Why doesn’t the poliovirus evolve as rapidly as the flu virus does?
Part of the reason that flu can be really dangerous is that it infects so many species. Swine, birds, humans etc. Not every strain can infect every animal.
The Short Answer
Part of the reason that flu can be really dangerous is that it infects so many species. Swine, birds, humans etc. Not every strain can infect every animal. But some animals can be infected with many types of strains, and when infected with more than one type at a time they act as a mixing basin, allowing new combinations of flu parts.
