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.
