Abstract

Highlight

- Mumps is a vaccine-preventable disease caused by the Paramyxovirus, transmitted through direct contact or respiratory droplets from infected individuals.

- In 2025 (as of 15 October 2025), a total of 1,646 cases of mumps were reported, with a morbidity rate of 2.49 per 100,000 population, and no deaths were reported.

- Although cases had declined over the past decade, the 2025 incidence increased, exceeding both the five-year median (2020–2024) and 2024 levels.

- Outbreaks occurred mainly in schools and healthcare facilities, often associated with close contact or shared activities.

- Prevention and control of the disease can be achieved through appropriate immunization with the measles-mumps-rubella (MMR) vaccine and by maintaining good personal hygiene. Individuals with mumps should stay home from school or work for at least 5 days after the onset of swelling to prevent transmission within the community.
