The pandemic state of emergency was lifted but there are still plenty of viruses to worry about. Here are some highlights of our viral coverage this year, including NPR's "Hidden Viruses" series.

Two scientists, one Nigerian and one American, created a cutting-edge surveillance network to catch the next emerging disease before it becomes a pandemic.

Pigs and goats likely catch it too. It's been found in humans' noses in the Southwest — and in the air at airports and at chicken farms in Malaysia.

In response to our series on spillover viruses, you had many questions: from the role of climate change to possible benefits. We turn the mic to you for a special edition of 'Hidden Viruses.'

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.

Since the pandemic was declared in 2020, many perhaps unfamiliar terms have become part of daily conversation. Here's a glossary, from antibodies to zoonosis.

The South African-based scientist who co-discovered the omicron variant of COVID-19 makes an intriguing argument.

It was a big year for viruses, which simply refused to be ignored. And unlike the previous two years, COVID had to share the spotlight.

Wastewater testing has proved a reliable early alarm bell for COVID-19 outbreaks. U.S. researchers are now adapting the approach to track the explosive spread of monkeypox, and maybe other viruses.

The testing system set up by the CDC actually deters doctors from ordering a monkeypox test, and many physicians aren't familiar with the disease, resulting in too few tests and little tracking.
