What → happen → lab
The 28-year-old woman, Darya Shipilova, employed at a research institute in Siberia fell ill and died in undisclosed circumstances, prompting authorities to quarantine dozens of people and dispatch the head of Russia’s health watchdog to the Irkutsk region.
asserted
woman → employ → region
The woman worked at the anti-plague research institute in the city of Irkutsk, where the plague occurs naturally in wild animals.

Russia dismisses epidemic concerns
Meanwhile, Russia’s health regulator insists there were no risks of an epidemic breaking out in Siberia after the plague institute worker’s death.
asserted
epidemic → dismiss → death
Rospotrebnadzor, Russia’s health watchdog, said on October 7 that it was winding down precautionary measures it had put in place after concluding there was no risk of an epidemic.
asserted
it → say → epidemic
No cases of plague had been detected among anyone who had come into contact with the deceased worker, it said, while adding that 90% of those placed in quarantine had been released after nearly 5,000 lab tests had failed to detect any dangerous pathogens.
asserted
tests → detect → pathogens
When asked about a second person in Siberia allegedly falling ill, Kremlin spokesman Dmitry Peskov urged caution against using media reports as a reference for what was happening.

‘Causative agent behind death not known’
asserted
agent → know → death
A top official with the World Health Organisation (WHO) said it doesn’t know how the lab worker in Siberia died.

worker → say → Siberia
Maria Van Kerkhove, WHO director of Epidemic and Pandemic Management, said the UN health agency doesn’t know what the “causative agent’ was behind the woman’s October 2 death.

What is pneumonic plague, symptoms
Reports blamed the woman’s death on pneumonic plague — a less common but severe form of plague that can spread from person to person.
asserted
that → blame → person
Pneumonic plague causes a severe form of pneumonia, but recovery rates are high if it is detected and treated in time.
asserted
it → cause → time
The severe disease is less common than the better-known bubonic plague linked to the Black Death in the Middle Ages.
asserted
disease → know → Ages
Pneumonic plague and bubonic plague are caused by the same bacteria.
asserted
plague → cause → bacteria
The former is spread by respiratory particles while the latter is spread through bites from fleas that have jumped from infected rodents.
asserted
that → spread → rodents
Symptoms of pneumonic plague include shortness of breath and coughing-up blood, and they can occur in as little as 24 hours after exposure, according to the WHO.
uncertain
they → include → WHO
