“…The case fatality rate of COVID-19 was 2.05 and 2.19 per 100,000 people for the indigenous and non-indigenous populations, respectively. Previous data have shown the worst disease lethality in indigenous people 3,25,26 , though this may have changed due to the decrease in the number of cases and deaths after vaccination. In addition, our assessment covered indigenous peoples from remote and urban areas, failing to differentiate indicators related to spatial localization.…”

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 nonindigenous 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.

“…Se ha informado de que la COVID-19 está azotando gravemente las aldeas indígenas rurales ubicadas en las reservas ( 14 ), pero no hay comparaciones con otros grupos étnicos. Como se señaló en la introducción, Baqui et al encontraron que en Brasil la mortalidad hospitalaria por COVID-19 era mayor en las personas con ascendencia negra o mixta que en las blancas ( 5 ).…”

Objetivos. Investigar las desigualdades socioeconómicas y entre distintos grupos étnicos en la prevalencia de anticuerpos contra el SARS-CoV-2 en las 27 unidades federativas de Brasil. Métodos. En este estudio transversal, se realizaron tres encuestas de hogares los días 14-21 de mayo, 4-7 de junio y 21-24 de junio de 2020 en 133 áreas urbanas brasileñas. Se utilizó un muestreo de etapas múltiples para seleccionar 250 individuos en cada ciudad a fin de someterlos a una prueba rápida de anticuerpos. Los sujetos respondieron un cuestionario sobre los bienes del hogar, la escolaridad y el color de la piel y etnia (autodeclarado utilizando la clasificación brasileña estándar de cinco categorías: blanco, negro, pardo, asiático o indígena). Se utilizó el análisis de los componentes principales de los bienes para clasificar el estatus socioeconómico en cinco quintiles de riqueza. Se empleó la regresión de Poisson para los análisis. Resultados. Se analizaron 25 025 sujetos en la primera encuesta, 31 165 en la segunda y 33 207 en la tercera, que mostraron una prevalencia de resultados positivos de 1,4%, 2,4% y 2,9%; respectivamente. Los individuos del quintil más pobre tuvieron 2,16 veces más probabilidades de presentar un resultado positivo (intervalo de confianza del 95%: 1,86-2,51) que los del quintil más rico, y los que tenían 12 o más años de escolaridad tuvieron una prevalencia menor que los sujetos con menos educación. Las personas indígenas presentaron una prevalencia 4,71 (IC95%: 3,65-6,08) veces mayor que las blancas, al igual que las de piel negra o parda. El ajuste por región del país redujo los índices de prevalencia según la riqueza, la educación y el origen étnico, pero los resultados siguieron siendo estadísticamente significativos. Conclusiones. La prevalencia de anticuerpos contra el SARS-CoV-2 en Brasil muestra gradientes relacionados con la posición socioeconómica y la etnia muy pronunciados, con menor riesgo en las personas blancas, educadas y ricas.

“…Hence, this critical finding needs more analysis in future studies. To the best of our knowledge, this is one of the first reports about Amerindian ethnicity as a risk factor for death in patients with COVID-19 in Latin America [ 3 , 25 ].…”

Ethnicity and other COVID-19 death risk factors in Mexico

et al. 2020

IntroductionPatients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may develop coronavirus disease 2019 (COVID-19). Risk factors associated with death vary among countries with different ethnic backgrounds. We aimed to describe the factors associated with death in Mexicans with confirmed COVID-19.Material and methodsWe analysed the Mexican Ministry of Health’s official database on people tested for SARS-CoV-2 infection by real-time reverse transcriptase–polymerase chain reaction (rtRT-PCR) of nasopharyngeal fluids. Bivariate analyses were performed to select characteristics potentially associated with death, to integrate a Cox-proportional hazards model.ResultsAs of May 18, 2020, a total of 177,133 persons (90,586 men and 86,551 women) in Mexico received rtRT-PCR testing for SARS-CoV-2. There were 5332 deaths among the 51,633 rtRT-PCR-confirmed cases (10.33%, 95% CI: 10.07–10.59%). The median time (interquartile range, IQR) from symptoms onset to death was nine days (5–13 days), and from hospital admission to death 4 days (2–8 days). The analysis by age groups revealed that the significant risk of death started gradually at the age of 40 years. Independent death risk factors were obesity, hypertension, male sex, indigenous ethnicity, diabetes, chronic kidney disease, immunosuppression, chronic obstructive pulmonary disease, age > 40 years, and the need for invasive mechanical ventilation (IMV). Only 1959 (3.8%) cases received IVM, of whom 1893 were admitted to the intensive care unit (96.6% of those who received IMV).ConclusionsIn Mexico, highly prevalent chronic diseases are risk factors for death among persons with COVID-19. Indigenous ethnicity is a poorly studied factor that needs more investigation.
