NEW DELHI (AP) — New Delhi has imposed a weeklong lockdown to prevent the collapse of the Indian capital’s health system amid an explosive surge in coronavirus cases. Authorities said Monday that hospitals have been pushed to their limit. In scenes familiar from surges elsewhere, ambulances catapulted from one hospital to another, trying to find an empty bed over the weekend, while patients lined up outside of medical facilities waiting to be let in. Ambulances also idled outside of crematoriums, carrying half a dozen dead bodies each. Just months after India thought it had seen the worst of the pandemic, an expert said the virus is now spreading at a rate faster than at any other time.
