2nd Russian lab worker dies of plague
False
Accuracy: False. No. The supplied record confirms one death—lab worker Darya Shipilova—and says no Russian authority or WHO had confirmed a second fatality. Reuters likewise found no evidence a second person had died. The only support is an unverified media report of another death, and WHO’s inquiry concerned reports of a second employee with unexplained pneumonia, not a confirmed death from plague. Because there is direct counter-evidence and only unverified rumor on the other side, the claim is False. Verdict confidence: 90/100. The verdict is strongly supported because the supplied excerpts directly undercut the exact claim of a confirmed second Russian laboratory worker death from plague. The clearest passages say only one death was confirmed and that neither Russian authorities nor WHO confirmed any second fatality [S1P2, S1PF1]. Reuters also reportedly found no evidence that a second person had died [S2P3, S2PF1]. The only affirmative support for the claim is an explicitly unverified report that a second individual died, and even that excerpt does not firmly establish the person as a laboratory worker or plague as the cause [S3P1, S3PF1]. A remaining limitation is that several excerpts rely on official denials and incomplete public information while WHO was still seeking clarification, so the conclusion is based on absence of confirmation plus lack of evidence rather than a definitive disproval record for a Method: verdict-evidence-v1. Not a calibrated probability.
