Lightning Learning: Mumps
STOP!
In England and Wales (2018) there were a total of 836 confirmed cases of Mumps. In the 1st quarter of 2019 there have already been 756 confirmed cases.1
Children in the UK have 1st and 2nd MMR vaccines at 12 months and 3 years 4 months.2
1st MMR vaccination is 78% effective (range 49% to 91%) at preventing mumps. Completing two vaccinations of MMR increases this to 88% (range 31% to 95%).3
SYMPTOMS
Parotitis (occurs in 95% of symptomatic cases). Peak size of parotid glands occurs at 2-3 days. A quarter of cases can have unilateral parotitis. Non-specific symptoms include: fever, headache, earache and general malaise.4
