B26.9

Clinical Causes: Infection with the mumps virus, a member of the Paramyxoviridae family Person-to-person contact through respiratory droplets from coughing or sneezing Sharing drinks, utensils, or objects contaminated with the virus Close contact with an infected individual, especially in crowded settings like schools or dormitories

Key Symptoms: Swelling and tenderness in the parotid glands (located near the ears and jaw) Pain while chewing or swallowing Fever, typically mild to moderate Headache and muscle aches Fatigue and general feeling of being unwell Loss of appetite Possible earache or pain behind the ears

Diagnosis Path: Diagnosis of mumps without complications involves a review of symptoms and patient history. Healthcare providers may perform a physical examination focusing on swelling of the salivary glands. Laboratory testing, such as detecting mumps virus RNA via reverse transcription-polymerase chain reaction (RT-PCR) or identifying mumps-specific antibodies, can confirm the infection. Imaging studies are generally unnecessary unless complications are suspected, which are not part of this ICD classification. Differential diagnosis includes other causes of salivary gland swelling, such as bacterial infections or tumors.

Treatment Protocols: Management of mumps without complications primarily involves supportive care to relieve symptoms. This includes rest, adequate hydration, and over-the-counter medications like acetaminophen or ibuprofen to reduce fever and discomfort. Applying cold packs to swollen areas may help with pain. Since mumps is caused by a virus, antibiotics are ineffective unless there is a secondary bacterial infection. Most individuals recover fully within a couple of weeks, and no specific antiviral treatment is typically required. Isolation during the infectious period helps prevent transmission to others. Vaccination is the most effective way to prevent mumps infection.
