Plague in Russia
Neither WHO nor Russian health authorities have reported a confirmed human plague case in Russia in 2026. One death in Irkutsk in October is unexplained: Russia told WHO it was not plague, and WHO says it has not received a diagnosis.
What's official
- Irkutsk, October 2026: 1 death, cause undetermined. Not counted as a plague case. Full timeline
- 2019–2025: Russia sent WHO no plague surveillance data for this period. WHO shows Russia as "no data," which is not the same as zero cases.
- WHO's latest assessment (October 10, 2026): no evidence of ongoing transmission, and no travel or trade restrictions advised.
