Virus replication facts

Not trying to incite anything with this scientific info. Just passing it along. Our eldest son has a PhD in biology and is a dna researcher. He told me the following (paraphrased):
Viruses cannot replicate themselves alone. They must successfully enter plant or animal cells in order to do so. He said absent that they are simply inert bits of dna or rna.
Hence the advice to distance ourselves. The more contact the more opportunity it has to replicate. Not what anyone wants to do but now it makes more sense to me. Bummer.

Unfortunately he added “It is not going away completely. The genie is out of the bottle.” More bummer.

I read somewhere that viruses mutate - generally becoming more damaging but less contagious and so they die out. Alternatively (as the OP states) they die off as they have nobody to infect. I don't think we can ever relax until we get both a cure and a vaccine. Thankfully lots of very clever people are caring for the sick and working on a cure or vaccine. We WILL get through this together.

I meant the contagion dies out (before someone points out that a virus is not alive so cannot die)

I suspect you’re on the right track. But I am no expert, just reporting what our son said to me. I think his point was about the bug’s ability to expand. It needs new victims to expand its territory. Hence he thinks slowing its ability to find no new hosts that ability is limited. So a pain for us is a decent defense. I do know he is being very judicious with he and his family’s human contacts.
Again I’m no expert and just trying to impart something I’ve learned.

I thought they became more contagious but less damaging. That fits with natural selection. Less virulent strains survive better because they do not kill the host who then lives to pass it on to as many people as possible.

I want to know, who invented this virus? It just didn't happen out of thin air!

Perhaps. Our son did not go into that aspect/question. Only what I tried to share in the original post about how they “grow” although the word he used was “replicate.”

Shi Zhengli, a Chinese research virologist, was working with the original virus. She even stated that they had created a synthetic virus from the original by genetically manipulating the external proteins, which would allow for human contamination. This was done in the P4 section of the Virology Center in Wuhan.
BTW: No bats at the wet market where the CCP stated the SARS-CoV-2 started.

Viruses are strange, not living, but they are actually fairly easy to deactivate. They have a "fatty" coating which maintains their potency to invade cells, but that coating dissolves when heated, hence their low survival rate in summer. Since soap dissolves fat as well, that's why warm/hot soapy hand-washing is a great self-protective measure.

I would add that there is some controversy about RNA viruses and whether they are "alive". Some scientists think that, for a variety of reasons these RNA (and DNA) viruses are "alive" and others that they cannot be classified as 'living' things. All I know is that their exposure, depending on the type of virus that is present, can result in significant morbidity and in some cases, mortality. Be safe friends.

Shi Zhengli (simplified Chinese : 石正丽 ; traditional Chinese : 石正麗 ; born 26 May 1964) is a Chinese virologist who came to international prominence as "bat woman" during the 2019–20 coronavirus pandemic for her work bat viruses. Shi and colleague Cui Jie found the SARS virus originated in bats.
