How much is really known about how the SARS-CoV-2 virus is contracted by individuals ?
We have been told that an infected person can distribute the virus in droplets emitted from their nose or mouth.
We have also been told that these droplets can subsequently be received through the eyes, nose or mouth of individuals who come in to contact with droplets present in the atmosphere.
We have also been told that the virus can remain viable on surfaces for up to 72 hours, thus anyone touching these surfaces can subsequently infect themselves by touching their own eyes, nose or mouth.
We have also been told that you can not become infected through your skin.
I have no issues with any of this widely available information.
However, what I would like to know, is how the reported 3.7 million people who have become infected by the virus became infected.
How many became infected through inhaling droplets containing the virus ?
How many became infected as a result of touching a surface that was contaminated by the virus, then touching their own eyes, nose or mouth ?
What is the current thinking on the percentage split of how people become infected ?
A very genuine question, and one that requires to be suitably addressed and understood to guide the progress of a relaxation of lockdown measures.

I doubt the figures you ask about can be calculated.
You could breath it in, sneeze into your hand and transfer it all over Maybe not sneezing or coughing it out causes it to build up Smokers cough seems to reduce bad symptoms But so many variables to consider. Probably more chance of backing first three home through the card on ebor day at York. |

Remember to :
Disinfect : phone, keys, glasses, wallet when you come home. Also take off shoes at door....or if not.....assume virus is on the floor. |

Very simple but good question/s.
It would be an excellent one to throw into a daily briefing to be answered by an MO,even a guesstimate would do but would undoubtly be fudged. |

My guess, based on little or nothing, is that washing hands has roughly the same effect on respiratory virus cases that passive smoking has on lung cancer - the vast majority of people are going to get it in the obvious way

Clearly there will be scientists and medical staff researching this topic, understanding how people become infected is a key element in battling the virus.
But I haven't personally heard it being discussed anywhere in the public domain. It's also interesting as we have heard from some of the anti-lockdown lobby that infection rates were significantly falling ahead of the lockdown as a result of the high profile hand washing campaign. Meanwhile, there have been 23,737 new cases reported in the UK in the last five days, that's an average of 4,747. We are also lead to believe that a significant number of these new cases are coming from hospitals and care home settings. Now, you'd expect that in hospitals, they will have very high standards of hygiene, pointing more to inhalation rather than touching being the source of infection. My gut feeling is that inhalation would be the higher contributor, but I just don't know. |

My bet would be that a good percentage of those infected would have picked it up from bank notes and transferred it to their face. I wash my hands every time I touch a bank note, even at home.

I guess one touches one's face regularly, and hands touch surfaces. As viruses are usually transferred from one human to another thro contact with surfaces I believe washing one's hands esp in Covid-19 is an effective way of minimising an infection. But it will not stop one from inhaling the droplets containing the virus esp if the Covid-19 droplets are transferred to one's face with our hands and in close proximity of our eyes and nostril, the passages into our central nervous system.
The only certain way is self-isolate (if one is Covid-19 free) and not share one's space with anybody else, selfish as it may seem. |
