A day before India begins administering the third dose of vaccines to the most vulnerable population of the country, a total of over 1.59 lakh infections were reported, which is the highest in 224 days. The tally and the steady surge of cases in Delhi, Maharashtra, Karnataka, West Bengal indicate that what India is experiencing is a fresh surge that many states have declared as the third wave. How will this wave move? Studying global trends, experts said the surge is likely to be short-lived. The curve is likely to be small with a quick up and down, believe experts who have been warning people against the floating notion that Omicron will act as a natural vaccine. “Let’s all just get Omicron isn’t exactly the best idea. Best to avoid altogether. The surge should be quick, straight up and down. See it through with utmost precautions," Dr Arvinder Singh Soin said on Sunday.

Here are the top 10 updates on India's Covid-19 situation:
