As many as 90 per cent patients in Mumbai, who tested positive for COVID-19 in January and February this year, were residents of high-rise buildings, while the remaining 10 per cent were from slums and chawls, the city civic body has said. However, the situation has changed to some extent this month as the number of cases from slums are also going up, civic officials said.

Of the total number of 23,002 people, who tested positive for COVID-19 in the first two months of this year, 90 per cent were residents of building and 10 per cent others from slums and chawls, the Brihanmumbai Municipal Corporation (BMC) said in a release.
