Two Viruses Pose Global Pandemic Risk

Scientists have found two new viruses that could cause a big sickness around the world.

Many cow workers in Colorado and Florida have been exposed to these viruses, but they don't get sick.

This is worrying because if these viruses change and can spread easily from person to person, they could cause a lot of people to get sick.

Most people don't have protection against these viruses, so it's important to keep studying them.
