Good news is that trees and plants don't need toilet paper. Seriously, I don't think trees and plants can get a human virus. They can become carriers if the virus lands on them, but they can't get sick from the human virus. There is no evidence that I am aware of that viruses can jump from one species to another. In fact, a virus is ''organ-specific'', meaning that once a host has a virus, not every organ is equally affected by it. A lung virus doesn't jump to the heart, or vice versa.
Trees and plants spread pollen, if they got infected the pollen will infect the rest of the world real quick. Insects might got infected too and result will be devastating.
Didn't spend much time awake in biology class, didja?
Viruses attack certain types of cells. COVID attacks respiratory cells - lungs. Plants...don't have lungs. Therefore...they won't contract COVID.
If a host does not have the type of cell (receptor) that the virus specifically can invade, the host is not in danger.
Insects may have lungs, but unless they have the same cellular makeup as humans (which they don't, or they'd be...human) they can't carry it either because the virus cannot attach itself to the host.
Oh, that's not an argument. It's a fantasy RPG beating on Trolls.
YES. viruses DO jump species. Almost all the flu epidemics from China ( and elsewhere, China isn't the only place on Earth, Ever, to have pre-medieval farming conditions.. ) are from pigs, chickens, and bats. ( Monkeys, AIDS, Ebola, etc. )
Bugs and rodents carry viruses even if it doesn't kill them. ( quickly ) The virus reproduces, taking over and killing cells as it multiplies, but slow enough to spread far & wide. Arguably, many viruses are BETTER at infecting rats than humans since it doesn't kill them as fast. With the Bubonic plague, it's flea/rat borne. So it's hanging out in the fleas & rats, who get sick, and instinctively travel to escape... and the fleas move on to new hosts.
It's most common that intestinal viruses in feces crosses to humans from birds, etc. When the feces dries, blows around as dust, gets in the lungs, then into the bloodstream.
It's not necessarily true that a lung virus is a lung virus... what is a tummy bug to a pig can be a breathing problem for a human. Or attack the heart. And viruses mutate quickly, having no DNA redundancy. ( with the possible exception of man made mutations, but I don't know how that's supposed to work in detail. )
Coronavirus receptors are only good for lung tissue.
Mostly but not completely so.
I'd have to look it up for Coronavirus specifically, & You may be correct for today's strain. But viruses may cheerfully attach to a variety of cells. Some to only one type, yes. Others to, say, ovary and pancreas...
And, insects don't have the exact same type of tissue in their air tubes as your lungs, but a virus might be happy with the saliva producing cells, which is one reason insect transmitted diseases are fairly common. ( ticks & Lyme disease? )
Although most insect transmitted diseases in the U.S. are mosquitoes biting an infected person and passing it to the next in a somewhat disgusting way.
s there evidence that coronavirus comes from animals? Or that it can jump between species?
Yes.
One of the reasons the flu and -19 are, or can be, so deadly is a virus well adapted to a critter host, doesn't quickly go wild and kill them, may be fast and nasty when it jumps species.
2000 infected died in USA last 24 hours. So right now more than 2000 infected people in USA are doomed and will die within next 24 hours and there is nothing we can do about it.
1). Terribly ill informed 2). Poorly educated 3). Lacking the most basic common sense and intuition 4). Trolling 5). As full of shit as a Christmas goose 6). Pulling our collective legs
I’m going with 6. . . . None of the others could explain it.
Pat, yes, today’s strain, and the ones that cause MERS, and SARS. The kind of coronaviruses that can invade nose and throat tissues are not as lethal as the lower respiratory variety.
I just don't buy your whole shtick. You may have your ducks in a row, but something's off about you. Something smells, and my crap detector pings real hard with you.
In your profile, you said your top speed on two wheels is 70mph. So, your telling me you built that bike, are a motorcycle enthusiast, and you've never been over 70mph?! That simply does not compute with me.
