About this release

This release provides data for COVID-19 hospital onset cases in Scotland from week ending 1 March 2020 to week ending 25 September 2022. A system for monitoring COVID-19 is critical to tracking hospital transmission. This helps to inform infection prevention and control measures. The transmission of COVID-19 is thought to occur mainly through respiratory droplets generated by coughing and through contact with contaminated surfaces. Further information on the epidemiology of COVID-19 in healthcare settings can be found on the Public Health Scotland website.

Due to the cessation of almost all population for SARS-CoV-2 at the end of April 2022, the inclusion of community onset cases in this report has been discontinued.
