Strain updates follow circulating HA/NA clades chosen by WHO-linked meetings twice a year.
Darker cells mean a higher score for this topic on that metric.

Quick answers
Where should I start with Mutation and variants?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Mutation and variants?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Change & defence before English norms look universal.
Are the scores a ranking of Mutation and variants?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Mutation and variants to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
People are both habitat and filter. Antibodies and T cells that worked last year may bind a drifted surface less well.
Hospitals watch severity and occupancy; vaccine updates watch antigens. Those are different dashboards for the same evolutionary process.
Body interfaces
Prior COVID immunity
Infection and vaccination left a patchwork; later lineages were discussed for escape and residual protection.
Hospital load
A more transmissible lineage can fill wards even if average severity falls, because arithmetic is about totals.
Antiviral era
Drugs can select resistant subpopulations in treated patients; that is a stewardship story, not a recipe.
Travel and mixing
Air travel moves lineages between cities faster than 1918 ships did; names go global in weeks.
Language of fear
Calling every change a 'super strain' burns attention. Measured traits beat adjectives.
Personal decisions about illness belong with a clinician. This atlas explains vocabulary, not a care plan.

Antibiotic resistance
A shared drug budget under selection in hospitals, farms and wastewater — stewardship, not a lab manual.
Familiarity 85Vaccines and immunity
Antibodies, memory cells and community arithmetic — conceptual, not a prescription and not an anti-vaccine tract.
Familiarity 94Biofilms
Surface cities of microbes — plaque and catheters explain persistence, without a grow-your-own kit.
Familiarity 38Hygiene and balance
Clean water saves lives; missing old microbial partners is a separate, still-debated immune story.
Familiarity 70Horizontal gene transfer
Sideways DNA traffic — conjugation, transduction, transformation as names and history, not protocols.
