Meeting of the Parliament (Hybrid) 16 March 2021
There is a direct correlation between community transmission of the virus and nosocomial infection and transmission. As community transmission rates have fallen, so have infection rates in hospitals. Initially, therefore, the most important thing is to get community transmission rates down. A range of work is undertaken in hospitals—not just in relation to Covid, but generally—to reduce the risk of infection.
The University of Edinburgh study is an important paper that highlights a number of issues that the nosocomial review group has considered. It shows a strong epidemiological association between hospital exposure and severe Covid, but it does not confirm causality between the two. That does not make the information unimportant, but it is important to understand the difference.
The paper makes it clear that the reasons for the association are likely to be complex. The report does not say this—it is me saying it—but, for example, people who are in hospital are likely to have health conditions already, so, if they get Covid, they might be more vulnerable to becoming more ill with it. We will consider the paper carefully and feed any learning from it into the wider work to reduce, as far as possible, the risks of hospital-acquired infection.
