Parts of India have recorded dramatic falls in the number of deaths at a time when funeral parlours were bracing for a surge amid the coronavirus crisis.

Some experts said the trend suggested that deaths from Covid-19, which are recorded separately and generally announced before overall mortality data, were not being under-reported as has happened in other countries.

But emergency room doctors, officials, and crematoriums noted that strict lockdowns had cut the number of road traffic accidents and deaths on India’s packed railways, and may also be deterring relatives from reporting a family death.

All over the world, mortality rates are being scrutinised to determine the true impact of the coronavirus, which emerged in China late last year and is known to have infected more than 2.7 million people globally, with nearly 190,000 deaths.

While deaths in some countries have risen sharply in recent weeks, in India, where overall data is unavailable, the opposite seems to be happening in some places, leaving hospitals, funeral services and cremation sites wondering what is going on.

“It’s very surprising for us,” said Shruthi Reddy, chief executive officer of Anthyesti Funeral Services, which operates in Calcutta and Bangalore.

The company handled about five jobs a day in January but has had about three a day this month.

“We’ve declared employee pay cuts if revenue falls below a threshold,” Reddy said.

Other numbers tell a similar story.

Central Mumbai, home to some 12 million people, saw deaths fall by about 21 per cent in March compared with the same month of 2019, according to municipal data.

Overall deaths plummeted 67 per cent in Ahmedabad over the same period.

Data from at least two other cities, along with accounts from state health officials, show a similar pattern.

Half a dozen funeral businesses and crematoriums also reported slumps in business, especially in April.

“If we’re not seeing an increase in deaths, the suspicion that there may be more Covid-19 fatalities out there is not true,” said Giridhar Babu, professor of epidemiology at the Public Health Foundation of India.

Prime Minister Narendra Modi imposed a lockdown of India’s 1.3 billion people on March 25 in a bid to stop the spread of the coronavirus, which has infected some 23,077 people, killing 718, according to the latest figures.

India has tested about 525,000 people, meaning some 4 per cent were positive. In the US, about 18 per cent of tests are positive, according to the Covid Tracking project.

India’s apparently lower death rates stand in contrast to what has been seen elsewhere.

The Netherlands recorded about 2,000 more deaths than normal in the first week of April, for example, while in Indonesia’s capital of Jakarta the number of funerals rose sharply in March. Some towns in Italy also saw a jump in recorded deaths.

Indian doctors, officials and crematorium employees suspect the lower death rate is in large part attributable to fewer road and rail accidents.

“Road accident cases, and even patients with alcohol or drug abuse, stroke and heart attacks have been coming in fewer numbers,” said Himanta Biswa Sarma, health minister for Assam.

Accidents on India’s chaotic roads killed more than 151,400 people in 2018, according to official data, the world’s highest absolute number.

The coronavirus lockdown, which is due to end on May 3, will cut road deaths by at least 15 per cent this year compared with 2018, a transport official said.

With passenger trains halted, fatalities from all-too-common rail accidents have also plunged. In Mumbai alone, for example, more than half a dozen people typically die every day on the rail network.

Neeraj Kumar, who is in charge of a crematorium on the banks of the Ganga in Uttar Pradesh, said victims of crime were also not being brought in.

“We used to get at least 10 accident-related bodies every day and many related to murder cases. But after the lockdown, we’re only receiving natural death cases,” Kumar said.

The site used to perform up to 30 cremations a day but in the month since March 22, only 43 people had been cremated, Kumar said after leafing through the crematorium’s record book.

But the lower rates might also reflect difficulties in reporting deaths during the lockdown, officials said.

“There could be an increase when the lockdown ends,” said Dr Bhavin Joshi, a senior health department official with the Ahmedabad Municipal Corporation.

Requests for India-wide data from the national registrar went unanswered, while an official at the New Delhi Municipal Council said they could not provide numbers.

One outlier was Odisha, which recorded around 11 per cent more deaths in March 2020 than in the same month last year. Officials were not immediately available for comment.

Reuters was also unable to obtain data for Bengal, where some doctors have accused the government of understating coronavirus deaths. Only a state-appointed committee is allowed to declare that a patient has died from the virus.
