The Aztecs, a once-flourishing civilization in central Mexico, faced a devastating onslaught in the mid-16th century. While initially attributed to European diseases like smallpox, recent DNA analysis sheds new light on the mysterious illness that nearly obliterated them. Living amidst a cultural tapestry of nobility and commoners, the Aztecs thrived until the arrival of Spanish conquistadors, heralding a cascade of calamities.
Between 1545 and 1550, the Aztecs were besieged by a deadly outbreak of disease known as cocoliztli, claiming millions of lives in a matter of days. Characterized by fever and profuse bleeding, the epidemic left an indelible mark on Aztec history. Researchers identified a strain of salmonella, Paratyphi C, as a probable culprit, potentially introduced by European colonizers.
The devastation was compounded by climatic upheavals, with a prolonged drought exacerbating the death toll. Human sacrifice, a ritualistic practice, further depleted their ranks. Francisco Hernandez’s detailed accounts depict a myriad of symptoms, yet no single disease aligns precisely with his descriptions.
