WHO tracking 4 omicron sub-variants, says preventing all COVID transmissions 'not the goal'

World Health Organization (WHO) official Dr. Maria Van Kerkhove said earlier this week that the agency is tracking four omicron sub-variants, including BA.1, BA.1.1, BA.2 and BA.3.
"Now, we already know that omicron has a growth advantage; it's more transmissible compared to other variants of concern and also has properties of immune escape," she said. "But, we know some of the sub-lineages, BA.2, has a growth advantage even over BA.1."
Van Kerkhove said that means that as the virus continues to circulate, there will be an increase in BA.2 cases.
