Immunity to COVID had to have existed prior to 2019, given that the wet markets in China including bats isn't a new practice. Humans had to have been exposed to the same conditions where the outbreak started for many years prior to last year; it would stand to reason that at least some people exposed to those conditions came into contact with the virus and developed immunity.
Obviously, viruses mutate and different strains occur, some more deadly than others; but it wouldn't surprise me that immunity to this virus existed beforehand.

Effect of a wet market on coronavirus disease (COVID-19) transmission dynamics in China, 2019–2020
A novel coronavirus (SARS-CoV-2) originating from Wuhan spread rapidly around the world to give rise to the most important pandemic event in recent history.
Duchess' abysmal ignorance aside, wherever COVID originated from, humans had to have been exposed to those conditions prior to the pandemic, since the conditions that created the outbreak were most likely not new and came from common practices like wet markets or farms.
I started a thread a few weeks ago showing that industrial farms may be the source of the next pandemic. While something must be done about that, industrial farms aren't new and it's likely that there are humans who have already been exposed to and developed immunity to any infections from such environments.

"Many experts think Covid-19 likely originated in the Huanan Seafood Wholesale Market in Wuhan, which has been linked to early confirmed cases."
Honestly, there's no excuse for Duchess' level of ignorance in this day and age.

Now where else did I read something like this recently, in here, oh yes, me!
But hey, the Guardian has proclaimed it so it must be true!

@vivify saidImmunity is not a binary concept. There is plenty of cross-immunity.
Immunity to COVID had to have existed prior to 2019, given that the wet markets in China including bats isn't a new practice. Humans had to have been exposed to the same conditions where the outbreak started for many years prior to last year; it would stand to reason that at least some people exposed to those conditions came into contact with the virus and developed immunity. ...[text shortened]... more deadly than others; but it wouldn't surprise me that immunity to this virus existed beforehand.
Even if SARS-CoV-2 is truly a novel virus for humans, it's quite possible that antibodies (or T-cells, which produce those antibodies) made in response to other coronaviruses or other pathogens in general could help fight off SARS-CoV-2. For example, there's a lot of evidence that people immune to SARS-CoV-1 (the original SARS) have some immunity to SARS-CoV-2. There's also some evidence that vaccines used against other viruses (such as the flu or MMR shots) stimulate the immune system to produce antibodies that could be useful against COVID.
That some people can fight off COVID without getting sick has been known for many months and T-cells produced in response to other pathogens is the most likely reason.

@athousandyoung saidFor once I agree with you

The post that was quoted here has been removedThe virus orientated in Wuhan, China. I think we know this because the first recorded cases were in Wuhan, China. We know this because Chinese scientists operating in Wuhan, Chain told the world. I think it’s fair to say that the virus originated in Wuhan, China? No, absolutely not! Racist!
By a strange quirk of coincidence there is viral research institute in Wuhan, China. By an further and even more quirkier coincidence the virtual research institute in Wuhan, China has been an active research center for the study of coronaviruses. I’m sure the virus originated elsewhere though because it’s just too far fetched to believe mistake happen in these places.
In Wuhan, China there are several wet meat markets which are a hotbed for viral propagation but it is also too far fetched to believe that the virus originated in one of these.
No, the virus point of origin is unknown and will probably always be unknown.
