Russia says no plague cases detected among contacts of deceased lab worker
Confirmed
In Short: A 28-year-old laboratory worker died in Irkutsk, Russia, raising concerns about a potential plague outbreak.

Russian officials have not confirmed that a 28-year-old laboratory worker, identified as Darya Shipilova, died from plague, despite initial speculation.
The Irkutsk Anti-Plague Research Institute of Siberia and the Far East, where Shipilova worked, has not linked her death to her work or plague.
According to the World Health Organization (WHO), Russia has reported no plague cases in the city of Irkutsk.
However, the WHO is awaiting confirmation from Russian officials about the pneumonia-causing pathogen that led to Shipilova's death.
Reuters could not establish whether this means plague can be ruled out in Shipilova's case.
The WHO said Russian health officials informed them that no case of plague has been recorded in Irkutsk.
Testing of Shipilova's close contacts, about 60% of whom have been tested so far, has identified two cases of COVID-19 and two cases of rhinovirus infection, but no other infectious diseases.
The Irkutsk regional branch of Rospotrebnadzor denied reports of enhanced sanitary-epidemiological measures and strict restrictions in the region, stating the situation remains stable.
Independent news outlets have reported that Shipilova died from pneumonic plague, but there is no official confirmation.
The WHO and other health organizations are urging Russia for more transparency regarding the case.
US President Donald Trump offered to help Moscow deal with the situation, while Secretary of State Marco Rubio warned that a potential outbreak could spread quickly.
The Irkutsk regional governor, Igor Kobsev, said no microorganisms linked to Shipilova's professional activities were detected in her body.
