How many variants of COVID-19 are there?

COVID-19 has evolved quite a bit since the start of the pandemic, creating more and more strains that show strength to evade the vaccine.

The newest variant appears to have derived from the delta variant and looks to be more contagious than the original.

The new strain is known as AY.4.2 and called Delta Plus by some. It’s especially spreading in the U.K.




There are in total 56 known variants that stem off the original Delta Variant, and this newest one is technically a subtype of a subtype of the Delta Variant.

AY.4.2 came from AY4, which came from Delta, which stems off the first COVID virus.

Dr. Scott Gottlieb believes researchers need to quickly understand the newest strain before it replaces Delta.
