Maharashtra Chief Minister Uddhav Thackeray on Saturday said bringing the COVID-19 outbreak under control was a mammoth task which was achieved by the hard work of Corona warriors, but cautioned that the threat from the virus still existed.

Speaking at an event to mark the golden jubilee of Marathi newspaper ''Sakal'', the CM said the Dharavi pattern, which managed to rein in the pandemic in one of the world's densest urban settlements, had been appreciated across the world.
