Did a Mutation Help the Coronavirus Spread?

More Evidence, but Lingering Questions. Researchers claim that a predominating variant had a “fitness advantage.” But many experts are not persuaded.

What happens if COVID-19 mutates?

Thanks to science fiction, the word “mutant” has become associated in popular culture with something that is abnormal and dangerous. Yet in reality, viruses like SARS-CoV-2, the virus that causes COVID-19, are mutating all the time and often this process does not have any impact on the risk the virus poses to humans.

How do mutations in the virus that causes COVID-19 happen?

When viruses infect you, they attach to your cells, get inside them, and make copies of their RNA, which helps them spread. If there’s a copying mistake, the RNA gets changed. Scientists call those changes mutations.
