The rat population was depleted during the drought, when food was scarce. But once the rains returned, food and water were suddenly plentiful and the number of infected rats exploded, spreading the deadly scourge to humans. As weather swings become more erratic and the southwest bakes under increasingly prolonged droughts, epidemics like cocolitzli will doubtless return. Sooner or later, a new virus will emerge from the desert for which we dont have any vaccine and we cant treat with drugs, said Acuna-soto. Thats the big fear of science. The only thing we dont know is when.

This sounded like a hemorrhagic fever. So if the Spanish didnt bring about the fever, what did? In his research, Acuna-soto had noticed a pattern: the plague was listing preceded by years of severe drought but the epidemics occurred only during wet weather, and heavy rainfall. To confirm his observations, Acuna-soto worked with a mexican-American team of dendrochronologists—scientists who study tree rings to date changes in climate—and compared the 16th century historical accounts with tree-ring records from a forest of 450-year-old douglas fir trees in a remote region of central Mexico. The tree rings indicated that the most severe and sustained drought in North America in the past 500 years occurred in the mid-16th century. But there were heavy downpours in the years around 15, which coincided with the cocolitzli outbreaks. The smoking gun was the tree ring data, acuna-soto said. Acuna-soto is now convinced that the death knell for the aztecs was an indigenous hemorrhagic fever virus spread by rodents, not the Spanish conquest.
In particular, they detailed the plagues of cocoliztli (Nahuati for pest a disease that seemed far more virulent than smallpox. The aztecs mysterious plague, nobody had the health or strength to help the diseased or bury the dead, one Franciscan friar wrote in 1577 about the devastation from cocolitzli. In the cities and large towns, big ditches were dug, and from morning to sunset the priests did nothing else but carry the dead bodies and throw them into the ditches. Acuna-soto ali also had access to exhaustive diaries kept by Francisco hernandez, the surgeon general of New Spain who witnessed the second catastrophic epidemic in 1576. He described a highly contagious and lethal scourge that killed within a few days, causing raging fevers, jaundice, tremors, dysentery, abdominal and chest pains, enormous thirst, delirium and seizures. Blood flowed from the ears, the physician observed, and in many cases blood truly gushed from the nose. These symptoms didnt sound like smallpox or any other known European disease that was in Mexico during the 16th century, acuna-soto told.
type of weather pattern may be what led to the fall of the once mighty aztec Empire in the early 16th centuryand not as is commonly held, by the invasion of European colonialists, who brought with them diseases like mumps, measles and smallpox. Curious timing, when Hernando cortes and his army conquered Mexico starting in 1519, there were roughly about 25 million people living in what is now Mexico. A hundred years later, after a series of epidemics decimated the local population, perhaps as few.2 million natives survived. Records confirm there was a smallpox epidemic in 15, immediately after the europeans arrived, killing between 5 and 8 million people. But it was two cataclysmic epidemics that occurred in 15, 25 and 55 years after the Spanish conquest, which swept through the mexican highlands and claimed as many as 17 million lives. Rodolfo Acuna-soto, a harvard-trained infectious disease specialist at the national Autonomous University of Mexico in Mexico city, it made no sense that a deadly outbreak of European origin could occur so long after the Spanish arrived, because the natives who survived previous plagues would have. To find answers, Acuna-soto spent a dozen year poring through ancient documents written by 16th century Spanish priests who worked with the aztecs to preserve a record of their history, language and culture. These texts also tracked key natural events—storms, droughts, frosts and illness.
