RHC measles guidance (1144)

Please see the Health Protection Scotland Quick reference guide for the control of measles incidents and outbreaks in Scotland.

Please also refer to the NHS GG&C Control of Infection Committee Measles guidance. Measles Guidance V7 (interim) 

In 2018 measles virus transmission was re-established in the UK. Measles is the most infectious of all diseases transmitted via the respiratory route, with a reproduction (R) number of between 15 and 20.

The most effective control measure is high uptake of 2 doses of the measles, mumps, and rubella (MMR) vaccine. Vaccination with 1 dose is at least 95% effective in preventing clinical measles, and 92% effective in preventing secondary cases amongst household contacts (1). In the UK, the first dose of MMR vaccine is offered between 12 and 13 months, the second dose at 3 years and 4 months.

Reassuringly vaccine uptake rates in Scotland are high, but still fall below the WHO target of > 95% uptake of 2 doses by 5 years of age. In the quarter ending 30 September 2023, 93.3% of children had had the first dose of MMR vaccine by 24 months of age. This rose to 95.8% for children who had reached age 5 years of age. Uptake of the second dose of MMR vaccine by 5 years of age was 89.6%, rising to 91.0% by age 6 years of age (2).

Whilst the overall risk of measles to the Scottish population is low, current vaccination rates are below the herd immunity threshold, and imported cases could propagate local outbreaks within un- and under-vaccinated communities.
