Variants are new versions of the virus responsible for the Covid-19 epidemic.

3 main variants have been discovered: one in the UK, one in South Africa in 2020… and one in Brazil, (sometimes called Japanese), in January 2021.

But where do these new virus versions come from?

Viruses mutate to survive! It’s true for viruses and for all living organisms.

These mutations help species evolve and are what causes diversity.
