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.<br />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."<br />
