Bengal had till Saturday recorded 287 confirmed cases, while Bihar had 83 and Odisha 60. “How many are tested reflects the contact-tracing efforts around already identified cases and whether all the contacts are tested irrespective of symptoms,” Bhatnagar said. The district, which had recorded 162 Covid-19 cases, had through contact tracing placed in home quarantine 17,373 people. Scientists say the hospital detection of Covid-19 is the first signal of undetected cases in the community. “Finding one Covid-19 case among severe acute respiratory infection patients could mean at least around 10 or more cases, symptomatic or asymptomatic, in the community,” Bhatnagar said.
