Russia's health authorities say there is no risk of an epidemic after a laboratory worker at a plague research institute in Siberia died last week. Around 200 people who had contact with the woman have been monitored, with the WHO saying none had developed symptoms so far. Russian officials said testing had found no signs of dangerous pathogens among those being monitored and that measures had been put in place as a precaution. The circumstances and cause of the worker's death have not been publicly detailed, while Russian authorities have pushed back against reports suggesting a wider outbreak. #russia #plague #siberia #health #news
