Tsimané and Moseten peoples of lowland Bolivia demonstrate an intriguing case of epidemiological resilience
Despite widespread COVID-19 infection in the Tsimané and Moseten populations of Bolivia, the mortality rate in these remote Indigenous groups was the lowest ever recorded for any population or region.
The Tsimané and Moseten peoples of lowland Bolivia have exhibited a remarkable ability to resist the impacts of the COVID-19 pandemic, defying expectations given their lack of access to healthcare. Despite widespread infection, their mortality rate was the lowest ever recorded for any population. Research suggests that their resilience may stem from a more vigorous immune response to infection and an upregulated immune system due to persistent exposure to pathogens.
With high levels of COVID-specific antibodies and infection-fighting white blood cells, the Tsimané and Moseten may have been able to contain the virus before it progressed to more severe stages. The combination of their nonindustrial lifestyle, active physical activity, and exposure to diverse pathogens likely contributes to their enhanced immune readiness.
This unique combination of factors could serve as a valuable insight for global pandemic preparedness.
