Biosecurity depends critically on the early identification of novel pathogens.

Our international team developed a global multi-scale model of infectious diseases to evaluate the time to detection in aircraft wastewater vs. other surveillance modalities.

📢 Thrilled to see that our work on chikungunya virus (CHIKV) epidemiology in Brazil is out in @thelancetinfdis.bsky.social 🧵

we've missed you

Northward expansion of Aedes albopictus-associated arbovirus transmission risk in Europe Since 2007, outbreaks of chikungunya and dengue have become increasingly frequent and large scale in Europe. The frequency and size of these episodes suggest a concerning trend. In 2025 alone, there h...

Brilliant work by @cathalmills.bsky.social + many others

Rt measures how quickly a pathogen spreads and was central to understanding and controlling COVID-19. In our latest work, we extend this concept to vector-borne diseases, developing a new, renewal equation–based framework that links infection dynamics in humans and vectors.

From January to 8 October 2025, France (n = 700) and Italy (n = 353) have reported CHIKV cases widely across their territories. The increase in clusters coincides with global outbreaks and temperature anomalies in Europe.

The 16th Ebola Virus Disease Outbreak in Bulape Health Zone, Kasai, Democratic Republic of the Congo: A new spillover event from an unknown reservoir host Background The Democratic Republic of the Congo (DRC) is currently facing concurrent outbreaks including mpox, cholera and malaria (1-4). The Ministry of Public Health, DRC has declared the 16th Ebola...

Sequence data from the new Ebola outbreak in DRC suggests it is indeed a new spillover.

And just incredible to see the virus sequenced and the data publicly shared less than 24 hours after confirmation of the outbreak.
