-Dependent)
- In postpubertal males, assess for orchitis (occurs in up to 38% of cases): testicular pain and swelling typically developing 10 days after parotitis 1, 2, 3
- Reassure patients that sterility is rare despite the high orchitis incidence 1, 2
- In postpubertal females, monitor for oophoritis (ovarian inflammation) 1, 2
- Complications are significantly more common and severe in adults than children, making age a critical factor in monitoring intensity 2, 4
Other Systemic Complications
Special Intervention: Facial Nerve Involvement
- If facial nerve inflammation with weakness develops, initiate prednisone 1-2 mg/kg/day for 5-7 days followed by a 5-7 day taper 1, 2
- Provide eye protection to prevent corneal damage in patients with facial weakness 1, 2
- Reassure patients that complete recovery occurs in approximately 70-80% of cases within 3-6 months 1, 2
Post-Recovery Vaccination Considerations
- Adults born during or after 1957 without documentation of vaccination, laboratory evidence of immunity, or physician-diagnosed mumps should receive MMR vaccine after complete recovery 1
- A second MMR dose is recommended for adults in outbreak settings, postsecondary students, healthcare workers, or international travelers 1
- Do not administer MMR vaccine during acute illness; wait until recovery is complete 1
- Consider a third dose during outbreak settings for high-risk populations, though this is not routinely recommended by the CDC 1
Critical Clinical Caveats
- Only 30-40% of mumps infections produce typical acute parotitis; 15-20% are asymptomatic and up to 50% present with nonspecific or respiratory symptoms 1, 2
- This atypical presentation means mumps should remain on the differential for fever and malaise even without parotid swelling 2, 4
- Mumps can occur in highly vaccinated populations due to waning immunity, particularly in crowded environments like college dormitories 1, 5
- Women who develop mumps during the first trimester have an increased risk for fetal death 4
