The Rwandan #Marburg outbreak was only confirmed last Friday & already it's the 3rd or 4th largest on record. Probably the 4th. Last year there were 23 suspect cases in Equatorial Guinea's outbreak; all died without testing so it was likely bigger. But just a little — & this isn't over.

Helen, what is your take on the suspected case in Germany? It's sending alarm bells off in my head but I would like to know your opinion on the risk level
