The Times’ analysis, performed in consultation with more than a dozen experts, offers several possible estimates for the true scale of devastation in the country. India’s official statistics report 26,948,800 cases and 307,231 deaths as of Tuesday morning. Even in countries with robust surveillance during this pandemic, the number of infections is probably much higher than the number of confirmed cases because many people have contracted the virus but have not been tested for it. On Friday, a report by the WHO estimated that the global death toll of COVID-19 may be two or three times higher than reported. The undercount of cases and deaths in India is most likely even more pronounced, for technical, cultural and logistical reasons. Because hospitals are overwhelmed, many COVID deaths occur at home, especially in rural areas, and are omitted from the official count, said Kayoko Shioda, an epidemiologist at Emory University. Laboratories that could confirm the cause of death are equally swamped, she said.
