Normally, the Classic period in Mesoamerica is characterized as the stage in which the arts, science, urbanism, architecture, and social organization reached their peak. This period was also dominated by the influence of Teotihuacan throughout the region, and the competition between the different Mesoamerican states led to continuous warfare.
The most common name for the killer virus, the Spanish flu, implied, of course, that it originated in Spain. Perhaps this was because there were serious outbreaks in both Madrid and Seville that infected eight million people in May of 1918 alone, even almost taking out the king himself, Alfonso XIII.
Since most people first heard about the flu from its attack on Spain, the new flu was named the Spanish flu. The Spanish flu then spread to Russia, India, China, and Africa. By the end of July 1918, after having infected people all around the world, this first wave of the Spanish flu appeared to be dying out. The Spanish Flu Becomes Incredibly Deadly.

In late August 1918, the second wave of the Spanish flu struck three port cities at nearly the same time.
