Analysis of the proportion of people in Wales testing positive for COVID-19 antibodies for 13 to 19 February 2023.

The antibody data presented is part of the Coronavirus (COVID-19) Infection Survey (CIS) which is run across the whole of the UK. The data can be used to identify individuals who have had the infection in the past or have developed antibodies as a result of vaccination.

Data collection from the COVID-19 Infection Survey (CIS) has now finished and UKHSA is working with ONS and the devolved nations, including Wales, to develop a new health monitoring survey which will include monitoring of flu and other viruses as well as COVID-19. This release will, therefore, be the final edition of this report.
