Thin on the left so far
Only 1 of the 13 outlets with a published leaning rating that ran this story are rated left.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
The World Health Organization announced on Saturday that Russia's state health regulator had confirmed the death of a laboratory worker at a plague research facility in Siberia. Russia informed the WHO that no case of plague had been registered. The laboratory worker fell ill and died on October 2. Following the death, authorities placed about 200 people under quarantine. The cause of the worker's death remains unknown.
Disagreement on circumstances of death
The Star Kuala Lumpur reported that the laboratory worker died in undisclosed circumstances. Other reports did not specify the circumstances of the death.
What the coverage left out
None of the centre-rated or right-rated reports mentioned that the laboratory worker fell ill before dying. The cause of death was stated as unknown in all reports, but the fact that the worker became ill prior to death was not included in the centre or right coverage.

Questions about this coverage
- How did the left and right cover WHO confirms death of lab worker at Russian plague facility?
- Of the 13 outlets on this story carrying a published leaning rating, 8% are rated left, 38% are rated centre, 54% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 21. The sections above set out what each side emphasised, in its own terms.
- Is WHO confirms death of lab worker at Russian plague facility left or right?
- Neither side dominates it. Of the 13 rated outlets on this story, 8% are rated left, 38% are rated centre, 54% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of WHO confirms death of lab worker at Russian plague facility biased?
- WHO confirms death of lab worker at Russian plague facility is one event reported by 21 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting WHO confirms death of lab worker at Russian plague facility?
- When we first saw this story, outlets rated left had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
