It's been said for a long time that the chances of transmission from surface contact and extremely small. I've copied an extract from a BBC article today below providing further details.
With this in mind, shouldn't we rein back on the "hygiene theatre" that has become part of daily life in so many places. In particular schools where, despite being in close proximity and massless all day, pupils and teachers spend an entirely disproportionate amount of time washing and sanitising. This isn't merely harmless activity, but actively reduces the amount of education our children are receiving as significant time is wasted carrying out these elaborate rituals.... all to give the false impression of being "Covid-safe".
Enough... Of course hygiene is good, but there's no excuse now to get back to normality in this area.
"At the start of the pandemic, a lot of focus was on surfaces. People washed groceries and avoided touching buttons at pedestrian crossings. Councils shut playgrounds and cordoned off park benches.Yet it's been all but impossible to find an outbreak linked to an infected surface. "It's to do with how the virus actually enters your system - it's* through the airways," says Dr Eilir Hughes, a GP and campaigner for more protective PPE for NHS staff.The virus takes hold in the body via the respiratory system - that's why testing for it involves a swab up the nose and down the back of the throat. It would take an extremely unlikely chain of events for infected droplets on an object to end up in someone's nose or throat. Hygiene is important, but washing hands and surfaces excessively, and avoiding touching objects - so-called "hygiene theatre" - has little impact on the spread of Covid."*
