Omicron Part 2? Yes, there is a new variant: Omicron BA.2

As COVID ravages the world, it has done so in various mutations. First, there was the generally known COVID-19 strain. Then came the Delta variant. We are living with Omicron right now and most of the infections are from the Omicron BA.1 variant.  

Omicron was first discovered in November 2021 and exists as three variants: BA.1, BA.2, and BA.3.  BA.1 was strong and spread quickly. Few thought that the weaker BA.2 and BA.3 variants would amount to anything. That has changed and BA.2 is starting to spread in South Africa and parts of Europe. 

For epidemiologists, it is still early days in their understanding of BA.2. Some believe is it slightly more contagious that BA.1 and others believe it could lengthen the Omicron surges in both Europe and the United States.
