A reported pneumonic plague outbreak in Siberia, Russia, has triggered quarantines of about 200 people after a lab worker died, according to the Moscow Times. 

The Moscow Times reported: 

The woman was identified as Daria Sh., a 27- or 28-year-old employee of the Irkutsk anti-plague institute, by the exiled news outlet Lyudi Baikala (People of Baikal) and pro-Kremlin broadcaster REN TV.

She reportedly told medical staff that she had accidentally broken a test tube containing live bacteria while collecting samples for testing.
