As the screening of passengers coming to Mumbai at railway stations has not yielded the desired results, the Brihanmumbai Municipal Corporation (BMC) is now focusing on door-to-door surveys for TB and leprosy patients, to find those positive for COVID-19. After 11 passengers were found positive on Day 1 of the testing at railway stations, the number did not go beyond five in the next four days. Civic officials say this could either be a positive sign or passengers have found a loophole in the system.

The fear of COVID-19 transmission through reverse migration in the city has still not manifested, or at least the results of railway station screenings have depicted this. Only 20 passengers have been found positive even after the screening of more than 50,000 passengers on six railway stations.
