About this release

PHS provides quarterly information on the following immunisations and vaccine-preventable diseases under surveillance in Scotland:

  • Haemophilus influenzae
  • measles
  • meningococcal disease
  • mumps
  • pertussis
  • invasive pneumococcal disease
  • rotavirus
  • rubella
  • shingles​

Main points

  • The number of reported cases of vaccine-preventable diseases in Scotland generally remains low and stable.
  • The number of reported cases of invasive bacterial diseases (Haemophilus influenzae, meningococcal disease, invasive pneumococcal disease) to the end of the third quarter of 2020 is lower than for the equivalent period of the previous four years.
  • No cases of measles were reported during the first three quarters of 2020, however increased measles activity in Europe and globally continues to pose a threat to international travellers and Scotland as global travel restrictions are relaxed during the COVID-19 pandemic.
  • The number of mumps cases for the first quarter of 2020 was 853, which exceeded the 784 cases reported in 2019, and continues to be highest in individuals aged 17 to 34 years. Although the vaccination status of cases is not routinely collected, this is consistent with the age groups which are likely to be under-immunised with a mumps-containing vaccine, or for whom there is waning immunity.
  • A notable reduction in mumps cases has been observed since March, in comparison to the first two months of 2020 where 853 cases were reported. The trend has continued, with only 10 cases reported between April and June and no new cases in quarter three of this year. The declining trend may be expected to continue as a result of social distancing measures to mitigate the transmission of COVID-19, which may interrupt the transmission of mumps. It may also reflect reduction in diagnoses due to reduced attendance at primary care services.
  • A notable reduction in mumps cases has been observed since March to the end of the year, with majority of cases occurring in the first two months of 2020. The trend has continued, with only 11 cases reported between April and December 2020. The declining trend may be expected to continue as a result of social distancing measures to mitigate the transmission of COVID-19, which may interrupt the transmission of mumps. It may also reflect reduction in diagnoses due to reduced attendance at primary care services.
