Covid-19 samples for new variants risks hurting its battle against a record surge of infections, with scientists warning the delays could damage everything from vaccine efficacy to effective hospital treatments.The South Asian nation has tested less than 1% of its positive samples, according to government data, compared to the U.K.
which has sequenced 8% of infections, and 33% in the last week, the Covid-19 Genomics U.K. Consortium said. The U.S. last month reported it was sequencing about 4% of its 400,000 weekly new cases, the Centers for Disease Control and Prevention noted.India reported more than 115,000 new daily infections on Wednesday, taking its tally of cases to 12.8 million, behind Brazil and the U.S.
