Russian health watchdog Rospotrebnadzor announced it was winding down precautionary measures after a 28-year-old laboratory researcher in Siberia died on October 2.
Authorities reported that nearly 5,000 laboratory tests failed to detect dangerous pathogens among quarantined contacts, and no cases of plague were identified.
The World Health Organization stated it could not make a full risk assessment due to insufficient transparency and information provided by Russian authorities.
