AI ranks our best-known RNA viruses by speed of mutation.
HIV: Highest mutation rate (~1–10 × 10⁻⁵ substitutions per site per replication cycle), driven by its error-prone reverse transcriptase. Influenza (Flu): ~1–8 × 10⁻³ substitutions per site per year, with rapid evolution due to antigenic drift and segmented genome. COVID-19 (SARS-CoV-2): ~1–2 × 10⁻³ substitutions per site per year, moderate among RNA viruses. RSV (Respiratory Syncytial Virus): ~1–2 × 10⁻³ substitutions per site per year, similar to COVID-19 but slightly variable in key genes. Measles: Lowest mutation rate (~0.6–1 × 10⁻³ substitutions per site per year), highly stable for an RNA virus.This ranking reflects the relative mutation rates, with HIV mutating fastest and measles the slowest. Note that direct comparisons can be nuanced due to differences in replication cycles and genome sizes.
Remember:
RSV is fast enough for its vaxx products to make no sense & not work......... ............ topic here
same or worse ⬆ for flu & covid..... ........... yet those products are pushed on people?? It protects Big Pharma finances.
