A guest post from Dr Evonne Curran…
The disputed airborne mode of transmission in this pandemic requires further scrutiny. Researchers have thus far focused on presenting a case for airborne transmission1 rather than disputing that the ‘primary’ mode of transmission for SARS-CoV-2 is via droplets2.
Continue readingI’ve been meaning to write an update on the Omicron variant of concern for a few weeks’ now and it’s now or never, so here we go! The Omicron variant has a host of mutations compared with previous variants, which seems to have given it the ability to spread much more rapidly. This may well be due in part to the ability to side-step antibody mediated immunity obtained through previous infection and vaccination. Omicron is spreading rapidly in the community. We don’t yet know what impact the current rapid community spread will have on hospitalisations and ultimately deaths, so time will tell.
Continue readingWe talk often about the 5 Moments for Hand Hygiene but frequently neglect the 5th moment (after contact with a patient’s environment). So much so, that you might even describe this as the “Cinderella moment for hand hygiene”! Could it be that the Cinderella moment is actually the most important in the transmission of pathogens that cause HCAI? Maybe sometimes. But that’s missing the point. If we don’t focus our attention on all moments for hand hygiene, we won’t be as effective as we could be in preventing cross-transmission.
Continue readingIt’s great to see the latest ESPAUR report published at the start of World Antibiotic Awareness Week 2021. There’s some good news in the report, but also some warning shots about our need to refocus on the risks attached to antimicrobial resistance as we move into the Covid endemic.
A guest post by Professor Sally Bloomfield explores whether we are over-emphasizing the role of hand washing in preventing the spread of infection…
If you ask whether I think hand hygiene is the single most important intervention for preventing spread of infection, I would answer yes. But I also think the COVID pandemic requires us to re-evaluate how we look at infection prevention (or hygiene) to make it relevant to the issues we now face, which are as much about “airborne “ transmission routes as hands and contact surfaces.

One of the questions I get asked a lot is “where is the evidence that wearing eye protection reduces the risk of exposure to SARS-CoV-2, because it’s really annoying to wear and creates other risks related to reduced vision”. A new systematic review examines the effect of eye protection on reducing healthcare worker exposure to SARS-CoV-2. The short answer is that there is enough evidence to convince me that eye protection should be part of our SARS-CoV-2 PPE ensemble.
Continue readingIn honour of Infection Prevention and Control Week (#IIPW) 2021, I thought I put up a quick post based on a talk I did on Friday last week about the ‘Future of Healthcare and of Infection Prevention and Control’ (you can download my slides here). I used it as an opportunity to put across my strategic priorities for the next 3-5 years. And COVID-19 is bottom of the list – keep reading to find out why…
Continue readingA remarkable new NEJM study has shown that the prophylactic administration of monoclonal antibodies reduces the risk of household contacts developing symptomatic or asymptomatic infection with SARS-CoV-2. For those who did develop symptomatic infection, monoclonal antibodies reduced to duration of disease and the duration of high viral load. This study opens up the possibility of a new tool to prevent the spread of SARS-CoV-2 to vulnerable patients in our hospitals. Is the future of managing hospital contacts of SARS-CoV-2 the prophylactic administration of monoclonal antibodies?
Probably the most contentious aspect of the COVID-19 pandemic has been PPE for staff. And within that, the most contentious aspect of PPE has been respiratory protection when caring for patients with confirmed or suspected COVID-19: to FFP or not to FFP? I have been involved in a review of international guidelines to identify variation and track the changes in the guidelines over time. Things have changed as evidence has emerged, but international guidelines still disagree on where and when FFP respirators should be worn when caring for patients with suspected or confirmed COVID-19. The review also tracked variation and changes in recommendations about what should be considered an AGP.
