(Seoul = Yonhap News) Reporter Kim Seung-wook = A pathogen leak occurred at a plague laboratory in Siberia, Russia, killing one researcher, CNN reported on the 4th (local time), citing the Russian state-run TASS news agency.
According to reports, this accident occurred at the Irkutsk Plague Research Institute located in the city of Shelekhov near Irkutsk Oblast.
The Consumer Protection Supervision Agency, a Russian state agency in charge of infectious diseases, announced on this day that a 28-year-old female researcher at the institute died after being diagnosed with pneumonia of unknown cause.
Authorities are currently conducting an investigation to determine the exact type of pathogen that was leaked.
Alexei Chidenov, head of the Republic of Buryatia, adjacent to Irkutsk Oblast, said the cause of death of the deceased researcher was "possible plague," adding that there were no outbreaks of plague in the Buryatia region.
When news of the accident became known, an aluminum factory near the research center issued instructions to all employees to wear masks as a precaution and asked them not to be disturbed.
However, CNN reported that the ripple effect appears to be expanding.
According to the local independent media outlet Lyudi Vaikala, about 200 people have been designated as quarantined and observed at Schelehof Hospital, where the deceased researcher was transferred, and there is also a maternity hospital in the city where quarantine measures have been imposed.
Gennady Onyshchenko, former head of the Consumer Protection Supervisory Service, said in an interview with TASS news agency, "It is highly likely that the infectious disease in question is not plague. Even if it is confirmed to be plague, it is unlikely to lead to a large-scale spread due to low temperatures."
Pneumonic plague is one of the three symptoms caused by the Yersinia pestis bacterium, and unlike other plagues that are transmitted through contact with fleas or animals, it can be spread from person to person through respiratory droplets (fine saliva droplets).
