About this release

This release provides data for COVID-19 hospital onset cases in Scotland from week ending 1 March 2020 to week ending 12 September 2021. 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. Infections have been widely reported in the community. Further information on the epidemiology of COVID-19 in healthcare settings can be found on the Public Health Scotland website.
