(I will ask though.. Re 'touching surfaces' such as in an aircraft from Iran, an attendant handling plastic cups or water bottles passed from the window seat to the aisle or vice versa. What are the chances of Corvid-19 infection vs a muffled sneeze in this scenario? That's certainly not an example of 'social distancing'. That's five fingers carefully gripping the container, seizing it many times at the window seat, then relaying it to the steward or stewardess (aircraft attendant)
And what if the attendant is infected ? And was infected a week earlier via handling a carry on case too heavy for an elderly infected passenger who arrived by wheelchair in Atlanta, bound for Melbourne, Australia ? His or her carry on was also handled by airport security who pushed the wheelchair through Security to the gate ?
We need to know ALL the modes or routes of likely transmission.. we need to know the predominant modes if at all possible. We need to know, if realistically.. social distancing is more an 'empirical' triage strategy.. ie keep people close to home, away from infection.. fair enough.. quite effective & highly useful. But what are the key infection places or typical events ? Society at large will be enthusiastic & grateful and buy into avoiding or protecting against those scenarios.
I recall reading or hearing, early on.. that Corvid-19 was incapable of skin to skin transmission. I do wish I could find that 'knowledge' and who reported it publicly. In hindsight it now seems ridiculous.
There is little doubt, Sal, that there is much to learn from this whole experience - but only if we prove to be apt students, something our rather tortured history as a species renders a mixed verdict on.
.. FYI .. It does seem 'person to person' transmission is the most likely route for infection (CDC & WHO).. but - Covid-19 does not enter via skin to skin contact. It needs to move via a handshake for example, then make its way upward to the eyes, mouth nose (mucous membrane) hence 'don't shake hands, wash your hands, do not touch your face'. Yes, it can be picked up from surfaces onto hands.. then up to the face - and infect - a cough or sneeze, or even singing or breathing may land tiny moisture droplets on many different surfaces where the virus can survive approx 48 hours, hence the 'social distancing' enforcement
There are all kinds of lessons to be learned at this time, Lorne -- if we're paying attention.
ReplyDeleteSo very true, Owen.
Deletepretty good
