Treatment of Mumps in Pregnancy
Mumps in pregnancy is managed with supportive care only—there is no specific antiviral treatment, and the mumps vaccine is contraindicated during pregnancy. 1
Primary Symptomatic Management
The cornerstone of treatment is symptom relief:
- Provide acetaminophen or NSAIDs for pain and fever control to manage fever, headache, and parotid gland pain. 1
- Ensure adequate hydration and fluid intake, as parotitis makes swallowing uncomfortable and painful. 1
- Recommend soft foods and avoidance of acidic foods that may stimulate salivary flow and worsen parotid pain. 1
Strict Isolation Requirements
Pregnant women with mumps require immediate isolation to prevent transmission:
- Implement droplet precautions immediately, as patients are contagious from 7 days before through 8 days after parotitis onset. 1
- Isolate for 5 days after onset of parotitis to limit spread to susceptible contacts. 1
- Educate family members about transmission through respiratory droplets and direct contact with saliva. 1
Monitoring for Complications
Pregnant women require vigilant monitoring, as complications can be more severe in adults:
Neurological Complications
- Monitor for aseptic meningitis (occurs in 4-6% of cases), characterized by severe headache, neck stiffness, photophobia, or altered mental status. 1
- Watch for signs of encephalitis, including seizures, paralysis, or cranial nerve palsies, which can cause permanent sequelae. 1
- Assess for hearing loss, including sudden sensorineural deafness. 1
Reproductive and Systemic Complications
- Monitor for oophoritis (ovarian inflammation) in pregnant women, which can present with pelvic pain. 1
- Watch for pancreatitis, characterized by severe abdominal pain, nausea, and vomiting. 1
Pregnancy-Specific Considerations
- Mumps in pregnancy may increase the risk of premature birth, though severe fetal complications are rare. 2
- There is no evidence that mumps causes congenital malformations, unlike rubella. 3, 2
- A 1966 study suggested increased abortion risk with first-trimester mumps, but subsequent studies have not consistently confirmed this association. 2
Special Management: Facial Nerve Involvement
If facial nerve inflammation occurs:
- Initiate corticosteroid therapy promptly with prednisone 1-2 mg/kg/day for 5-7 days followed by a taper over 5-7 days to reduce inflammation and improve nerve function. 1
- Provide eye protection to prevent corneal damage in patients with facial weakness. 1
- Reassure patients that complete recovery occurs in approximately 70-80% of cases within 3-6 months. 1
Critical Clinical Caveats
- Mumps disease is generally self-limiting, with most patients recovering without intervention beyond supportive care. 1
- Parotitis is not present in all cases—only 30-40% of mumps infections produce typical acute parotitis, while 15-20% are asymptomatic and up to 50% present with nonspecific or respiratory symptoms. 1, 4
- Complications are more common and severe in adults than children, making age an important consideration in monitoring intensity. 1
- The mumps vaccine is contraindicated during pregnancy due to theoretical risk of fetal harm from live-virus vaccine, though accidental vaccination has not been shown to cause maternal/fetal complications. 3, 5
- MMR immunization should be administered to nonimmune obstetric patients upon completion or termination of pregnancy to prevent future infections. 5
