The host’s own cell reads the genetic code and replicates it, making more viruses. The new virus then leaves the cell to find another host to infect. Sometimes, when the genetic code is translated into proteins, a piece of code changes. These are called mutations, and they happen quite often.

Has the virus that causes COVID-19 mutated?

Severe acute respiratory syndrome coronavirus 2, the virus that causes coronavirus disease 2019 (COVID-19), is accumulating genetic mutations that could make it more infectious, according to a study published in mBIO.

What happens if COVID-19 mutates?

Thanks to science fiction, the word « mutant » has become associated with something abnormal and dangerous in popular culture. In reality, however, viruses like SARS-CoV-2, the virus that causes COVID-19, mutate all the time, and the process usually does not have any effect on the risk the virus poses to humans.

How does the new mutation of COVID-19 differ from the original strain?

People infected with the new strain, known as 614G, had higher viral loads in their noses and throats than the original strain, although they didn’t appear to be sicker. But they are far more contagious to others.

Will a COVID-19 vaccine work for new mutations?

There is promising evidence that current vaccines will protect you from most variants or mutations of COVID-19 currently circulating in the United States. Certain variants may cause disease in some people after they have been vaccinated. However, if the vaccine is found to be less effective, it can still provide some protection. Researchers are monitoring how new COVID-19 variants affect how vaccines work in the real world. To learn more about vaccines and new variants, visit the Centers for Disease Control and Prevention.
