With the immunocompromised status being a major risk factor for Covid-19, the Brihanmumbai Municipal Corporation’s (BMC) Tuberculosis department has been screening TB patients for the disease. Though Covid-19 has taken a toll on Mumbai, less than two per cent TB patients have been found positive in the past 18 months.

Since the pandemic started, BMC has tested 25,303 TB patients, out of which 452 were tested positive. Of these, 37 have died. Officials said they had adopted the bilateral testing policy with which they were able to identify TB patients with Covid-19.
