abstract = "Background This study aims to describe the role of mobility in
malaria transmission by discussing recent changes in population
movements in the Brazilian Amazon and developing a flow map of
disease transmission in this region. Methodology/Principal
findings This study presents a descriptive analysis using an
ecological approach on regional and local scales. The study
location was the municipality of Porto Velho, which is the capital
of Rond{\^o}nia state, Brazil. Our dataset was obtained from the
official health database, the population census and an
environmental database. During 2000-2007 and 2007-2010, the Porto
Velho municipality had an annual population growth of 1.42% and
5.07%, respectively. This population growth can be attributed to
migration, which was driven by the construction of the Madeira
River hydroelectric complex. From 2010 to 2012, 63,899
malariapositive slides were reported for residents of Porto Velho
municipality; 92% of the identified samples were autochthonous,
and 8% were allochthonous. The flow map of patients' movements
between residential areas and areas of suspected infection showed
two patterns of malaria transmission: 1) commuting between
residential areas and the Jirau hydropower dam reservoir, and 2)
movements between urban areas and farms and resorts in rural
areas. It was also observed that areas with greater occurrences of
malaria were characterized by a low rate of deforestation.
Conclusions The Porto Velho municipality exhibits high malaria
endemicity and plays an important role in disseminating the
parasite to other municipalities in the Amazon and even to
non-endemic areas of the country. Migration remains an important
factor for the occurrence of malaria. However, due to recent
changes in human occupation of the Brazilian Amazon, characterized
by intense expansion of transportation networks, commuting has
also become an important factor in malaria transmission. The
magnitude of this change necessitates a new model to explain
malaria transmission in the Brazilian Amazon.",
