Official case context

Country-reported case indicators

Democratic Republic of the Congo (DRC) headline indicators and health-zone charts are generated from the INRB/UMIE BDBV2026-Data repository, using the build-2026-07-04-df8b775 data build. Uganda case and death counts are parsed from the Uganda Ministry of Health Ebola Updates dashboard.

Regional Outbreak Context

There are 3 affected provinces in the DRC: Ituri, North Kivu, South Kivu. They form a contiguous cluster. Affected provinces border Uganda, South Sudan, Rwanda, Burundi, and Tanzania.

DRC headline indicators and confirmed health-zone breakdowns are sourced from the INRB/UMIE BDBV2026-Data repository.

Genomic surveillance context

Bundibugyo ebolavirus public sequence dashboard

In the DRC, scientists from the Institut National de Recherche Biomédicale (INRB) began sequencing immediately, and sharing interpretation through multiple channels such as LinkedIn (see post to the right) and Virological. Scientists at the Central Public Health Laboratory (CPHL), Kampala - Uganda have also completed sequencing and shared data. Sequence data from both countries is being shared in near real-time through Pathoplexus.

It is thanks to these scientists doing good work and sharing it rapidly that I am able to aggregate and share the visuals here. Thank you!

159 sequences from the current outbreak are available from 2 countries (Democratic Republic of the Congo and Uganda) with a collection-to-release turnaround time range of 1 -58 days (median 30 days) . Sequences from the current outbreak were submitted by Pathogen Genomic Lab, INRB (126), Central Public Health Laboratories, Uganda (19), Pathogen Genomic Lab (13), Charite Virology (1).

Phylogenetic context

The embedded Nextstrain build shows available Bundibugyo ebolavirus genomes with tips colored by outbreak. Explore the complete analysis in the full Nextstrain Bundibugyo ebolavirus build . For more information on how to interpret phylogenetic trees like the one below, see the Applied Genomic Epidemiology Handbook section on phylogenetic trees.

Restricted sequence data: This build includes some restricted sequences from Pathoplexus. Please see Pathoplexus SeqSet PP_SS_2047 for information about included sequences, and follow this virological post for more details on sequencing efforts.

Built from the GenomicEpi Ebola workflow, a fork of nextstrain/ebola.

This embedded view shows only the tree panel; use the full Nextstrain build for map, metadata, and other Nextstrain views.

Data use and acknowledgements

Acknowledgements

We gratefully acknowledge the authors, originating laboratories, and submitting laboratories of the genetic sequences and metadata for sharing their work. Please be kind and follow the data use terms applicable to each sequence, and err on the side of being collaborative.

Analysis

Our bioinformatic processing workflow can be found at github.com/genomicepi/ebola, which is a fork of github.com/nextstrain/ebola. The only modifications were to metadata, colors, and display defaults.

Underlying Data

This build uses Bundibugyo ebolavirus records shared through Pathoplexus. All sequences used in this build are available through Pathoplexus SeqSet PP_SS_2047.

Some data in this build may be RESTRICTED-USE, meaning use in preprints or publications is restricted. Please see the Pathoplexus Data Use Terms for more details.
