human immunodeficiency virus mutates quite rapidly
. Consequently, many of its genetic variants have been categorized. Indeed, geneticists have divided the predominant HIV virus into at least nine subtypes, or clades. Interestingly, these variants differ in their geographic distribution. Most infections in North America, western Europe, and Australia are caused by clade B. In contrast, clade C is much more prevalent in southern Africa and clade A is more prevalent in Russia and former Soviet Union countries.
So, what has driven the geographic distribution of these variants? Probably, the predominance of different clades in different geographic regions largely is due to chance. If a certain variant enters a particular population, then that variant could spread throughout the population, quickly becoming the dominant variant. This process probably explains the. Most likely, one of the first people in the United States infected with HIV happened to be infected with a clade B version of the virus.
In this case, random mutations led to the evolution of a new virus. The genetic code of FPV, replicating in a cat changed and, as a result, the exterior of the virus changed, which meant that unlike its predecessors, this variant of FPV could infect the dog. The virus replicated in this new host and spread to other dogs. Thus, a new virus emerged and quickly spread throughout the world.
Long winded article that talks more about HIV than Covid. TLDR: the new strain spreads faster and they dont know if the vaccines will be less effective against it. The end.
Variants are never stronger Did the virologisake this clear on the article?
Usually viruses dilute, they weaken as they transform to a new variant.
The Teenage Mutant Covid 🐢Turtles are mutating. Hide your head in your shell.

thank you very much for your work
