The chance to tame Covid-19 pandemic squandered after a good start

Adaptive Control model suggests India had shown improvement in the second week of August, but lost the opportunity later

A data-driven statistical model for Covid-19, which goes by the name Adaptive Control, has shown that India was successful in controlling the spread of infection in the second week of August. But the spread of the disease has worsened once again in the third week and on, and the situation remains critical once again after a brief period of control, the model indicates.
