Campaign Ambassador Amitabh Bachchan, who got infected with COVID-19 last year in August and was admitted to a hospital, shared his experience of fighting the disease under expert guidance and care. Lauding the spirit of healthcare workers, Mr Bachchan said, 'You cannot believe the kind of effort they all make to make you comfortable. They don't go home; 24 hour, round-the-clock, they are there in their suits, in their attire, attending to you.'
