As Delhi recorded 107 fresh Covid-19 cases which is the highest in six months, a health expert said this spike could be due to the Omicron variant.
Speaking to ANI, AIIMS Community Medicine Department Head Dr Sanjay Rai said, "The infectivity of Omicron variant is very high. When it goes to a susceptible population, then it will rise and fall quickly just like it happened in the second wave. It is a natural phenomenon and we need to watch it closely."
