The Covid-19 pandemic and regional particularities of its diffusion in the urban network segment in the state of Tocantins, Brazil.

This paper presents contributions on the spatial diffusion of Covid-19 in the state of Tocantins, considering the spatial interactions of the main regional, sub-regional and micro-regional centers, as well as the regional particularities of this urban network. It was pointed out a complex geographical position in the North Center region of Brazil, with spatial articulations among regions, locations, cities and people, which facilitate the spread of the pandemic, not only through hierarchical interactions, but also through complementary interactions. Such interactions reveal two dispersion patterns, a vertical one and a horizontal one, which resulted in spatial configurations that combine nodes, axes and areas, which place Tocantins in a critical epidemiological situation.
