5 years into the pandemic, the COVID-19 virus keeps changing
Briefly

The article discusses the unprecedented and rapid evolution of the SARS-CoV-2 virus responsible for the COVID-19 pandemic. Contrary to initial expectations that it would evolve slowly like other coronaviruses, SARS-CoV-2 has shown a remarkable ability to undergo rapid mutations and jumps, evolving faster than the influenza virus. With the emergence of variants, especially the omicron subvariant, the virus has significantly adapted to evade the human immune system. Despite hints of a slowdown, the virus continues to evolve and spread, resulting in millions of infections and deaths worldwide.
SARS-CoV-2 is evolving more rapidly than expected, with notable variations allowing it to evade immune responses, showcasing an evolution rate even faster than the flu.
Scientists have observed that despite some indication of a slowdown, the virus continues to evolve, creating numerous variants, predominantly descending from the omicron strain.
