Mercury is classically known as the major source of environmental pollution in the Amazonian region, a fact closely related to its wide use in illegal gold mining activity and other anthropogenic interventions such as dams and fires [, Another important factor contributing to the increase in mercury emissions is the extensive biomass burning and deforestation, which are very recurrent in the Brazilian Amazon (, Considering that the first case of COVID-19 registered in Brazil was on 25 February 2020 [, The high SARS-CoV-2 transmissibility was generally observed in the North of Brazil, which presented a higher rate than other Brazilian regions, particularly in the South, as reported by the Oswaldo Cruz Foundation (Fundao Oswaldo Cruz in Portuguese, also known as FIOCRUZ) (, In addition to the high incidence of SARS-CoV-2 infection, Amazonian populations experience a high exposure to mercury [, Unfortunately, Brazil is currently facing a humanitarian crisis: hundreds of adults and children of Yanomami indigenous communities are dying due to starvation, undernutrition, infectious diseases and mercury poisoning (, Furthermore, Amazonian populations face several challenges, particularly regarding healthcare; the scenario is even worse considering the traditional Amazonian populations, [, All the features mentioned previously put Amazonian populations in a vulnerable situation [, From the point of view of public health, the Amazon has additional factors that make it the most important case study to be carried out to better understand the dynamic of the relationship of COVID-19 and mercury intoxication.
