Abstract:The Brazilian Northern region registered a high incidence of COVID-19 cases, particularly in the state of Pará. The present study investigated the risk factors associated with the severity of COVID-19 in a Brazilian Amazon region of 100,819 cases. An epidemiological, cross-sectional, analytical and demographic study, analyzing data on confirmed cases for COVID-19 available at the Brazilian Ministry of Health's surveillance platform, was conducted. Variables such as, municipalities of residence, age, gender, si… Show more
“…A study in the same region of the Amazon analyzed the risk factors for severity of COVID-19, but included all cases, mild, moderate and severe, totaling 100,819 being the largest epidemiological study of COVID-19 conducted in the region in the period from March 1 to July 29, 2020. Regarding the risk of death from cardiovascular disease, the study showed in the logistic regression model (OR 4.090—CI 3.759–4.450) a four times greater chance of death in patients with CVD 25 .…”

The northern region of Brazil is already vulnerable to other infectious diseases and it was no different in COVID-19. However, cardiovascular diseases still lead the causes of death. Thus, the objective of this study is to identify the clinical predictors and outcome of severe COVID-19 in hospitalized patients with and without CVD in this region of the Amazon. A retrospective cohort, referring to the notifications from January 1 to December 31, 2020, including cases confirmed by molecular testing. The study consisted of 9223 confirmed cases for COVID-19. Of these, 6011 (65.17%) did not have cardiovascular disease and 3212 (34.83%) had some cardiovascular disease. The significance of deaths was in the age group of < 1 to 59 CVD carriers (< 0.001). Predictor of mortality were invasive ventilation for patients with CVD, (OR 23,688 CI 18,180–30,866), followed by chronic kidney disease (OR 2442 CI 1568–3740), dyspnea (OR 2312 CI 1817–3941), respiratory distress (OR 1523 CI 1210–2919), cough (OR 1268 CI 1005–1599), Lower oxygen saturation 95% (OR 1281 CI 1039–1579), diabetes mellitus (OR 1267 CI 1050–1528) and age (OR 1051 CI 1044–1058). Carriers of CVD had a lower survival rate (< 0.0001). The order of the predictors of death differed among the non-carriers, as well as the high odds ratio in the predictors of CVD, only cough was an independent predictor. The age group under 59 years was associated with deaths. We also show the shorter survival in CVD carriers, as well as the higher cardiovascular morbidity rate than other studies in the literature.

“… In pandemics, people in different socio-cultural groups may adopt self-protective behaviors including vaccination and respond to government policies in distinct ways. In Peru, increased vulnerability of Indigenous people is a major concern as found also in Brazil 52 . …”
Understanding COVID-19 contagion among poor populations is hampered by a paucity of data, and especially so in remote rural communities with limited access to transportation, communication, and health services. We report on the first study on COVID-19 contagion across rural communities without road access. We conducted telephone surveys with over 400 riverine communities in the Peruvian Amazon in the early phase of the pandemic. During the first wave (April–June, 2020), COVID-19 spread from cities to most communities through public and private river transportation according to their remoteness. The initial spread was delayed by transportation restrictions but at the same time was driven in unintended ways by government social assistance. During the second wave (August, 2020), although people’s self-protective behaviors (promoted through communication access) helped to suppress the contagion, people responded to transportation restrictions and social assistance in distinct ways, leading to greater contagion among Indigenous communities than mestizo communities. As such, the spatial contagion during the early phase of the pandemic in tropical forests was shaped by river transportation and social behaviors. These novel findings have important implications for research and policies on pandemics in rural areas.

The surveillance of live births in Brazil has been carried out since 1990 by the Information System on Live Births (SINASC), which was implemented by the Ministry of Health aiming at standardized registration on a national level. The state of Para is part of the Brazilian Amazon, northern Brazil, which has several unique characteristics. Thus, the purpose of this study was to identify the epidemiological pattern of live births before and during the pandemic of COVID-19 in the state of Para, 2016 to 2020. This is an ecological epidemiological time-series study, using epidemiological surveillance data from DATASUS, referring to the Live Births Information System (SINASC). These are data that have been treated by surveillance and are in aggregate format. The study population is the live births residing in the state of Para, in the period from 2016 to 2020. The data collection instrument was the Declaration of Live Births (DLB). There were 689,454 live births, and the highest rates of births were and continued to remain in the Marajo II, Baixo Amazonas, Xingu, and Tapajos regions. The Metropolitan I and Araguaia regions were and continue to be the lowest rates in the state. Age of the mother 15 to 19 years old 22.29%, 20 to 24 years old 30.05% and 25 to 29 years old 22.58%, most of the single pregnancy type 98.32%, prenatal consultations, performed 7 or more 48.10%, followed by 4 to 6 consultations 33.98%, most presented 7 or more years of the study 48.10%, followed by 3 to 6 years 33.98%. Represented 51.21% male and 48.77% female. The occurrence of congenital anomalies represented 0.52% of live births. Another congenital malformation and deformity were the most prevalent at 25.53%, followed by Congenital deformities of the feet 14.90%, Other congenital malformations of the nervous system 14.84%, and Other congenital malformations 10.77%, Cleft lip, and cleft palate 8.88%, Other congenital malformations digestive tract 8.10%. The demographic transition has already occurred for several decades, including the reduction of fertility and birth rate, so our study showed that the reduction in the number of live births was already a reality in the country, but we emphasize that this reduction was enhanced by the pandemic. We observed greater adherence to prenatal care and a lower prevalence of low birth weight compared to other studies, but the limitation was the absence of studies in the same place of the research. Regarding data incompleteness, we emphasize the ignored fields that reflect the fragility in the surveillance of live births, which was reinforced by the literature.
