SOUSA, Jonata Ribeiro de et al. Malaria situation in the Lower Amazon Region, Pará State, Brazil, from 2009 to 2013: an epidemiological approach. Rev Pan-Amaz Saude [online]. 2015, vol.6, n.4, pp.39-47. ISSN 2176-6223.

The objective of the research was to understand the epidemiological features of malaria in the Lower Amazon Region, Pará State, Brazil. A retrospective and a statistical survey of the occurrence of health problems for Plasmodium species which cause malaria in the Lower Amazon Region were conducted from January 2009 to December 2013. The results show a constant presence of malaria in municipalities of that region, with 16,765 cases reported during the study period. The Municipalities with the highest number of cases were Oriximiná, Santarém, Alenquer and Prainha. The prevalence of infection was in males. There was a higher incidence from 20 to 29 years old, with 20.51% and from 30 to 39 years old with 14.96%. The age group 5-9 years old presented 12.47% of cases. The Plasmodium vivax was the most prevalent (76.84% of all cases) in all municipalities. The majority of municipalities were classified as areas of low risk of malaria transmission; the presence of detection forms of passive disease was found in 75.1% of cases and they were classified as autochthonous. Malaria cases were registered in pregnant women that only occurred in 2009, 2010 and 2011. It is notable the presence of malaria in the region, and it presents a great social, political and economic challenge, especially for its strong impacts on population health. Thus, the control measures should be maintained and involve necessarily all government segments.
