Why it matters

It is carried by Egyptian fruit bats and can spread to people after exposure in caves or mines where they live.

Common ground

So imagine the surprise of researchers when they monitored Python Cave in Uganda, a known Marburg virus reservoir, and found that, despite the danger, dozens of people were entering the site.
