A strict lockdown should be imposed in areas where the Covid-19 case positivity rate is over 10 per cent or the bed occupancy is above 60 per cent, AIIMS Director Dr Randeep Guleria said on Tuesday, while stressing that clamping such restrictions all over the country cannot be a solution, keeping in mind people's livelihood.

He rejected the strategy of imposing night curfews and weekend lockdowns by some states to reduce the number of coronavirus cases, saying "these would not have much of an impact on the transmission cycle".
