About this release
This weekly release by Public Health Scotland presents epidemiological information on respiratory infection activity, including COVID-19, across Scotland.
Overall assessment 06 November 2023 to 12 November 2023 (ISO week 45):
- Measures of respiratory symptoms in the community and via attendances at GP consultations show Baseline activity levels of respiratory disease activity during the reporting period (NHS24 and GP ILI).
- In the CARI community surveillance system, which tests for ten different pathogens, rhinovirus swab positivity was stable at 24.8%. This was followed by RSV with a swab positivity of 11.8%, which was a decrease from 14.7% the previous week. Swab positivity for pneumoniae and COVID-19 was stable at 8.3% and 5.9% respectively in week 45.
- Virology data show influenza circulated at Baseline activity level. RSV remained at High activity level. For RSV, the 1-4 and the under 1 age groups were at Extraordinary activity level. Mycoplasma pneumoniae and rhinovirus were at Low activity level.
- The overall number of emergency hospital admissions because of RSV and COVID-19 decreased since the last week, while admissions observed for influenza remained stable. The largest proportion of admissions were for RSV. ICU/HDU admissions remained low.
- All-cause excess mortality for week 42 (week ending 22 October 2023, the latest week not impacted by reporting delays) remained at Baseline activity level overall and for all age groups.
- Since 4 September 2023 (the current Winter 2023 vaccination programme) 1,235,699 influenza (Adult 18+), 333,375 influenza (Children 6 months to 17 years) and 1,013,048 COVID-19 vaccines were administered in Scotland.
Tracking infectious respiratory diseases, including COVID-19 and influenza, is essential, especially in the winter when the disease burden can be highest. In Scotland, respiratory infection and associated morbidity are monitored using enhanced surveillance. This approach combines data from microbiological sampling and laboratory test results from community and hospital settings with data from syndromic surveillance of NHS 24 calls, primary care consultations for respiratory symptoms, hospital (including intensive care) admissions and other settings.
The intelligence generated from surveillance of laboratory, syndromic and settings provide a comprehensive picture of current respiratory illness in Scotland. The data presented in this report provide a comprehensive and timely epidemiological picture that is essential for understanding transmission of infection and supporting patient care and NHS service planning and policy.
Seasonality patterns / seasonal variations
Respiratory illnesses are associated with seasonal increase in the autumn and winter. Seasonality patterns for both influenza viruses and non-influenza respiratory pathogens have been established through many years of surveillance data. Most influenza and non-influenza pathogens circulate in the autumn and winter in Scotland, although some are known to circulate in the spring and summer. Notably, COVID-19 transmission has been occurring in waves throughout the year as observed from surveillance data since the start of the pandemic in 2020.
The next release will be 23 November 2023.
