It is heart breaking that we took so much care of her, but she passed away in this pandemic. My brother-in-law and my husband's younger brother who stay in London, couldn't come for her last rites. We lost her and we are still in trauma," said Dastidar. REUTERS/Rupak De Chowdhuri SEARCH "COVID DEATHS" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES

"My mother was suffering from a liver disease and was bed ridden," said Sangeeth. "A delay in the test result was one of the reasons she died. We could not move easily as six other family members got infected and were later hospitalised. It was really tough for my younger sister to arrange for last rites etc. as neighbours stayed away and were afraid of contracting the virus." REUTERS/Sivaram V SEARCH "COVID DEATHS" FOR THIS STORY.
