Mumps is an acute viral infection that is spread from person to person. Mumps is a notifiable disease. Symptoms of mumps include fever, headache, tiredness and swollen, tender salivary glands (usually the parotid gland which is located just below the front of the ear). Mumps often gives the appearance of swollen cheeks or jaw. If you have mumps symptoms you should stay at home, not go to school or work and phone your GP and explain that you may have mumps. The best protection against mumps is to be fully vaccinated with 2 doses of the MMR (Measles-Mumps-Rubella) vaccine.
A mumps outbreak that first started in late 2018 declined in early April 2020 as a result of measures introduced in Ireland in response to COVID-19. The increase in cases later in April is a result of late notifications and is a reporting artefact. The second graph above shows the cases notified from Week 1 2019 by their Epi Date Week i.e. these cases are graphed by their onset date, or diagnosis date or laboratory specimen collected date where available and give a more accurate picture of the numbers of recent mumps cases. Note approximately 40 cases with an EpiDate prior to 2019 are excluded to aid easier data visualisation.
