Every sentence links to the reporting it rests on. The pill in front of each says where its sources sit: Left, Centre or Right when one side supplies at least half of them, Mixed when they are evenly split. The number is how many outlets it cites.

- Framing
- Hindustan Times carries an AP explainer on the outbreak's historic scale, causes and the CDC's limited role; Newsweek, in an AI-assisted piece, frames it as a map of rising CDC case counts across states.
- Emphasis
- AP stresses historical comparison, climate change and the 'new normal'; Newsweek stresses state-by-state increases and the CDC numbers.
- Leaves out or plays down
- Newsweek omits the death, the CDC's non-involvement and the historical comparisons; AP does not cover other states' increases.
- Charged language
- “breakbone fever”“the new normal”
