One of the biggest misconceptions about Ebola is that it is primarily a hemorrhagic disease. It isn't. In the current Bundibugyo Ebola outbreak in the DRC, fever, vomiting, and diarrhea dominate at presentation, while bleeding occurs in only ~10% of patients. www.nejm.org/doi/full/10....

Global approaches to infectious disease surveillance and modeling - Nature Medicine
This Review discusses global approaches to infectious disease analysis and modeling, focusing on federated methods and addressing long-standing challenges in data interoperability, equity and trust.

The amazing teams around Dav Ebengo & Placide Mbala-Kingebeni, alongside the Institut National de Santé Publique and AfricaCDC have led an effort to improve understanding of the current #Bundibugyo Ebola outbreak. Data: github.com/INRB-UMIE/Eb... Dashboard: inrb-umie.github.io/EBOV2026_Epi...
Global approaches to infectious disease surveillance and modelling are complex in a fragmented world. We brought together an international team of researchers and policy makers to suggest a path forward using AI and federated/distributed frameworks. www.nature.com/articles/s41...
1/ The past 36 hours have been significant for the ongoing #hantavirus outbreak. I still think the risk is low, but we're almost certainly going to see more cases. Here's what I'm watching: 1. Three new positive individuals (French, US, Spanish). 2. Four viral genomes. 3. Ship fully evacuated.
1/ Yesterday I was more worried about #hantavirus than I am today. Why? Flight attendant who was exposed - Tested negative Viral genome - No concerning mutations Two Singaporean's exposed - Tested negative Data situation - We're tracking at Global.health (h/t @mugkraemer.bsky.social)
Two more passengers (one in France and one in the US) from the MV Hondius testing positive after being evacuated yesterday. All data here: github.com/kraemer-lab/...
