DNA from Chilean Mummies Confirms Smallpox Was Brought from Europe
Andean Mummies Reveal Early Smallpox Arrival
Recent paleogenomic analysis of pre-Hispanic remains in South America confirms that European-introduced smallpox, caused by the variola virus, reached the Americas during early colonization, upending historical theories regarding the timing of the pathogen’s arrival and its lethal pathogenesis. According to research reported by outlets such as National Geographic España, Yahoo, and Xataka, DNA extracted from ancient mummies has definitively identified the viral presence in the region, offering tangible genetic proof of the epidemiological devastation that accompanied European contact.
- Genomic sequencing of historical Chilean mummies recovered from Chile confirms the early circulation of European variola virus strains in South America.
- The findings challenge prior clinical assumptions about the absolute lethality of early colonial smallpox strains, pointing toward potential evolutionary shifts in viral virulence over centuries.
Bridging Archaeological and Evidentiary Gaps
The investigation into the ancient South American mummies sheds new light on the epidemiological mechanisms that decimated indigenous populations following European colonization. The recent identification of variola virus genetic material bridges this evidentiary gap, allowing infectious disease experts to study the precise lineage and evolutionary trajectory of the pathogen.
Mapping Historical Viral Mutations
According to coverage by Deutsche Welle and The New York Times, analyzing these historical viral genomes reveals that smallpox strains circulating during early contact periods may have exhibited different morbidity and mortality profiles than their later, highly documented counterparts.
