U.S. HEALTH OFFICIALS MONITOR SUSPECTED PLAGUE DEATH IN SIBERIA

U.S. health authorities announced Tuesday they are following developments in a suspected pneumonic plague fatality in Russia's Irkutsk region, though they have stressed there is no broader danger to the United States.

A laboratory worker employed at the Irkutsk Anti-Plague Research Institute died after falling ill with pneumonia. Russian officials have not formally identified the cause of death, describing it only as pneumonia of undetermined origin. The CDC said in a statement: "At this time, there is no indication of a broader threat to the United States, but CDC and our interagency partners are prepared and will continue to monitor the situation closely."

The World Health Organization and European disease prevention agencies are also observing the case. At a UN briefing, WHO spokesperson Christian Lindmeier noted that no official cause had been established and that his organisation remained in contact with Russian health authorities.

Russian health officials reported that screening of people who had contact with the deceased found no dangerous pathogens. Among those tested, authorities identified two cases of COVID-19 and two of rhinovirus, but detected nothing else of concern. Medical follow-up for 60 percent of her contacts has concluded. Inspections of the research institute uncovered no incidents involving dangerous microorganisms.

The European Centre for Disease Prevention and Control reported no secondary infections and no pattern of person-to-person spread. The WHO's preliminary risk assessment rated the danger as moderate to low within the Irkutsk region, low across Russia, and very low for Europe.

Plague, caused by the bacterium Yersinia pestis, responds to antibiotic treatment, particularly if caught early, the CDC noted. The pneumonic form attacks the lungs and transmits between people through respiratory droplets during close contact. The CDC identifies rapidly developing pneumonia, fever, weakness, shortness of breath, chest pain and cough as typical symptoms. The agency stressed: "Pneumonic plague can spread person-to-person through respiratory droplets during close contact, which is why rapid identification and treatment of infected individuals, and monitoring of potentially exposed individuals, are important public health measures."
