Two U.S. intelligence agencies reportedly support the lab leak theory — with low-to-moderate confidence. No evidence has been shared. Scientists have strong evidence of animal spillover at a market.
Animals carry millions of pathogens. So it's a daunting task to find the one with the greatest potential to spark a pandemic. Now scientists are rethinking the way they hunt for that next new virus.
As we launch a series about spillover viruses — like SARS-CoV-2, which triggered a global pandemic, you may have a lot of questions. So do we — 7, to be exact, in the quiz below. See how you do.
For nearly three years, China has enforced incredibly strict rules to keep coronavirus transmission in check. But now they're facing a potentially deadly omicron surge.
New research points to a surprising way to stop spillovers of Hendra virus, which is harbored by bats. It's not often that it jumps to horses, then humans, but when it does, the result are brutal.
Sikhulile Moyo led the team that first identified omicron — and was dismayed by the world's reaction — blaming and blacklisting African nations. He's now a bit more optimistic.
"Ventilation is the way forward," says infectious disease doctor Abraar Karan of Stanford. Here's how to get better air flow at home, in schools and offices — even in gyms — to stave off COVID.
