To slow down the transmission of COVID-19, the Brihanmumbai Municipal Corporation (BMC) has started a massive sanitation campaign and so far has sanitised over 4,100 areas by spraying 830 litres of sodium hypochlorite in last 15 days.

While the priority is being given to areas where quarantine patients are placed and positive virus cases were found, housing societies and slum areas too have approached their local elected representatives to get the civic officials to disinfect the area.
