The COVID-19 crisis in India continues to rage, as the nation of roughly 1.4 billion people set the global record for virus cases in a single day with more than 400,000 new infections reported Saturday. The true number of infections, however, is likely much higher than that, at least one expert says. Based on modeling from a previous surge in India, Dr. Prabhat Jha of the University of Toronto estimates the country’s actual COVID-19 caseloads could be as much as 10 times higher than the official numbers being released. On top of a skyrocketing case count, COVID-19 deaths in India have spiked sharply and vaccine rollout is still in its early stages, with less than 2% of the nation fully vaccinated. The new high in daily cases comes as President Joe Biden’s administration plans to restrict travel from the U.S. to India beginning Tuesday for virus concerns.
