A 28-year-old laboratory technician, Daria Shipilova, who worked at the Irkutsk Anti-Plague Research Institute in Siberia, reportedly died on October 2 after being exposed to Yersinia pestis, the bacterium that causes plague. According to Barbara Friedman of Primedia+, Shipilova broke a test tube containing the bacteria, which led to her fatal exposure. The incident has raised concerns among international health officials, who are closely monitoring the situation.
The type of plague Shipilova contracted is believed to be pneumonic plague, which is more contagious to humans than bubonic plague. Pneumonic plague is transmitted through droplets spread by coughing and sneezing, making it highly contagious. In contrast, bubonic plague is typically spread through the bites of infected fleas or rats. Despite the risks, Friedman noted that pneumonic plague is treatable with antibiotics, and that Shipilova likely received a massive dose of the bacteria due to the test tube breaking.
In response to the incident, health officials have quarantined 198 people who were in contact with Shipilova. So far, none of those quarantined have shown symptoms of the disease. The Russian authorities have downplayed the incident, referring to Shipilova's cause of death as "pneumonia of unknown origin." However, Friedman emphasized that the situation is being closely watched by international health officials, who are taking precautions to prevent further spread of the disease.
The incident has sparked concerns about laboratory safety and security measures in place to handle potentially deadly bacteria like Yersinia pestis. Friedman noted that laboratories that work with such bacteria must take extensive precautions to prevent accidents, but that the risk of incidents like this one can never be completely eliminated. The incident has also raised questions about the handling and storage of such bacteria in laboratory settings.
The Irkutsk Anti-Plague Research Institute, where Shipilova worked, is a facility that specializes in researching and developing treatments for diseases like plague. The institute's work is crucial in the development of antidotes and treatments for such diseases, but it also poses risks to laboratory workers who handle the bacteria. The incident highlights the importance of ensuring that laboratory workers are properly trained and equipped to handle such bacteria safely.
The Russian authorities have not released detailed information about the incident, but international health officials are urging caution and vigilance in the face of potential outbreaks. The World Health Organization and other global health authorities are monitoring the situation closely, and are working with Russian authorities to prevent further spread of the disease.
The incident has also sparked concerns about the potential for similar incidents to occur in the future. Friedman noted that the COVID-19 pandemic has heightened concerns about laboratory safety and the potential for accidents involving deadly bacteria. As research continues into diseases like plague, the risk of incidents like this one will remain a concern for international health officials.
