Mumbai's sealed buildings count crossed 10,000, with over 3,500 buildings added within 20 days. The Dahisar-Malad belt has 35 per cent of the sealed buildings and 25 per cent of the city's active COVID-19 cases.

The civic body has often changed rules for sealing buildings. While initially even neighbouring buildings used to be sealed if a case were found in one building, later only one wing got sealed.
