The number of active patients is now below 20,000 in the city, and the number of symptomatic and critical patients has gone below 8,000 for the first time since the last week of August. The number was over 8k for the past two months. In August, when the city saw few new patients of COVID-19 and the pandemic seemed to decline, the total number of symptomatic and critical patients was over 8,000 for past 2 months.

But after the Ganesh festival, the number of patients started increasing rapidly and the active patients' number had touched an all-time high of 34,136 on September 18. At the same time the symptomatic patients increased to 8,376 along with 1,233 critical patients. The Brihanmumbai Municipal Corporation (BMC) then decided to increase the capacity of institutional quarantine, CCC2s as well as ICUs and ventilators.
