Russia Plague Scare Highlights Key Risks of Pneumonic Disease
Plague is an illness caused by a bacterium, and it can affect different parts of the body.
Bubonic plague often starts after a bite from an infected flea and can make lymph nodes swell painfully.
Pneumonic plague affects the lungs and can make someone very sick quickly.
It can also spread between people through droplets when an infected person coughs during close contact.
Reports from Irkutsk say a woman died and nearly 200 people are being monitored.
Officials have not confirmed that this is a widespread outbreak or that a laboratory accident caused it.
Doctors can treat plague with antibiotics, and exposed contacts may be monitored or given preventive medicine.
Fast detection and treatment can help reduce the danger.
Bubonic and pneumonic plague are forms of the same disease, caused by Yersinia pestis.
Bubonic plague usually follows an infected flea bite and commonly causes painful swollen lymph nodes.
Pneumonic plague affects the lungs, can progress quickly, and may spread through respiratory droplets during close contact.
A woman in Irkutsk reportedly died; reports say nearly 200 people are being monitored, while some hospitals were placed under quarantine.
A laboratory accident and a widespread pneumonic-plague outbreak have not been established; plague can be treated with antibiotics.
