A K Rawat, 58, had served at the hospital for 27 years NEW DELHI: To add to their woes about inadequate oxygen supplies in the past 18 days, Delhi hospitals have struggled with their staff being infected with Covid-19, in the process creating a work overload on the remaining medical teams. At Saroj Super Specialty Hospital in Rohini, surgeon A K Rawat, 58, succumbed to Covid, further burdening the facility that has already had to close its labour, cardiology and neurology departments due to the 86 medical and support staff testing positive. Other hospitals similarly told TOI about doctors and paramedics reaching a stage of utter exhaustion due to heavy workloads caused by truncated staff strengths. At least 317 people, including doctors and paramedic staff, have tested positive for the coronavirus in just four hospitals in the past month.
