How come there were cases of the Spanish flu after it subsided in the summer of 1919? How can that work?

    Viruses, especially coronaviruses, mutate in order to survive, some of those mutations are harmless, some are not.

    It was a seasonal phenomena like colds or other flus. The virus never fully disappeared; it just didn't do well in sunlight or higher temperatures.

    There were cases of Spanish Flu until at least the 50s.

    Viruses don't just "disappear" without an actual eradication campaign.  And nothing remotely like that was even possible a century ago.
