On 30th April, My Father Tapan Roy Chowdhury was diagnosed with covid. On 8th may he was admitted to Shusrusa Nursing home. He got discharge on 19th may with low oxygen support. But we needed to re admit him  at Peerless Hospital on 23rd May. As he was not improving we shifted him to CMRI hospital under Dr. Raja Dhar. Presently he is in ventilator support with critically low blood pressure and very low urine output. He requires dialysis now. We need to Rs. 15,00,000 for further treatment. Please help us.
