Plague Spreading?

I'm seeing some reports that indicate that the number of hospitals placed under quarantine is now five. The Daily Mail also reports on the international response:

    Foreign states have now tightened border health controls despite Russia insisting the anti-plague scientist died from 'unidentified pneumonia', rather than the suspected 'Black Death' bacterium. 

    US Secretary of State Marco Rubio said today that Washington is monitoring reports of a plague infection but that it is not a 'cause for alarm'.

    'There's very limited travel between the US and Russia, obviously, but like anything else, something like that gets out, it could quickly spread,' Mr Rubio told reporters before taking off on a visit to Iceland.

    'So we're watching and monitoring it closely. I don't think it's cause for alarm, but it is cause for focus and a cause to just keep an eye on it. And we're doing that.'

    The Putin regime is seeking to downplay Ms Shipilova's death on October 1, yet widespread suspicion of a state cover-up is rapidly spreading.

    It was revealed today that more than 60 colleagues of the young scientist will remain locked inside her Siberian research institute for days, sleeping on floors and chairs despite none testing positive for the plague. 

    Up to five hospitals in and near Irkutsk are in 'epidemic' mode, according to reports, with hundreds of staff and patients not allowed to leave. 

    City Clinical Hospitals No1, No3, and No10 and the Ivano-Matreninskaya Children's Hospital have been closed for a three-week quarantine, according to Lyudi Baikala.

    Relatives of a woman giving birth at one of Irkutsk's maternity hospitals also reported to the outlet that it had imposed a quarantine. 

    A source in the healthcare sector told the publication that Irkutsk doctors are 'openly talking about plague'.   

Besides the official story of the cause of her death changing, Russia is insisting that people only trust official sources of news. This even as the government denies quarantines at hospitals that have clearly been isolated.
