The new coronavirus in humans has unleashed a pandemic in the world, due to its easy transmission and the intense flow of people and transport. The state of Bahia, with its 417 municipalities and almost 15 million inhabitants, had its first case registered on 03/06/2020. The local health authorities are in action, looking for solutions to stop the progress of COVID-19, minimize the impact on the population and provide precious time to better adapt the health system. In this perspective, the understanding of the movement of people and the transport system in the state is very important to guide decision making. This note takes into account the Strategic Intelligence Analysis for the purposes of strategic advice in the decision-making process, in this case, aiming to subsidize health authorities in the state of Bahia, at the state and municipal levels. Based on spatial elements of the transport system and data from cities with confirmed cases of COVID-19, Geomathematics associated with GIS was used, through analysis tools, which identified on 04/02/2020, 304 municipalities at risk high or very high for the occurrence of new cases of COVID-19.
