Mongolia dates completion of monitoring for all contacts to 7 October

In a release dated 9 October, Mongolia’s National Centre for Zoonotic Diseases dates completion of medical monitoring for all contacts to 7 October. It presents the information within cooperation with the Irkutsk Anti-Plague Institute. According to the release, no health changes associated with infectious disease were identified.

The centre reports no dangerous microorganisms in roughly 5,000 tests and no organisms linked to the employee’s work in her samples. It also relays that staff had not sought infectious-disease care during ten days and that two commissions found no accidents or violations while handling pathogens. The centre says an expert commission acting on instructions from the head of Rospotrebnadzor also confirmed the biosafety commission’s findings.

The centre’s earlier release dated 8 October reported that more than 90% of contacts had completed monitoring as of 7 October. The Russian statement relayed by Interfax on 7 October used the same wording. A Rospotrebnadzor statement on 8 October then reported completion for all contacts. Rospotrebnadzor is Russia’s Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing.

“More than 90%” does not itself exclude 100%. The difference is that the new Mongolian release explicitly dates full completion to 7 October, whereas earlier reports described a process nearing completion. The reviewed publications do not explain the dates or wording; agency correspondence and individual monitoring records are not attached.

These results are attributed to health authorities. The new publication establishes no new cause of Darya Shipilova’s death and contains no laboratory confirmation of plague. Russia’s statements dated 8 October and Mongolia’s 9 October appeal to verify information remain separate entries.
