Twenty-eight of the 39 containment zones in Calcutta are from two boroughs that cover parts of Kasba, Tiljala, Patuli, Mukundapur in the south and Ultadanga, Beleghata, Kankurgachhi and Phoolbagan in the northeast.

The other zones include an apartment near Pantaloons store in Kankurgachhi, an apartment in Kankurgachhi Second Lane, a stretch near Miabagan slum on Beleghata Main Road and a stretch of Motilal Basak Lane in Phoolbagan.

The list of containment zones is updated every three or four days.
