Resumen:	This cross-sectional observational study that describes the epidemiological data of the first year of the COVID-19 pandemic in the Mato Grosso do Sul State, aimed to demonstrate the differences between indigenous and non-indigenous populations, characterize confirmed cases of COVID-19 according to risk factors related to ethnicity, comorbidities and their evolution and to verify the challenges in facing the disease in Brazil. SIVEP-Gripe and E-SUS-VE, a nationwide surveillance database in Brazil, from March 2020 to March 2021 in Mato Grosso do Sul state, were used to compare survivors and non-survivors from indigenous and non-indigenous populations and the epidemiological incidence curves of these populations. A total of 176,478, including 5,299 indigenous people, were confirmed. Among the indigenous population, 52. 5% (confidence interval [CI] 51. 2-53. 9) were women, 38% (CI 36. 7-39. 4) were 20-39 years old, 56. 7% were diagnosed by rapid antibody tests, 12. 3% (CI 95%:11. 5-13. 2) had at least one comorbidity, and 5. 3% (CI 95%:4. 7-5. 9) were hospitalized. In the non-indigenous patients, 56. 8% were confirmed using RT-PCR, 4. 4% (CI 95%:4. 3-4. 5) had at least one comorbidity, and 8. 0% (CI 95%:7. 9-8. 2) were hospitalized. The majority of non-survivors were ≥60 years old (65. 1% indigenous vs. 74. 1% non-indigenous). The mortality in indigenous people was more than three times higher (11% vs. 2. 9%). Indigenous people had a lower proportion of RT-PCR diagnoses; deaths were more frequent in younger patients and were less likely to be admitted to hospital. Mass vaccination may have controlled the incidence and mortality associated with COVID-19 in this population during the period of increased viral circulation.
