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 role of climate variability in shaping the 2023/24 outbreak of Dengue in Brazil (📉 in north regions; 📈 in southern populous regions).

Brazil recorded the largest outbreak on record which coincided with the warmest ever reported temperatures in the Americas.

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.

Climate-sensitive disease data integration has been challenging due to variations in spatial & temporal resolution of inputs as well as multi-modality (satellite imagery, tabular, genomic..). We built a tool to makes it easier to perform data integration: wellcomeopenresearch.org/articles/10-...

So proud of Dr. Joseph Tsui, whom I had the great pleasure of co-advising with Oliver Pybus, for finishing his DPhil yesterday.

Many thanks also to his examiners, Mike Osborne (Oxford Computer Science) and Jess Metcalf (Princeton Ecology/Evolution).
