Teams in the Democratic Republic of the Congo & Uganda have now shared the first sequences from the current Ebola (Bundibugyo virus) outbreak using Pathoplexus, just days after cases were confirmed.

Read more about the response to Bundibugyo virus here:

Pathoplexus | Ebola: Rapid response to the Bundibugyo virus outbreak in the DRC and Uganda

Pathoplexus is a new, open-source database dedicated to the efficient sharing of human viral pathogen genomic data, fostering global collaboration and public health response.

1/ ๐Ÿš€ Pathoplexus now supports Bundibugyo virus (BDBV), a species of Ebolavirus.

BDBV has been associated with past outbreaks of Ebola in the DR Congo and Uganda, and a case has been reported today during response to the current Ebola outbreak.

Nextstrain #ANDV trees updated with a few improvements:
- 2 outbreaks marked
- host scientific/common name added
- province now visible on map
- date colouring added

Here's a quick tour of how to change colours, geography & names!

Since launching support for the Andes virus species of hantavirus two days ago, we have already received submissions from four countries' sequencing teams. This is a testament to the rapid response of researchers, sharing real-time data. Read more in our news post: https://pathoplexus.org/news/2026-05-11-andes-virus

My ANDV #Hantavirus @nextstrain phylogenies now pull directly from @pathoplexus to incorporate all seqs

I'll continue to improve them, & will keep them updated
