India on Monday crossed the milestone of having conducted 110 million covid-19 tests, but public health experts warned this wasn’t enough and that India needs to scale up testing rapidly in order to control the pandemic. India’s rate of testing remains one of the lowest in the world. It conducts 82,032 tests per 1 million population, compared to 437,318 per 1 million in the US, 492,161 in the UK and 111,163 in China.
