Indian hospitals hit with COVID 'tsunami'

Overwhelmed hospitals in India are begging for oxygen supplies as the country's coronavirus infections soars again in a "tsunami" of disease, setting a world record for cases for the third consecutive day.

Max Healthcare, which runs a network of hospitals in north India, on Saturday tweeted that it had less than two hours of oxygen left while Fortis Healthcare, another big chain, said it was suspending new admissions in Delhi.

"We are running on back-up, waiting for supplies since morning," Fortis said.

India is in the grip of a rampaging second wave of the pandemic, hitting a rate of one COVID-19 death in just under every four minutes in Delhi as the capital's underfunded health system buckles.

The government has deployed military planes and trains to get oxygen to Delhi from the far corners of the country and overseas including Singapore.

The number of cases across the country of around 1.3 billion rose overnight by 346,786, the health ministry said, for a total of 16.6 million cases, including 189,544 deaths.

COVID-19 deaths rose by 2,624 in the past 24 hours, the highest daily rate for the country so far. Crematoriums across Delhi said they were full up and asked grieving families to wait.

Hospitals in Delhi have gone to the city's high court this week seeking it to order the state and federal governments to make emergency arrangements for medical supplies, mainly oxygen.

"It's a tsunami. How are we trying to build capacity?" the Delhi high court asked the state and federal governments in response to this plea.

"You can't leave me in the lurch," a lawyer appearing for the Jaipur Golden hospital told the high court on Saturday, seeking its intervention.

The court asked the government to ensure supplies, as well to make security arrangements for medical centres amid people's desperation.

India surpassed the US record of 297,430 single-day infections anywhere in the world on Thursday, making it the global epicentre of a pandemic that is waning in many other countries.

The federal government had declared it had beaten back the coronavirus in February.

Health experts said India became complacent in the winter, when new cases were running about 10,000 a day and seemed to be under control. Authorities lifted restrictions, allowing for the resumption of big gatherings.

Others said it could also be a more dangerous variant of the virus coursing through India. It is the world's second most populous country and people live in close proximity, often six to a room.

Experts say the only way India can turn the tide is to ramp up vaccinations and impose strict lockdowns in the so-called red zones of high infection. It has opened up the immunisation program to all adults but faces a shortage.

India is using the AstraZeneca shot and homegrown Covaxin. It has also approved Russia's Sputnik V and has urged Pfizer Moderna and Johnson and Johnson to provide it with vaccines.
