White House Monitoring Reported Plague Case and Quarantine in Russia

A suspected case of pneumonic plague has emerged in Russia, drawing attention to this serious bacterial disease. The incident involves a 28-year-old laboratory worker at an anti-plague research institute in Irkutsk, Russia, who passed away on October 2 after developing pneumonia. Authorities suspect the woman may have contracted pneumonic plague after accidentally breaking a test tube containing Yersinia pestis, the bacterium responsible for plague, on September 25.

However, Russian health officials have not confirmed her diagnosis or linked the illness to the laboratory accident.

Russian health watchdog Rospotrebnadzor has classified the woman's condition as "pneumonia of unknown aetiology" and stated that tests did not detect bacteria associated with her work. Meanwhile, nearly 200 people who may have had contact with the deceased woman are under medical observation, with no signs of illness reported thus far. The US State Department is keeping an eye on the situation and collaborating with the CDC and other agencies.

Pneumonic plague is a severe form of the bacterial disease caused by Yersinia pestis. It primarily affects rodents and can spread to humans through flea bites, contact with infected animals or their tissues, and inhalation of respiratory droplets from an infected person or animal. In contrast to the other forms of plague—bubonic and septicemic—pneumonic plague can be transmitted directly from one person to another.

Symptoms of pneumonic plague include fever, headache, weakness, cough, shortness of breath, chest pain, rapidly progressing pneumonia, and bloody or watery sputum. Diagnosis and treatment are critical, as the disease can become life-threatening rapidly if left untreated. Antibiotics are effective in treating pneumonic plague, especially when administered early.

However, prompt treatment is essential, as untreated pneumonic plague can lead to death within 18 to 24 hours after the onset of symptoms. Close contacts of a suspected pneumonic-plague patient may receive preventive antibiotics to mitigate the risk of infection.
