In accordance with my limited knowledge of virology, Covid-19 viruses, an extremely tiny existence in the world, always exert its role collectively as a whole, as is true with other germs. It has its own complete evolution process of originating, developing, climaxing, declining and terminating. Like any life, it takes its own course. Omicron variant comes, as does Convid-19 climaxing stage. It's reported that it's more infectious but less pathogenic and less fatality rate, which corforms to the feature of virus climaxing. The pandemic may be evoving into an endemic as fluenza. If winter comes, can spring be far behind？Let’s wait and see.
