Sir, there is great concern about the difficulty in treating a reasonable number of patients per session while we need enhanced decontamination between patients. During a conversation with my grandson he suggested that perhaps family groups and those living in the same social bubble might be treated in a single session. As they would be living in the same bubble, perhaps it would only be necessary to use the normal decontamination methods, as were used pre-COVID? This would help to deal with the considerable backlog, by reducing the time between members of the same household.
