The questions, as usual, are plenty and never too easy. Is the second wave over? When will the next wave of infections wash up ashore? Will it be as brutal as the previous one? How dangerous is the Delta plus variant? Take that first poser, for instance. The most likely answer: Yes and No. As Balram Bhargava, director general of the Indian Council of Medical Research (ICMR), put it at a press briefing in late June, the epidemic is under control in large parts of the country—about 535 districts at last count—where the test positivity ratio was less than 5 per cent. But not so in some pockets. “The second wave is not yet over in our country. We still have 75 districts which have more than 10 per cent prevalence,” he said. Averting a future wave, therefore, hinges on a variety of factors—foremost among them being Covid-appropriate behaviour and avoiding mass gatherings.
