The former Public Health England (PHE) established COVID-19 Hospitalisation in England Surveillance System (CHESS) across all NHS Trusts in England on 15/03/2020 to collect epidemiological data on COVID-19 infection in persons requiring hospitalisation and ICU/HDU admission. Trends in hospital and critical care admission rates need to be interpreted in the context of testing recommendations, which changed over time.

Covers admissions to 23/02/2021.
