Situational briefing

Background

The Irkutsk Anti-Plague Research Institute of Siberia and the Far East studies plague in natural foci across Siberia. A 28-year-old technician fell ill in late September and died on Oct 2. Reports differ on whether a lab accident or field trip was involved.

Transmission

Yersinia pestis spreads via flea bites from rodents (bubonic). Pneumonic plague is the only form that spreads person-to-person, through respiratory droplets during close contact.

Symptoms

Sudden fever, chills, headache, weakness, then rapidly developing pneumonia with chest pain, cough and sometimes bloody sputum. Incubation 1–4 days.

Containment

Treatable with antibiotics if started within ~24 hours. Contacts receive monitoring and preventive antibiotics; isolation, masks and droplet precautions limit spread.
