Clinical and spatial characteristics of Severe Acute Respiratory Syndrome by COVID-19 in Indigenous of Brazil

Abstract

The indigenous people of Brazil present several cases and deaths, affecting 158 peoples, with high vulnerability and limited access to health services. The objective is to investigate the clinical characteristics of severe acute respiratory syndrome by COVID-19 in indigenous peoples of Brazil. The epidemiological study, descriptive, from the data of the platform opendataSUS referring to the SIVEP-GRIPE in the period 01/01/2020 until 31/08/2020. Profile variables, signs and symptoms, and risk/comorbidities factors. The data were analyzed by Bioestat 5.3. 1,207 cases and 470 deaths. Profile: male gender (59.48%) mean age 53. Signs and symptoms: fever (74.23%), cough (77.71%), sore throat (35.62%), dyspnea (69.34%), respiratory discomfort (62.80%), O2 saturation <95% (56.42%); and associated with mortality: dyspnea (80.0%) and O2 saturation <95% (69.36%). Risk factors and comorbidities (45.89%) were associated with deaths (54.04%). Comorbidities: Chronic Cardiovascular Disease (18.97%) and Diabetes Mellitus (18.97%), and associated with deaths: Chronic Cardiovascular Disease (24.46%). There was significance in the survivors vaccinated for influenza (26.18%). The public and health policies of Brazil should be directed to control the dissemination of COVID-19 in this population, that COVID-19 evolves in the same intensity, however, the indigenous have vulnerabilities that can enhance the impact of the pandemic in this population.

Epidemiological analysis of hospitalized cases of COVID-19 in in-digenous people in an Amazonian region: cross-sectional study with data from the surveillance of acute and severe respiratory syn-dromes in Brazil

“…Being corroborated by the study (Sardinha, Lima, et al, 2021) which identified chronic heart diseases (18.97%) and diabetes (18.97%) among the most prevalent comorbidities in the indigenous population with SARS due to COVID-19.…”

“…These results corroborate the literature. (Sardinha et al, 2020) also report greater survival by SRAG among those vaccinated against influenza in Brazil.…”

“…Similarly, in a study conducted in Brazil with 472,688 severe cases, the independence test was highly significant in vaccinated survivors (<0.0001), and the binary regression showed an odds ratio almost twice as high for invasive ventilation, admission to the hospital. ICU and death in unvaccinated cases (Sardinha, Lobato, et al, 2021).…”

“…A study regarding the characteristics of SARS by COVID-19 in indigenous people in Brazil also identified that being hospitalized in the ICU is a predictor of risk of death, with a chance of 3.96 (OR 3.960: CI 2.913-5,383: <0.0001) (Sardinha, Lima, et al, 2021).…”

Medical Imaging and its Role in Detection of COVID-19

“…Typical changes in chest High Resolution Computed Tomography of COVID-19 patient: Peripheral, bilateral, Ground Glass Opacification with or without consolidation or visible interlobular lines ("web like" or "crazy paving") Multifocal Ground Glass Opacification of rounded morphology with or without consolidation or visible intralobular lines ("web like" or "crazy paving") Reverse halo sign or other findings of organizing pneumonia [28] [29]. V. CONCLUSION In this paper, we presented the functioning and viable applications of medical imaging.…”
