Introduction:
The COVID-19 pandemic has affected several neglected populations such as the Indigenous peoples, which have suffered a high impact from the pandemic.
Objectives:
To analyze the impact on the health and disease process according to the COVID-19 evolution in the Brazilian Indigenous population.
Methods:
Data was collected from press releases by the Health Ministry and a descriptive analysis of the numbers of Indigenous individuals infected with the SARS-CoV-2 in Brazil was carried out.
Results:
In February 2021, there were 41,855 confirmed cases of Indigenous individuals infected by the SARS-CoV-2, including 4,387 active cases, 36,809 recovered cases, and 549 deaths. The Brazilian Indigenous population is distributed in over 300 ethnic groups and, due to the high number of deaths by the COVID-19, many of these groups are endangered. The elderly are the most affected age group, and they play a fundamental role among the Indigenous population for transmitting their customs mainly orally. Indigenous populations do not have proper access to transport to specialized health centers, since many areas are inaccessible and other cases require air or river transportation, which many times results in late assistance. When managing the COVID-19, it is important to emphasize the need for social isolation to prevent the virus from spreading among the Indigenous groups, mainly due to their contact with other ethnic groups represented by missionaries, hunters, and wood explorers, among others.
Conclusion:
The adoption of practices that can reduce the virus transmission among the Indigenous population and provide them with better access to treatment, mainly for the elderly, must be prioritized in Brazil.
