Social easing restrictions will eventually happen - but what does the research say? In today’s episode we’ll be reviewing what the literature says about direct and non-contact forms of virus transmission. I’ve just published a review paper on “Environmental Surface Contamination” and I’ll be picking out the key 🔑 points. In the media today, there’s some potential good news regarding how businesses should prepare for reopening. But what should they be considering? The Employment Minister, @senatormichaeliacash suggests that retailers create “COVID-safe workplaces”.
With this in mind, I’ll be setting out some valuable information about surface contamination and what areas and items should be carefully monitored and screened. Apart from simply cleaning more carefully, some workplaces should be considering updates to their cleaning audits and how they may need to test surfaces to confirm that cleaning has minimised and virus that could have been shed. The utility of PCR swab tests will also be discussed as a pro-active way to perform cleaning validation as a form of environmental surveillance.
I'll be leaning heavily on a paper I wrote and that was just published on the topic of environmental surface contamination that is a mini-review of the state of the literature as this documents surface transmission risk. The full paper is here.
In one study involving hospital environmental hygiene, computer keyboards used by nurses were found to be contaminated at almost 17%.
In another study, this time in Singapore, nearly 57% of rooms had at least one contaminated surface. Their research showed that the most contaminated areas/items were: toilet seats and flush buttons at nearly 19%. This emphasizes the important of the feacal method of virus transmission into the local area environment.
