Lab Worker’s Death Raises Plague Fears in Siberia
A worker at a research institute in Siberia died after getting a kind of pneumonia whose cause was not known.
Some people worried that it might be a dangerous disease called plague.
Russian officials said the area’s health situation was stable and did not confirm that plague had been found.
A regional leader said the woman may have had plague, but said there was no outbreak in his region.
People who had close contact with the worker were being watched by medical staff.
A plant nearby told workers to wear masks.
News reports also said that nearly 200 people were being observed and that a maternity hospital had been quarantined.
Officials urged people to stay calm as the cause of the illness remained unclear.
A 28-year-old woman employed at the Anti-Plague Research Institute in Shelekhov died after being diagnosed with pneumonia of unknown origin.
Russian authorities said the sanitary and epidemiological situation in the Irkutsk region was stable and did not confirm that any infection had been released.
The head of neighboring Buryatia said the woman may have died of plague but stressed there was no plague outbreak in the republic.
Plant officials said identified close contacts were under medical supervision, had no symptoms, and tested negative; unofficial reports said nearly 200 people were under observation.
Precautions reportedly included mask use at a nearby aluminium plant and quarantine at at least one maternity hospital, while a former Rospotrebnadzor head said plague was unlikely.
