Chinese researchers warn of new virus in pigs with human pandemic risk

  • A team of Chinese researchers looked at influenza viruses found in pigs from 2011 to 2018 and found a “G4” strain of H1N1
  • They said it has “all the essential hallmarks of a candidate pandemic virus,”

SHANGHAI: A new flu virus found in Chinese pigs has become more infectious to humans and needs to be watched closely in case it becomes a potential “pandemic virus,” a study said, although experts said there is no imminent threat.
A team of Chinese researchers looked at influenza viruses found in pigs from 2011 to 2018 and found a “G4” strain of H1N1 that has “all the essential hallmarks of a candidate pandemic virus,” according to the paper, published by the US journal, Proceedings of the National Academy of Sciences (PNAS).
Pig farm workers also showed elevated levels of the virus in their blood, the authors said, adding that “close monitoring in human populations, especially the workers in the swine industry, should be urgently implemented.”
The study highlights the risks of viruses crossing the species barrier into humans, especially in densely populated regions in China, where millions live in close proximity to farms, breeding facilities, slaughterhouses and wet markets.
The coronavirus that caused the worldwide COVID-19 pandemic is believed to have originated in horseshoe bats in southwest China, and could have spread to humans via a seafood market in Wuhan, where the virus was first identified.
The PNAS study said pigs are considered important “mixing vessels” for the generation of pandemic influenza viruses and called for “systematic surveillance” of the problem.
China took action against an outbreak of avian H1N1 in 2009, restricting incoming flights from affected countries and putting tens of thousands of people into quarantine.
The new virus identified in the study is a recombination of the 2009 H1N1 variant and a once prevalent strain found in pigs.
But while it is capable of infecting humans, there is no imminent risk of a new pandemic, said Carl Bergstrom, a biologist at the University of Washington.
“There’s no evidence that G4 is circulating in humans, despite five years of extensive exposure,” he said on Twitter after the paper’s publication. “That’s the key context to keep in mind.”


Pregnant mom, unborn child die in India

Pregnant mom, unborn child die in India

  • Devastated family mourn latest victim of health system struggling to cope with outbreak

NEW DELHI: The death of an expectant mom and her unborn child after 13 hospitals in one day refused to treat her has put India’s strained health care system under the spotlight.

The devastated husband and 6-year-old child of eight-month pregnant Neelam Singh, 30, are still struggling to come to terms with the “unwarranted loss” a month after her agonizing death in an ambulance outside a hospital in New Delhi.

With more than 100,000 coronavirus disease (COVID-19) cases in the Indian capital, Singh became another victim of a health system battling to cope with patient demand due to a lack of bed space and infrastructure.

That, however, has been little comfort for her family members who said they would never be able to overcome the trauma.

“Those 12 hours were the most traumatic experience of our lives, and we have to live with that trauma,” Shailendra Kumar, Singh’s brother-in-law, told Arab News on Tuesday. Singh had developed complications with her pregnancy on June 5, and Kumar said she was rushed to the same hospital in Noida, Uttar Pradesh where she had been going for regular checkups, but was turned away.

“Shivalik (hospital) gave no reason for refusing to admit her. Despite our pleadings, the hospital did not budge from its stand,” Kumar added.

A day-long ordeal ensued, with one hospital after the other unable to treat her. Eventually, she died in an ambulance some 35 kilometers away from her home in Khoda.

“I took her to 13 hospitals, both government and private facilities, and every one refused to admit her. The image of her writhing in pain will always haunt me,” said Kumar, who was accompanied by Singh’s husband. He added that the reasons provided varied from “high costs” to a lack of facilities.

“One hospital told me that I could not pay the high cost so better try my luck somewhere else. At Sharda Hospital in Greater Noida, I was asked to buy a coupon for COVID-19 treatment for 4,500 rupees ($60), which I did, but still, they refused her entry. It was not the loss of one life but two lives,” he said, referring to her unborn child.

He pointed out that the entire family was in a state of shock following her death with her husband “the worst impacted.”

Kumar filed a complaint against Shivalik and other hospitals but said so far “no action has been taken.”

A day after Singh’s death, the district magistrate of Gautam Buddh Nagar, which Noida falls under, ordered an inquiry and issued instructions for all hospitals “to admit patients regardless of the nature of the case.”

However, 20 days later, on June 26, a similar incident was reported in the Dadri area of Noida.

On that occasion, 21-year-old Robin Bhati had developed a fever, and relatives had taken him to a nearby hospital where a week earlier he had been admitted suffering from influenza. However, the hospital refused to admit him and referred him to a different facility.

Five hours and four hospitals later, a city hospital agreed to take him in, but by then Bhati was already seriously ill and hours later he died after suffering a heart attack.

“We don’t know whether he was a COVID-19 patient or not, but why should hospitals refuse to admit a patient in need of immediate attention,” his uncle Jasveer Bhati told Arab News. A number of the Noida hospitals which allegedly denied admission to Singh and Bhati refused to comment on the cases.

In a statement on Monday, the office of Noida’s chief medical officer said: “Strict instructions have been given to all the private and government hospitals to admit all patients showing COVID-19 symptoms.”

Dr. Loveleen Mangla, a pulmonologist working with Noida-based Metro Hospital and Heart Institute, said: “The government did not prepare itself to face this situation. Now the government is trying to create extra beds and medical facilities, but it’s late. They should have done this three months ago when the nationwide lockdown started.

“With the entire medical infrastructure overstretched and not many quality health workers available in the government hospitals, it’s a grim scenario now,” Mangla added.

With more than 723,000 COVID-19 cases on Tuesday, India is now the world’s third worst-affected country after the US and Brazil, with approaching 21,000 people losing their lives.

And the problem is not unique to northern India.

On Saturday, the southern Indian city of Bangalore reported the case of 50-year-old Vasantha, who was rejected by 13 hospitals before she was accepted by the K.C. General Hospital where she eventually died.

Lalitha, a relative of Vasantha, said: “Some hospitals said they didn’t have beds; some said they didn’t have COVID-19 testing facilities, and that way we lost critical hours. She died because of a problem with her respiratory system.”

Experts have questioned whether health care facilities in India are being overstretched purely due to the COVID-19 pandemic.

Dr. Anant Bhan, a Delhi-based independent researcher in global health, policy and bioethics, said: “Is there a real shortage of beds or is it the shortage caused by lack of efficient management? If the cases increase further, we might find it difficult to provide care.”
