Healthcare workers enter a residential area in Mumbai on April 20, 2020.

Only Kerala has managed to slow down its rate of growth of COVID-19 infections substantially among major States and can be confident about arresting the spread because of an above-average testing rate. Uttar Pradesh & West Bengal have a higher rate of growth of infections and very low testing rates.

Doubling rates

The chart plots the doubling rate* (in the last 10 days for a State with more than 250 cases) and the tests per million people in that State. The greater the size of a circle, the higher the cases.

Doubling rates vs. test rates

* Doubling rate is the estimated number of days it takes for cases to double in a State. The higher the rate, the fewer the new infections in a State

Cases are growing quickly in Gujarat, Maharashtra and Rajasthan, but the high testing rates suggest that more infected people are being identified.

Infections in West Bengal, Bihar & Uttar Pradesh are growing  quickly but the test rates in these States are much below average.

Tamil Nadu, Jammu and Kashmir, Andhra Pradesh. & Delhi are also relatively better off in slowing down the rate of increase of infected cases. They also have high testing rates.

Cases are rising slowly in Telangana and Punjab, but with lower testing rates, these States are not out of the woods yet.
