🦟📄 New preprint! Our first large-scale phylodynamic study of Jamestown Canyon virus (JCV) reveals how mosquito ecology shapes the evolution, persistence, and spread of this understudied arbovirus in North America. Read it here! www.biorxiv.org/content/10.6...

Evolutionary history of Jamestown Canyon virus disentangles complex multi-vector ecology

Jamestown Canyon virus (JCV) is a re-emerging mosquito-borne virus of increasing concern in North America. It has been historically understudied, leading to significant gaps in our understanding of it...

Really great to see that our paper is now officially published in the latest #Eurosurveillance. As it was accepted with only minor edits, this earlier post still captures the key messages: tiny.cc/036u001.

In the COVID-19 Omicron surge, #KULeuven combined contact tracing with sequencing. Only 1/3 of contacts shared the same strain 🤯, so most people misperceived where they got infected. @thibaut-jonathan.bsky.social and team show how to assess contact tracing accuracy in the future! #IDSky #EpiSky
