In the first two months of the lockdown, cases in Mumbai had reached 25,000, while in the rest of MMR it was 7,356.
But as the region started to open up as part of Unlock 1, the number of COVID-19 cases started increasing in the MMR.
On May 23, Mumbai had an 80 per cent share of the total number of cases and 89 per cent of the total deaths in the MMR region.
However, it still accounts for 80 per cent of the total number of deaths in the region.
