COVID-19 outbreaks in endangered Indigenous groups from the Amazonia during the first wave of the COVID-19 pandemic in Ecuador: a retrospective cross-sectional study.
Introduction: The COVID-19 pandemic has deeply affected Latin American countries, with countless COVID-19 cases and deaths. In countries like Mexico, Brazil, Peru, Colombia and Ecuador, the public health system collapsed and the lack of testing capacity did not allow control of the spread of SARS-CoV-2 during the first year of the COVID-19 pandemic. Moreover, rural and Indigenous communities in these countries, particularly isolated ones like those in the Amazon Basin, were neglected in terms of access to COVID-19 testing and medical aid.
Methods: In this study, we retrospectively analyzed the impact of COVID-19 outbreaks among several endangered Amazonian ethnic groups during the first wave of the COVID-19 pandemic in Ecuador. From June to August 2020, 21 Amazonian communities were included in a COVID-19 surveillance led by Indigenous community leaders and non-profit organizations.
Results: A total of 853 individuals were tested for SARS-CoV-2 infection by RT-qPCR. A high SARS-CoV-2 infection rate of 54.05% (461 positive individuals) was found. Only one community was COVID-19 free, and the other 20 communities had severe COVID-19 outbreaks with infection rates up to 90%. For the different ethnic groups, the infection rates were 46.0% for Waoranis, 66.15% for Sionas, 49.8% for Kichwas, 54.9% for Kofans and 62.3% for Shuars. Additionally, 29 individuals had SARS-CoV-2 viral load values higher than 108 copies/mL.
Conclusion: Our findings confirm that Indigenous communities of Ecuadorian Amazonia were exposed to SARS-CoV-2 community transmission since the early stages of the COVID-19 pandemic, with the potential occurrence of superspreading events. As the COVID-19 national surveillance program was focussed on symptomatic individuals attending hospital facilities, rural and remote Indigenous communities in the Ecuadorian Amazonia, including endangered ethnic minorities, were neglected during the first wave of the COVID-19 pandemic.
期刊介绍：
Rural and Remote Health is a not-for-profit, online-only, peer-reviewed academic publication. It aims to further rural and remote health education, research and practice. The primary purpose of the Journal is to publish and so provide an international knowledge-base of peer-reviewed material from rural health practitioners (medical, nursing and allied health professionals and health workers), educators, researchers and policy makers.
