In an attempt to curb the spread of COVID-19 in Mumbai, the Brihanmumbai Municipal Corporation (BMC) had begun focusing on senior citizens, an age group at risk for the disease, since April. They had begun checking the oxygen levels of senior citizens across the city, a task they are still handling. So far, the BMC has checked the oxygen levels of 6,74,053 senior citizens. Of these, 6,71,312 people had normal or high oxygen levels. Only 2,471 had oxygen levels below 95.

Teams in every ward
"Particular attention was paid to those with low levels of oxygen. They were referred to COVID Care Centres if required. They are also being isolated before the symptoms appear, so there are not many problems during the treatment. The BMC has set up a monitoring team in each ward to monitor people with low levels of oxygen," said Dr Ramesh Bharmal, director of the major BMC hospitals.
