Chinese scientists are now pleading for authorities to "urgently implement" measures to prevent the virus from spreading.
On Monday, Fauci also warned that the United States could see a surge in COVID-19 infections, up to 100,000 new cases per day, if the nation does not slow the ongoing virus outbreak.
The researchers expressed concern about a virus they called "G4". Pressure is now on to protect people who work with animals like pigs, with another study finding through antibody tests that more than one in 10 swine workers had already been infected. If further investigations reveal that G4 is indeed a communicable disease between humans, it has the potential to spread to the wider population via those working in such industries.
The study also focused on the possibility of viruses crossing the species barrier into humans, particularly in densely populated regions in China, where millions live in close proximity to farms, breeding facilities, slaughterhouses and wet markets. This new strain is called G4 EA H1N1, and it can grow and multiply in the cells lining the human airways. "There's no evidence that G4 is circulating in humans, despite five years of extensive exposure", said a biologist at the University of Washington, Carl Bergstrom, on Twitter, "That's the key context to keep in mind". According to the World Health Organization, most cases were mild, but "globally it is estimated that the 2009 pandemic caused between 100,000-400,000 deaths in the first year alone".
More meteors in the skies
But this week you might want to look to the skies as well - and feast your eyes on a luminous night sky. But they move quite quickly - "blink and you'll miss it", Lord warned.
