NEW DELHI (AP) — When Narayan Mitra died on July 16, a day after being admitted to the hospital for fever and breathing difficulties, his name never appeared on any of the official lists put out daily of those killed by the coronavirus.

Test results later revealed that Mitra had indeed been infected with COVID-19, as had his son, Abhijit, and four other family members in Silchar, in northeastern Assam state, on India's border with Bangladesh.
