Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment his Department has made of the effectiveness of air sanitisation and UV-C sterilisation units on reducing the spread of covid-19 in confined public spaces.

Public Health England (PHE) has made no assessment of the effectiveness of air sanitisation and ultraviolet C (UV-C) sterilisation units on reducing the spread of COVID-19 in confined public spaces.

PHE is liaising with national and international partners on the effectiveness of UV-C for inactivating SARS-CoV-2, the virus responsible for COVID-19.

PHE will continue to review the emerging evidence.
