Abstract

Objectives

This cross-sectional study presents socioecological, epidemiological aspects, and the seroprevalence of immunoglobulin G (IgG) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a group of quilombola (afro-derived) communities in the states of Pará and Tocantins, in the Brazilian Amazon, to evaluate the impact of SARS-CoV-2 prevalence among them.

Methods

A total of 551 individuals participated. The detection of anti-SARS-CoV-2 antibodies was performed using an enzyme immunoassay. Socioeconomic and ecological data was collected from all participants 7 years of age or older who were not previously vaccinated.

Results

The seroprevalence of antibodies in both states was 40.7% and was associated with factors such as age group, contact with infected individuals, and being in lockdown inside the quilombos. In Pará, a statistically significant association was observed between seroprevalence and females, and the age group of 12–18 years. In addition, seroprevalence in Pará was higher than in Tocantins, and the reported use of masks was a protective factor, while in Tocantins, the reported use of masks was associated with the presence of antibodies. There was no association between the prevalence of antibodies and the presence of COVID-19 symptoms in Pará. However, in Tocantins, diarrhea and loss of taste were associated with infection.

Conclusions

Quilombola are highly vulnerable groups due to the long history of enslavement in Brazil. This is the first investigation of SARS-CoV-2 seroprevalence and its impact in these groups in the Amazon. The study helps us to understand the relationship of socioecological differences, behavioral characteristics, and the dynamics of viral transmission associated with the risk of infection by SARS-CoV-2 among traditional populations, and can be useful to the planning of more culturally adequate public health policies for future epidemics.

生活在巴西亚马逊地区的Quilombolas的SARS-CoV-2感染的社会生态和流行率Socioecologia e Prevalencia de Infeccao pelo SARS-CoV-2 em Quilombolas Vivendo na Brasileira

本横断面研究介绍了巴西亚马逊地区par州和托坎廷斯州一组非裔社区中针对严重急性呼吸综合征冠状病毒2 （SARS-CoV-2）的社会生态学、流行病学和免疫球蛋白G （IgG）的血清阳性率，以评估SARS-CoV-2流行对他们的影响。方法551人参与调查。采用酶免疫分析法检测抗sars - cov -2抗体。收集了所有7岁或以上以前未接种疫苗的参与者的社会经济和生态数据。结果两州血清抗体阳性率均为40.7%，与年龄组、与感染者接触、在“歌伦波”内被隔离等因素有关。在par中，血清阳性率与女性和12-18岁年龄组之间有统计学意义的关联。此外，par的血清阳性率高于Tocantins，报告使用口罩是一个保护因素，而在Tocantins中，报告使用口罩与抗体的存在有关。par中抗体的流行与COVID-19症状的存在之间没有关联。然而，在Tocantins中，腹泻和味觉丧失与感染有关。结论由于巴西长期的奴役历史，“歌隆波拉”是非常脆弱的群体。这是对亚马逊地区这些人群中SARS-CoV-2血清阳性率及其影响的首次调查。该研究有助于我们了解传统人群中与SARS-CoV-2感染风险相关的社会生态差异、行为特征和病毒传播动态之间的关系，并有助于为未来的流行病制定更具文化适应性的公共卫生政策。

期刊介绍： The American Journal of Human Biology is the Official Journal of the Human Biology Association. The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field. The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology. Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification. The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
