The reasons are too many! The state which was ruled by the Leftists for the last 35 years effectively destroyed two important fields in which West Bengal a very important place in India.Things reached such a point that D-category employees were allowed to dictate terms with superintendents of hospital.District and block-level hospital were made such dreaded placed even animals dread to visit them! Hopefully things are changing under the new regime!
Least facilities and equipment, lack of personal care and poor quality of medicines are few notable reasons.Apart from it, the entire team's carelessness can only lead to such a huge death toll.
I attribute it to the revolutionary mistakes committed by the Leftist leaders who made almost treated the hospitals as factories and the medical staff as factory workers and the result is for all to see!
