Embassy personnel and their families in Russia are generally advised to avoid contact with rodents, marmots, fleas, and other wild animals in plague-endemic regions, steer clear of raw or undercooked game meat, use insect repellent, and seek immediate medical care for sudden fever, chills, or swollen, painful lymph nodes. Guidance also typically covers limiting travel to affected areas, reporting suspected exposures promptly, and knowing that plague is treatable with antibiotics when caught early. There are several important details, including exposure risks and warning signs, that vary by region and situation, so see below to understand more. Because plague symptoms can mimic flu, strep, or other common infections, guessing can delay care that is most effective within the first 24 hours. If you have fever, body aches, or swollen glands and are unsure how worried to be, take a free, instant, online symptom check to see what your symptoms may mean and what sensible next steps look like.

Bubonic plague
– Most common form.
– Transmitted by infected flea bites.

Septicemic plague
– Occurs when bacteria multiply in the bloodstream.
– Can develop from untreated bubonic plague.
– Symptoms: abdominal pain, shock, bleeding into skin and organs.
Pneumonic plague
– Most serious form; affects lungs.
– Can spread person-to-person via respiratory droplets.
– Symptoms: high fever, cough, difficulty breathing, chest pain.
Without prompt treatment, pneumonic plague can be fatal within 24–48 hours of symptom onset.
