Typically, most variants in diseases originate via Zoonosis (animal to humans) and this gives the disease a very fast route of spread in the human population. That's how Covid started but then Covid did something unusual...variants begin to be birth in the not vaccinated population (often in immunocompromised individuals) until Omicron that many scientists are still debating if Omicron originated via Zoonosis...as in Reverse Zoonosis. Kristian Andersen, an immunologist at the Scripps Research Institute, is among those who have been raising the idea that Omicron may have emerged from a reverse zoonotic event. (A zoonotic event is when an animal pathogen starts to infect and spread among people. A reverse zoonosis is when such a virus passes back into animals / then mutates in an animal species to then infect humans again.) If Omicron did originate from rodents in South Africa while other variants were birth from human to human... This spells a lot of trouble in the future in that Covid will easily surge again...whenever it wants to when society in some country quickly forgets what happened in 2020 and 2021. As stated, statistically...most variants of Covid are via Zoonosis and then follow by being birth in Not Vaccinated Immunocompromised individuals and then follow by Vaccinated Immunocompromised individuals. Will one of these countries birth the next Variant of Concern via Zoonosis @ https://www.oie.int/en/what-we-offer/emergency-and-resilience/covid-19/#ui-id-3 ??? One of the peculiar traits of SARS-2 underpins this thinking or reverse zoonosis. It is what virologists describe as a promiscuous virus; it is capable of infecting a number of species. Dogs and house cats. Large cats. Mink. White-tailed deer. Given how easily the virus seems to jump from species to species, people studying it assume this list will grow. P.S. I've decided to buy a custom RV so that I'll be able to travel when the next Pandemic hits. There are just too many Covidiots in this world trying to fuck up everything for everybody else. I wonder if they make electric vehicle RVs ??? wrbtrader
You lack basic math skills. I guess you opted out in high school and took typing instead. Gives you more ability to type a lot about math you don't understand.
