Mumbai: Maharashtra Chief Minister Uddhav Thackeray today pointed out that the number of daily coronavirus cases in Mumbai – one of the country’s worst-hit cities – has doubled over the last few days. Calling the Covid situation in the state “serious”, Mr Thackeray, in a virtual address, said it would take a couple of weeks to ascertain if the current upsurge in daily figures is a fresh wave of infections or not. He also warned people to follow coronavirus protocols to avoid another lockdown.”Do we need a lockdown? If you behave responsibly, we will know in the next eight days. Those who don’t want a lockdown, will wear a mask. Those who want a lockdown, will not wear one. So wear a mask and say ‘No’ to the lockdown,” he said.”Whether this is a second wave or not, we will understand this in the coming 8 to 15 days,” he added.
