Kundan Punjabi has never had a worse time than the months of May and June this year. As the second Covid wave peaked, the Bhopal-based businessman lost five members of his family to the pandemic, including his brother. Among other things, Mr Punjabi pointed to a specific cause for the tragedy: "Had it not been the test results, my brother would have been alive with us. If the report came negative, what could we do? We believed he was not infected."
