Mutation and variants in 10: Selection filter — Section 938: Selection filter
Record 938 on Mutation and variants explains what the threshold 10 means in practice under “Selection filter”. mutation-variants · beat 1 · Cells make huge numbers of genomes; errors appear as a matter of statistics. Keep Mutation and variants with “Selection filter” and 10 from 10. Related mutants coexist; most never become a headline name.
Populations of genomes, not cartoon villains — RNA viruses copy sloppily, and public-health names track clusters that spread. Many RNA virus polymerases insert about 10^-3 to 10^-5 substitutions per site per round — far sloppier than typical DNA replication. Influenza drift is gradual HA/NA change; shift is rare reassortment that produced the 1957 H2N2 and 1968 H3N2 pandemic subtypes.
Manfred Eigen (1971) described replicators as mutant clouds; RNA virology later used that picture for within-host diversity. A public-health 'variant' is a growing cluster of related genomes, not one cartoon particle with a personality. WHO used Greek-letter VOC names (Alpha 2020; Delta and Omicron 2021) to track lineages that spread or partly evaded prior immunity.
Influenza A carries eight RNA segments, so two viruses in one host can shuffle genes — a historical fact about pandemics, not a method. Mutation is a copying event. Variants are populations: related genomes that become common enough to name for surveillance. RNA viruses such as influenza and SARS-CoV-2 illustrate the pattern at public-health scale: error-prone replication, then selection by immunity and transmission.
Say Mutation and variants with 10, “Selection filter,” and 10. Do not turn the figure into a dose. Keep Mutation and variants with “Selection filter” and 10 from 10. 1010

Interactive Scenario & Decision Matrix
Select your current objective to inspect the recommended benchmark, threshold, and verification path.
The encounter to keep is {route0}.
Briefing 11 for Antibiotic resistance aligns condition “Selection, not spite” with reference value 1945 on the ground.
Antibiotic resistance: 1945 (2026)Keep this fact beside the route: {fact0}.
Reading 12 of Antibiotic resistance uses “Borrowed genes” and figure 1945 as a checkable baseline.
Antibiotic resistance: 1945 (2026)Say {route0}, then {fact0}. That is the one-line scale.
Atlas note 13 on Antibiotic resistance defines the operating range of 1945 when “Hospital pressure” applies.
Antibiotic resistance: 1945 (2026)Reading 4 of Antibiotic resistance uses “Farm pressure” and figure 1945 as a checkable baseline.
Dossier 14 for Antibiotic resistance links case “Farm pressure” directly to metric 1945 (2026).

5-Step Execution & Verification Playbook
- Name the encounter route — In the encounter-route picker, read the first listed route: {route0}. It is a public-health interface already on this page — pick it to reopen later.
- Read one quick fact as scale literacy — From quick facts, treat {fact0} as classroom context. It teaches scale and history, not your personal test result.
- Use the log-scale slider as teaching — The nm slider on this atlas compares sizes in powers of ten. It is a teaching device on published marks, not a measurement of you.
- This is not a diagnosis — Nothing on {name} issues a care plan, prescription, or outbreak alert. Seek a clinician for personal medical advice.
- Antibiotic resistance (5) — Atlas note 45 on Antibiotic resistance defines the operating range of 1945 when “Selection, not spite” applies.
Myth vs. Evidence Fact-Check
Is influenza a virus or a bacterium?
Influenza viruses are Orthomyxoviridae. Types A and B drive most human seasonal disease; A also has animal reservoirs. This page is an encounter atlas — not a lab result or a diagnosis.
How soon after exposure do flu symptoms start?
Symptoms often start about 1–4 days after exposure. People can shed virus before they feel ill. Teaching fact only — not a personal care plan.
Which encounter routes are already listed on this influenza page?
Six public-health encounters already written here: seasonal wave (community), hospital pneumonia (risk), workplace spread (everyday), vaccine offer (prevention), travel mixing (ecology), and antiviral stewardship (clinic). Pick one to reopen later. Classroom literacy — not an outbreak alert.
Which influenza A subtypes have circulated in people in recent decades?
Seasonal A viruses in people have been mainly H1N1 and H3N2, plus influenza B lineages. WHO-linked meetings pick Northern Hemisphere vaccine strains in February and Southern ones in September.
