LeftCenterRightLighter bar: this week so far

Each bar is the share of the outlets on our Left / Center / Right rating scale that we tracked publishing that week which carried reporting on this story, split by the outlets' ratings. We track more outlets now than in the archive, so a share keeps earlier and later weeks comparable. An outlet counts once a week however much it published, and outlets in one ownership or syndication group count as one on each side they appear on. A rating describes the outlet, not the report. A gap means no such reports were collected that week, not that nothing was reported anywhere. Weeks run Monday to Sunday in UTC, so a report published on a Sunday evening in US Eastern time counts in the next week. 10 more outlets off the scale (not rated, or outside the left-right graphs) also reported; they are not in this chart. See them.

    Mystery surrounds death of young worker at Russian laboratory

Background

The employee contracted pneumonia of an "unknown" cause and died, local state TV said. Russian authorities quarantined a hospital and monitored her contacts.[1] Unconfirmed media reports suggested she might have died of pneumonic plague, which is nearly always fatal without treatment, and some 200 people were placed under medical observation.[1][3]

Answers from Russia were slow to come. Russian authorities sought to allay global worries, and the Kremlin welcomed President Donald Trump's offer of help, while the World Health Organization said it had asked Russia for more information and was still waiting.[1] The Trump administration formally escalated its own request,[2] and the State Department warned Americans in Russia that it had "limited ability to help."[4]

In the US, between zero and 17 human cases were reported each year from 2000 to 2023, according to the CDC.[5]
