Question to the Department of Health and Social Care:

To ask Her Majesty's Government what steps they are taking to ensure that NHS estates can reduce the viral load of COVID-19 in the ambient air; and what plans they have to undertake wide-scale deployment of professional high-efficiency particulate air purifiers to reduce the risk of nosocomial infection.

The current National Health Service infection prevention control principles are applicable to all healthcare staff in all healthcare settings.

These set out safe systems of working including administrative, environmental and engineering controls and interventions to reduce the risk of transmission of infection. This includes cleaning and decontamination of the environment and shared equipment, social/physical distancing, hand hygiene, personal protective equipment and ventilation.
