Diwali celebrations in Mumbai without Covid-19 restrictions this year has resulted in the highest number of burn injuries due to `diyas` and firecrackers in the last five years, a senior health official said on Saturday.

Confirming the spike, Dr Sunil Keswani, plastic and cosmetic surgeon of the Navi Mumbai-based National Burns Centre said the number of patients received at the facility in four days was equal to the usual inflow of three weeks.
