Public explainer
Plague is a bacterial infection caused by Yersinia pestis. It can spread through infected flea bites or contact with infected animal tissues. Pneumonic plague affects the lungs and can spread through respiratory droplets during close contact.
The current reports do not establish a confirmed plague outbreak in Russia. The ECDC assessed the risk to people in the EU as very low based on the limited information available. Follow reliable public health updates and avoid sharing unverified claims.
If you become seriously unwell after possible exposure in an affected area, seek urgent medical advice and explain your travel and exposure history.
Clinical notes
Recognise: bubonic disease may present with fever and a painful, swollen lymph node; pneumonic disease with rapidly progressive fever, cough and breathlessness; septicaemic disease with severe systemic infection or shock.
If plague is a credible possibility: isolate a patient with suspected pneumonic disease and use appropriate respiratory precautions. Urgently involve local infectious disease and microbiology specialists. In the UK, contact UKHSA’s Imported Fever Service and notify the local Health Protection Team as advised; plague is an urgent notifiable disease in England.
Testing and treatment: coordinate specimen collection and testing through specialist services. Do not delay specialist-directed empirical treatment while awaiting confirmation when clinical suspicion is credible.
These notes support learning; follow current local protocols and specialist advice. They are not a treatment protocol.
