Russian officials
Rospotrebnadzor (the health watchdog), Gov. Igor Kobzev, the Kremlin
Statements and their own tests · no documents released
They've put out statements and nothing else. No documents, no lab reports. On Oct 2 they only talked about "a particularly dangerous infection." By Oct 4 they had a formal diagnosis that wasn't plague, and from Oct 6 to 8 they released rising percentages of cleared contacts. The vaccination detail came last. Buryatia's leader changed his own account within hours, and Irkutsk journalists were told to clear their stories with the governor's press office (Novaya Gazeta).
Bottom lineIt's the authoritative record of what the state is doing. On what killed her, there's no way to check it.
Russian state media
RIA Novosti, TASS, Interfax, Rossiyskaya Gazeta
Official wording only
RIA and TASS put out every Rospotrebnadzor statement first and word for word. They stayed away from the word "plague" unless they were quoting Trump (Alexandra Arkhipova, Oct 6).
Bottom lineA reliable copy of the official line. Don't expect more.
Telegram tabloids
Mash, Baza, SHOT, Ostorozhno Novosti · channels with security-service ties
Unnamed sources
They were first to say pneumonic plague and first with the broken tube, both on Oct 2. They don't agree with each other on when she was admitted. One early version had her coming back from a work trip to Buryatia, and Buryatia's leader denied it.
Bottom lineTreat them as leads. Their track record mixes real leaks with noise.
REN TV
Pro-Kremlin television channel
Regional government figures
It published the detailed breakdown of 189 people in hospital (114 + 63 + 12), which suggests it had a real source. Then it deleted five posts.
Bottom lineThe deletion tells you more about the pressure than about the facts.
Lyudi Baikala
Independent Irkutsk outlet and Telegram channel · broke the story
On-record interviews + unnamed sources
It's the only outlet that talked to her mother, her colleagues, her neighbours and patients who were confined, and it got hold of the maternity ward's plague checklist. Its weakest claims are the FSB vehicles escorting ambulances and the three-week hospital closures. Both come from anonymous sources, and the closures are disputed.
Bottom lineThe best ground-level reporting there is. It's strongest on what people saw and weakest where it leans on unnamed officials.
The exile press
Meduza, Sibir.Realii (RFE/RL), The Insider, Novaya Gazeta Europe, The Moscow Times, Mediazona, iStories
Relays Lyudi Baikala + own reporting
Mostly they relay and extend Lyudi Baikala. Their own reporting includes the 60-plus staff locked in the institute (Sibir.Realii) and a running list of deleted posts (Current Time, The Insider). The Russian state calls them "undesirable," which cuts both ways.
Bottom lineCareful with details, and openly hostile to the official account.
World Health Organization
Tedros Adhanom Ghebreyesus, Maria Van Kerkhove, spokesman Christian Lindmeier
Russia's formal reply + media reports
It's working from Russia's formal reply and from media reports. On Oct 6 it put out a graded risk assessment "based on unofficial information": moderate to low for Irkutsk, low for Russia, very low for Europe. A day later it said it's "not able to conduct a full risk assessment." That was the biggest change of position all week.
Bottom lineThe only official body that's said plainly it doesn't know what killed her.
US government
White House, CDC, State Department
Little disclosed
The first word came from one unnamed official talking to Axios on Oct 4. The CDC's "extremely low" is based on travel numbers (about 200 travellers a year from Siberia, and no direct flights), not on case data. The Wall Street Journal broke the news of a formal diplomatic protest. Trump's "very deep discussions" and his bioweapon denial came with no evidence.
Bottom lineSolid on the risk to Americans. On what happened in Irkutsk, it doesn't know much more than the press.
European agencies
ECDC, UK Health Security Agency, European Commission
WHO channels and travel data
ECDC says it's "not yet confirmed," there are no secondary cases, and spread "generally requires close and prolonged contact." UKHSA puts the risk to the UK at "very low." The EU's Health Security Committee met on Oct 7 and hasn't published anything since.
Bottom lineThe most careful wording anyone's used.
Western wires
Reuters, AP, AFP
Russian media + officials, attributed
They've said "suspected" the whole way through and attributed every plague claim. Reuters is the only one that pointed out nobody's said whether she was tested for plague. AP's "100% cleared" got ahead of Russia's own numbers, and ABC and VOA got dates wrong.
Bottom lineThe safest summary, one step back from the ground.
Headlines & tabloids
Daily Mail, Newsweek, LBC and others
Framing
The headlines drifted all week, from "suspected case" to "outbreak" to "lab leak" to "biological agent." The Daily Mail's second death is the only claim that started in the West, and nothing backs it up.
Bottom lineThis is where the narrative lives. Check the second paragraph against the headline.
Independent experts
LSHTM, Northeastern, Johns Hopkins, MIT, Cambridge, Reading
Established science + inference
They agree on the disease. It incubates fast, spreads through close contact, responds to antibiotics and poses little risk abroad. They split on what Russia's response means, and the bioweapon talk rests on history.
Bottom lineTrust them on the biology. On the politics it's opinion.
