The first Ebola case has been reported today in France. Our rapid risk assessment last month showed that France consistently ranked among the European countries at highest risk of importation if an Ebola case were to arrive in Europe from the ongoing Bundibugyo outbreak.

On May 22 WHO reported 1 more #hantavirus case linked to the MV Hondius, while some high-risk contacts are still being located. We estimated that heterogeneous isolation + uncertainty on pre-sympt transmission leave a non-negligible risk of secondary clusters. Work led by @eugeValdano.

Ebola : quel est le risque de propagation du virus au-delà de la RDC ?
L’estimation de la taille réelle de l’étendue de l’épidémie, tout comme le risque de dispersion dans la région et au-delà, met les chercheurs au défi d’une flambée épidémique aux multiples inconnues.

What we choose to implement - and when - matters. Our work shows that proactive screening strategies can reduce transmission by ~40% vs reactive responses. A key lesson for preparedness. In PNAS Nexus: ow.ly/cLnu50YCrcn

Great discussion with @billhanage.bsky.social and the audience at #ESCMIDGlobal2026 during our session “Pathogens and people: modelling epidemics for preparedness”. Strong focus on how to improve preparedness in collaboration with public health institutes - lots to take forward.
