Correct. However, the virus quickly mutated. There was no one variant since it changed quickly. Comparing samples from multiple locations allows identification and tracking of the changes.
FWIW, one of my grandmothers died from the Spanish Flu in 1920.
The Spanish Flu killed quickly: sometimes people who appeared perfectly healthy in the morning were dead by late afternoon. Many of my family died from it, leaving orphans who were just taken in and raised by the survivors. The doctor came to see my father who had it as a child. My grandfather was angry when the doctor never returned, and when asked about it later, he said that he just assumed my father had died soon after the visit.
