It's been 3 years since the World Health Organization declared that SARS-CoV-2 is a global health emergency. And scientists think it won't be the last virus that's going to confront the world.

In a new series, NPR is looking at the hidden viruses that could trigger the next pandemic. And even though we may think we're experts on the topic, there are some surprising twists in the story.

Take our quiz and test your knowledge.


Hidden viruses: how pandemics really begin

NPR is running a series on spillover viruses — that's when animal pathogens jump into people. Researchers used to think spillovers were rare events. Now it is clear they happen all the time. That has changed how scientists look for new deadly viruses. To learn more, we traveled to Guatemala and Bangladesh, to Borneo and South Africa.

We have a quiz for you to test your spillover knowledge. But we'd also like you to quiz us. Send your questions about spillovers to goatsandsoda@npr.org with "spillovers" in the subject line. We'll answer questions in a follow-up post when the series concludes in mid-February.
