Sources of transmission

I have heard that one is unlikely to catch Covid from surfaces as opposed to breathing it in from the air .

Can anyone tell/reassure me that this is indeed the case and perhaps quantify the relative likelihood of catching this virus from these 2 different sources of infection?

Is it half as likely ?A hundred times less likely? In between?

Also is the new B117 variant a new variable in this regard?

Is it more transmissible from surfaces than the old virus from last year?

"As evidence has accumulated over the course of the pandemic, scientific understanding about the virus has changed. Studies and investigations of outbreaks all point to the majority of transmissions occurring as a result of infected people spewing out large droplets and small particles called aerosols when they cough, talk or breathe. These can be directly inhaled by people close by. Surface transmission, although possible, is not thought to be a significant risk."

Thanks.With the caveat of avoiding any surfaces that have been in close contact with the mouth or nose or just greatly used by the public (doornobs etc) it seems to me that the risk of infection from surfaces in general may be almost insignificant.

It seems there have been practically zero verified cases of transmission in that way since this pandemic started.

Maybe I can now dispense with my routine wiping of the groceries that I have performed religiously over the past year ?

(I always knew it was overkill but figured it did no harm)

I really wish it was surface spread, as that's easily controlled by cleaning surfaces, washing and sanitising hands and not touching your face.

Viruses that tend to spread more through touching surfaces are less susceptible to cleaning. Soap / sanitising breaks down the lipid coating on enveloped varieties such as coronavirus/ influenza. Non enveloped viruses such as norovirus, adenovirus etc are less susceptible to cleaning- hence why they present more of a surface threat

The paranoia and hysteria by governments the media and the public has been absurd in the absolute extreme and endangers civilisation and the human race as we know it.

Did you really just claim that the panic and hysteria is from governments and follow up with predictions of the end of the human race as we know it? Has to be a piss take

Surface spread has to be low if you look at infections in supermarkets, otherwise those stacking shelves would be infected in the hundreds every week.
