India infections top 18 million as gravediggers work round the clock

India reported 379,257 new infections and 3,645 new deaths on Thursday, health ministry data showed, the highest number of fatalities in a single day since the start of the pandemic.

The world's second most populous nation is in deep crisis, with hospitals and morgues overwhelmed.

Mumbai gravedigger Sayyed Munir Kamruddin, 52, said he and his colleagues were working non-stop to bury victims.

"I'm not scared of COVID, I've worked with courage. It's all about courage, not about fear," he said. "This is our only job. Getting the body, removing it from the ambulance, and then burying it."

Each day, thousands of Indians search frantically for hospital beds and life-saving oxygen for sick relatives, using social media apps and personal contacts. Hospital beds that become available, especially in intensive care units (ICUs), are snapped up in minutes.

"The ferocity of the second wave took everyone by surprise," K. VijayRaghavan, principal scientific adviser to the government, was quoted as saying in the Indian Express newspaper.

"While we were all aware of second waves in other countries, we had vaccines at hand, and no indications from modelling exercises suggested the scale of the surge."

India's military has begun moving key supplies, such as oxygen, across the nation and will open its healthcare facilities to civilians.

The oxygen crisis is expected to ease by mid-May, a top industry executive told Reuters, with output rising by 25% and transport systems ready to cope.

"My expectation is that by the middle of May we will definitely have the transport infrastructure in place that allows us to service this demand across the country," said Moloy Banerjee of Linde Plc, India's biggest oxygen producer.

Hotels and railway coaches have been converted into critical care facilities to make up for the shortage of hospital beds.

India's best hope is to vaccinate its vast population, experts say, and on Wednesday it opened registration for all above the age of 18 to receive shots from Saturday.

But although it is the world's biggest producer of vaccines, India does not have the stocks for the estimated 800 million now eligible.

Many who tried to sign up for vaccination said they failed, complaining on social media of being unable to get a slot or even to simply get on the website, as it repeatedly crashed.

"Statistics indicate that far from crashing or performing slowly, the system is performing without any glitches," the government said on Wednesday.

More than 8 million people had registered, it said, but it was not immediately clear how many had got slots.

A local official in Mumbai said the city had paused its vaccination drive for three days as supplies were running short, while officials said the worst-hit state of Maharashtra was likely to extend strict coronavirus curbs by another two weeks.

Only about 9% of India's population of about 1.4 billion has received a dose since the vaccination campaign began in January.

However, while the second wave overwhelms the health system, the official death rate is below that of Brazil and the United States.

India has reported 147.2 deaths per million, the Reuters global COVID-19 tracker shows, while Brazil and the United States reported figures of 1,800 and 1,700 respectively.

However, medical experts believe India's true COVID-19 numbers may be five to 10 times greater than the official tally.

At Delhi's Holy Family Hospital, patients arrived in ambulances and private vehicles, some gasping for air as their oxygen cylinders ran out. In the ICU, patients lay on trolleys between beds.

"Someone that should be in the ICU is being treated in the wards," Dr Sumit Ray, head of the unit, told Reuters.

"We are completely full. The doctors and nurses are demoralised, they know they can do better, but they just don't have the time. No one takes a break."

The U.S. State Department issued a travel advisory on Wednesday against travel to India because of the pandemic and advised its citizens to leave the country. Family members of U.S. government employees in India can voluntarily return to the United States, it added.

Prime Minister Narendra Modi has been criticised for allowing massive political rallies and religious festivals which have been super-spreader events in recent weeks.

India expects close to 550 oxygen generating facilities from around the world as medical aid starts pouring in, Foreign Secretary Harsh Vardhan Shringla said on Thursday.

Two planes from Russia, carrying 20 oxygen concentrators, 75 ventilators, 150 bedside monitors, and 22 tonnes of medicine, have arrived in Delhi.

The United States is sending supplies worth more than $100 million, including 1,000 oxygen cylinders, 15 million N95 masks and 1 million rapid diagnostic tests, the White House said on Wednesday.

The United States also has redirected its own order of AstraZeneca manufacturing supplies to India, to allow it to make more than 20 million doses, the White House said.

India will receive a first batch of Russia's Sputnik V vaccine on May 1. Russia's RDIF sovereign wealth fund, which markets Sputnik V globally, has signed deals with five Indian manufacturers for more than 850 million vaccine doses a year.

Bangladesh said it would send about 10,000 vials of anti-viral medicines and 30,000 PPE kits.
