COVID-19 cases in particular areas of some states, he said: "If we look at Maharashtra it's not the whole Maharashtra that is reporting surge in COVID-19 cases, we have to see epidemiologically where the transmission is reporting maximum, So Mumbai circles, Pune, Palghar, and Thane are the places which are reporting continuous rise in cases.
Similarly in Kerala also, although positivity is very high, there are other dimensions." "The surge in cases is dependent on three important parameters.
First is the susceptible pool of the population, you can see that what is the immunity status, which we are having in the community.
Gradually as immunity goes down you get an increased susceptible pool of population. Virus-like omicron has an increased tendency to break through your immunisation.
