MOSCOW: Russian authorities denied Tuesday (Oct 6) that they were imposing anti-plague measures after a laboratory technician reportedly died of the disease, as Washington called on Moscow to be "transparent" about the situation.

It was reported last week that a worker at an anti-plague institute in Siberia's Irkutsk region died of pneumonic plague.

But the authorities say the cause of death is not confirmed and health watchdog Rospotrebnadzor has denied claims circulating in a document online that special measures had been put in place.

"We wish to clarify that the document and information in question do not originate from official sources and are untrue," it said on Telegram.

Russian news outlet People of Baikal reported on Friday that the dead woman - named as 28-year-old Darya Shipilova - may have contracted pneumonic plague from a broken test tube.

Other media reported a possible link between her death and a lab accident at the facility.

The People of Baikal outlet also said up to 200 people with whom she may have had contact were under quarantine.

"LOW RISK"

But Russian officials said postmortem tests had not detected the disease.

Irkutsk Regional Governor Igor Kobzev said Monday that a Rospotrebnadzor inspection had found the woman died of pneumonia and the cause was "undetermined".

"No microorganisms linked to the young woman's professional work were found in her biological samples," he said, adding that no other staff at the institute had sought medical attention since her death.

The World Health Organisation said that an update received Tuesday from Russia stressed that "no case of this dangerous disease has been recorded in the city of Irkutsk".

The update said Russia had launched an epidemiological investigation into a "case of community-acquired pneumonia" in an employee at the Irkutsk institute, and had identified contacts and made arrangements for medical monitoring and laboratory testing.

"Test results showed no presence of dangerous infectious disease pathogens in any of the contacts," the update said, according to WHO.

Based on the information currently available, the United Nations health agency "estimates the risk to be moderate to low for Irkutsk", spokesman Christian Lindmeier told a press briefing in Geneva.

He said the risk was low for Russia as a whole, and very low for the rest of Europe.

Nonetheless, he stressed that the United Nations health agency was monitoring the situation closely and was seeking to verify the event and the laboratory tests.

Plague is a bacterial disease that can occur in several forms, including pneumonic plague, which is the most contagious type and can be transmitted by respiratory means. Bubonic plague is transmitted by infected fleas.

Pneumonic plague, which causes lung failure, can be fatal if not treated early, according to WHO.

RUSSIA MUST BE "TRANSPARENT"

US Secretary of State Marco Rubio demanded Tuesday that Russia be "transparent" about the situation, which he said Washington was monitoring "very closely".

"I think it's incumbent upon Russia to obviously share more information with the world," Rubio said during a trip to Iceland.

US President Donald Trump had said Monday that his country was looking at the situation "very strongly" and would "help them as much as we can".

In an apparent response to Trump's offer, Rospotrebnadzor on Tuesday announced that Russia was prepared to assist the United States in combating its own outbreaks of infectious diseases.

"The situation regarding dangerous infectious diseases remains unstable," it said, highlighting among other things a "significantly worsened" measles situation in three US states, and a "fatal case of plague" recorded in New Mexico in June.

Russia, it stressed, was "prepared to provide the US side with specialists, laboratory equipment and highly effective diagnostic and preventive tools".

An international conference on plague and other infectious diseases will meanwhile be held in Irkutsk on Oct 21-22.

The conference was arranged in June and organisers said it was "unrelated to the recent death of an employee of the anti-plague institute".
