Maharashtra's death toll now stands at 51753, with the case fatality rate at 2.47 per cent, well above the national figure of 1.42 per cent.
Dr Sanjay Oak, who heads the coronavirus task force comprising senior specialist doctors constituted on April 13 last year, said the latest spike cannot be termed a "second wave" of the coronavirus pandemic.
"People are not following Covid-appropriate behaviour. They need to restrain themselves," he said.
Maharashtra Government's Principal Secretary (Health) Pradeep Vyas blamed people's "indiscipline and negligence" for the spike.
"There is laxity in following protocols. People are not adhering to Covid-appropriate behaviour," he said.
"Authorities have to tell people that coronavirus is still around and the masses should not be lax and negligent," Vyas said.
