Rospotrebnadzor said nearly 5,000 tests found no dangerous pathogens and saw "no epidemic risk," while the Kremlin called most media reporting "false" and said it had no knowledge of a US demarche formally requesting additional information.
Rospotrebnadzor said Darya Shipilova, 28, died of "pneumonia of unknown aetiology" with no links to her work at the Irkutsk Anti-Plague Institute, but imposed quarantine on her contacts, confined 60 colleagues inside the facility and restricted access to hospitals including a maternity ward.
Rospotrebnadzor said tests found no pathogen linked to the deceased lab worker's work at the Irkutsk anti-plague institute, but more than 60 colleagues remained isolated inside the building and several hospitals stayed closed without explanation.
A female staff member at an anti-plague institute in the Irkutsk region who died amid rumours of a "black death" outbreak was diagnosed with "pneumonia of unknown origin". Rospotrebnadzor insists that the situation in the region is "stable".
