The sharp spike in cases can be attributed to the higher testing levels in the second wave compared to the first
The second wave of COVID-19 cases in India and especially Maharashtra appears to be quicker than the first wave. However, the sharper spike can be attributed to the higher testing levels in the second wave compared to the first. In the graphs, days taken for a select number of cases in the second wave are compared with the days taken for a similar number of cases in the first wave. The number of COVID-19 tests conducted during the two time periods was also analysed.
