Russian Plague Scare Raises Questions About India’s Risk
A laboratory worker in Russia died after becoming sick with pneumonia.
Officials have not said that she had plague, and tests reportedly did not find germs linked to her work.
Pneumonic plague is a serious illness that affects the lungs and can pass between people through droplets from a sick person’s cough.
The article says there is no reason for people in India to panic based on these reports.
The risk would be more concerning if confirmed cases began spreading from person to person.
Doctors can look for clues such as travel, animal or flea contact, or work in a laboratory.
If plague is suspected, quick testing, isolation and treatment can help protect patients and others.
A 28-year-old laboratory worker in Irkutsk, Russia, died after an illness authorities described as pneumonia of unknown cause.
Russian authorities said tests did not identify microorganisms associated with her professional activities; potentially exposed people were reportedly placed under observation.
The reports have not established that she had pneumonic plague or that an outbreak is occurring.
Pneumonic plague affects the lungs and can spread through respiratory droplets, but the article says the risk to people in India is virtually zero based on current reports.
Doctors are advised to consider travel, animal, flea, laboratory and contact exposures in rapidly worsening pneumonia; early recognition and treatment are important.
