New strain of coronavirus discovered in Malaysia could be more infectious than COVID-19: Report – PennLive

There’s a newer strain of the coronavirus – it’s called D614G. Currently it’s making its way across southeast Asia, and the concern among Malaysian health officials is that it may be even more infectious than COVID-19.

KXAN Austin reported that “the strain has been seen in several countries across the continent and was originally found in a Malaysian cluster of 45 cases,” citing Bloomberg Quint, which follows international news out of India.

According to KXAN, health officials say “those 45 cases of D614G started after someone returned from India before completing his 14-day quarantine. Then, the strain was detected from several samples of COVID-19 in the Philippines.”

Philippines Health Undersecretary Maria Rosario Vergeire said on Monday that the mutation is said to have a “higher possibility of transmission or infectiousness, but we still don’t have enough solid evidence to say that that will happen,” KXAN quoted.

There is a lack of evidence.

According to the report, something health officials stress is the lack of evidence, with Benjamin Cowling, head of epidemiology and bio-statistics at the University of Hong Kong stating that “it might merely have a competitive advantage over other strains of COVID-19.”

The strain “might be a little bit more contagious,” Cowling told Bloomberg Quint. “We haven’t yet got enough evidence to evaluate that, but there’s no evidence that it’s a lot more contagious,” KXAN cited.

The report said that currently D614G is being studied in the Phillippines, where the outbreak of COVID-19 is highest in the region. According to the report, the World Health Organization says the mutation is the predominant strain in Europe and the U.S.

Dr. Anthony Fauci, the U.S. government’s top infectious disease expert, said back in July that a new mutation of COVID-19 could help coronavirus replicate more easily.

Fauci said, “It does look like a particular mutation may make the virus more transmissible,” the report quoted.

If the coronavirus wasn’t bad enough, a new flu strain shows ‘hallmarks’ of next pandemic – nj.com

Researchers are monitoring a new flu strain that has emerged in China, which they say has the features of a “candidate pandemic virus.”

It’s called G4 EA H1N1 and is carried by pigs in Asia. It’s a new strain of H1N1, or swine flu, which caused the 1918 and 2009 flu pandemics.

While experts say there is no cause for alarm at this point, a recent study in the U.S. scientific journal PNAS said, “G4 viruses have all the essential hallmarks of a candidate pandemic virus.”

Pigs are incubators for the flu — or “mixing vessels,” as the researchers put it — allowing them to generate pandemic-level flu viruses.

Some pig farm workers — about 10% of those studied — turned up positive for antibodies for the new flu strain, but didn’t fall ill because the virus is still unable to cause disease.

But researchers said the strain “has acquired increased human infectivity,” which signals that it’s learning how to better survive in people, said David Cennimo, an infectious disease expert at Rutgers New Jersey Medical School.

“I think the concern is, it is adapting better to being in humans,” Cennimo said.

Such an ability to establish infection “greatly enhances the opportunity for virus adaptation in humans and raises concerns for the possible generation of pandemic viruses,” the study said.

But Cennimo emphasized there is no reason to panic.

“I think the concern is more academic,” he said. “This is not raising a health alert or anything else.”

If the strain developed into a communicable disease, that’s when the alarm bells would ring.

“You’d be worried if these pig farmers were actually getting sick” and then transmitting it to others, Cennimo said.

That remains a concern, the researchers said in the study.

A pandemic from a new flu strain would magnify the coronavirus pandemic, which has shown no signs of slowing in the U.S. In fact, the crisis has only been ramping up in recent weeks in states throughout the country, especially in the southern and western regions.

Only time will tell what the new flu strain develops into. Health experts are continuing to monitor the situation in China.

The study said, “close monitoring in human populations, especially the workers in (the) swine industry, should be urgently implemented.”

Though the situation is still being investigated, Patty Olinger, an infectious disease expert, said the study has caught the attention of health experts around the country and the globe.

“It’s one of the reports you really pay attention to…” said Olinger, who is also the executive director of the Global Biorisk Advisory Council. “When we see these events, when there is a jump from one species to another, you start paying attention.”

She said whenever you see a novel virus that “has at least made it to humans but hasn’t caused disease, it makes you pause and take a look at it.”

But even if the new strain ends up being harmless, Cennimo said just a moderately severe flu season could disrupt the health care system amid the ongoing coronavirus pandemic.

Experts call it surge capacity, and a moderate flu season could spell disaster for hospitals in the state still coping with COVID-19.
