 It takes quite a while for the rash to be seen in these cases. And we still don't know, as Jean-Claude said, we don't know how infectious this is before the rash presents. And of course, sometimes the rash isn't visible. And so we don't know what mild disease looks like and how infectious people are. And so there's a very high likelihood of people travelling between these countries, but also getting on planes. And so we do need to be careful.
