🎉The new and improved CoVariants.org is here! 🎉 We're hoping to make this a one-stop location to track not only the 'headline' variants, but many different #SARSCoV2 mutations & variants that scientists are keeping an eye on. Let's take a tour of the site! 1/12

1/ 🧵 In 2025, EV-D68 did something unusual in Europe: most detected cases weren’t children, but adults, and one subclade, A2/D, took over! 🌍 New preprint with Robert Dyrdak & ENPEN colleagues in 13 countries. What we found (& what we don’t know yet): medrxiv.org/content/10.64898…

15/ I hope this work highlights that we can think we know a virus, & still be surprised by what we see in a season. The truth is, there’s much yet to be understood! These dynamics would be invisible w/o surveillance across ages, wastewater, whole genomes & VP1 - & data sharing!

1/ 🧬 A big #Pathoplexus milestone: you can now optionally include raw sequencing reads alongside your consensus sequences! Hosting raw reads alongside consensus data helps improve reproducibility & allow in-depth analyses. 📰 Read more: pathoplexus.org/news/2026-09…

I'm so incredibly proud of what we've built in these past two years! But I also can't wait to see what comes next - we've still got so much more do to! Happy Birthday Pathoplexus! 🎂

1/ 🎂 Pathoplexus turns TWO! 🎉 Two years ago we launched with an idea: what if pathogen data sharing put open access, speed, ease of use, & credit for data generators at its center? Here's what our community has built since: 📰 Read the full update: pathoplexus.org/news/2026-08…

On top, is a gold and white '2' candle that's lit. From the cake come strands of blue and gold, representing stylized DNA, network nodes, and ribbons representing credit and attribution.
