The Spanish Flu, caused by the H1N1 influenza virus, did not need to mutate significantly as it spread because it was already highly contagious and capable of causing severe illness. The virus had a novel genetic makeup that was effective in infecting a large population, leading to widespread transmission. Additionally, the immune response in many individuals was not strong enough to prevent infection, allowing the virus to spread rapidly without requiring mutations to enhance its virulence or transmissibility.
