The occurrence of rabies in pre-Columbian Central America: an historical search
Abstract:
Rabies is considered one of the oldest infectious diseases known to humans. However, the first written reports on rabies cases in the Americas did not appear until the first decade of the 18th century from Mexico. In an attempt to clarify if the disease was already present in pre-Columbian times, we searched for evidence in the Maya and Aztec cultures. Other sources of information were early manuscripts written by the conquistadors and early explorers. We did not identify any unequivocal direct evidence that the disease rabies was known in pre-Columbian Central America but sufficient circumstantial evidence is available suggesting that (bat) rabies was already present in these early times.
Insights
This study investigated pre-Columbian rabies in the Americas. While direct evidence is lacking, circumstantial findings suggest bat rabies existed before European arrival.
Area of Science:
- * Paleovirology and Historical Epidemiology
- * Investigating ancient infectious diseases in Central America
Background:
- * Rabies is an ancient zoonotic disease with a long history in humans.
- * The earliest documented rabies cases in the Americas date to the 18th century in Mexico.
Observation:
- * Searched for evidence of rabies in Maya and Aztec cultures.
- * Examined manuscripts from conquistadors and early explorers for disease descriptions.
Findings:
- * No definitive direct evidence confirms rabies knowledge in pre-Columbian Central America.
- * Circumstantial evidence strongly suggests the presence of bat-borne rabies during this period.
Implications:
- * Understanding the historical presence of rabies in the Americas.
- * Informing future research on zoonotic disease emergence in ancient populations.
