A more virulent strain of coronavirus, insufficient infrastructure to handle critical cases and hoarding of essential drugs has led to more deaths in Delhi, experts said on Tuesday. They also said the number of deaths could be more as many patients die outside hospitals waiting for a bed.

Dr Jugal Kishore, the head of community medicine at Safdarjung Hospital, said the "insufficiency of infrastructure" to handle critical patients is leading to more deaths. "The virus is not causing so many deaths, it is the insufficient resources and facilities. This is the major reason," he said.
