India on Wednesday registered nearly 30,000 new cases and 582 more deaths, raising its total to more than 936,000 cases and over 24,000 fatalities.

The actual numbers, like elsewhere globally, are likely to be far higher due to limited testing and poor surveillance, experts say, reports AP.

A two-week lockdown that started on Thursday has been imposed in Bihar, an eastern state with a population of 128 million and a fragile health system.

Since Saturday, Bihar has recorded over 1,000 cases a day despite limited testing.

Nearly 2.5 million poor migrant workers who had been stranded during India’s initial lockdown of the entire country have returned to the state after losing their jobs in large cities.

In Bangalore, a key technology hub in southern India where offices for major tech companies like Amazon and Apple are located, the government ordered a weeklong lockdown from Tuesday evening.

The initial boost that India’s economy received in June after the nationwide lockdown was relaxed is being halted by these localised lockdowns in high-risk areas, experts say. Economic indicators like labour participation rates and electricity consumption are down this month compared to June, according to the Center for Monitoring Indian Economy, an independent think-tank.

India’s minister for small and medium businesses, Nitin Gadkari, said last week that experts were predicting a loss of $133.3 billion in the next year.

Authorities are now increasingly trying to focus their lockdowns to shield the economy from further losses, and nearly a dozen states are turning to localised clampdowns in areas where many cases have been detected. Referred to as “containment zones” by public health officials, these can be as small as a few houses on a street in New Delhi, the capital.

Jayaprakash Muliyil, an epidemiologist at Christian Medical College in southern India, warned that the country's actual death toll from the coronavirus could be much higher due to the absence of a robust mechanism to report deaths in rural areas.

 “We don’t have the infrastructure,” he said.

Dr Ashish Jha, director of Harvard’s Global Health Institute, said that with new cases accelerating, India’s strategy must focus on keeping case numbers as low as possible and saving as many lives as it can.

“The standard stuff is the standard stuff: You have got to continue testing and isolation ... make sure there are few to no indoor gatherings,” he said.

Jha warned that India has to ensure it continues acquiring supplies and has enough beds for people who will need to be hospitalized in the coming days. “You can’t overprepare,” he said.
