The maps presented here seek to offer an easy way to visualize the evolution of the cases of the new coronavirus among the populations residing in the municipalities where the demarcated indigenous lands are located, as well as in the municipalities where there are proposals for ethnic and cultural recognition. São Luís appears on the map because of its strategic administrative political position as the state capital and because it houses city-dwelling Indians from different indigenous peoples. The data that support the maps come from information published and available on the website of the Health Department of the State of Maranhão. They are updated periodically with the new data from the epidemiological bulletins of the State and municipalities of interest, in order to monitor the degree of vulnerability of the indigenous population to COVID-19.cr
