Fears over a possible plague case have grown in Russia after a laboratory worker died, according to the report. The concern has been heightened by the fact that pneumonic plague can become life-threatening very quickly if it is not treated.
Experts, however, have urged caution and said the situation should not be overstated based on the available information.
No further details were provided in the source about the location, the circumstances of the death, or any official confirmation of plague infection.
