The risk of malaria infection for travelers visiting the Brazilian Amazonian region: A mathematical modeling approach.

Background: Human mobility between malaria endemic and malaria-free areas can hinder control and elimination efforts in the Amazon basin, maintaining Plasmodium circulation and introduction to new areas.

Methods: The analysis begins by estimating the incidence of malaria in areas of interest. Then, the risk of infection as a function of the duration of stay after t was calculated as the number of infected travelers over the number of arrived travelers.
