چکیده
INTRODUCTION In Tocantins, the behavior of malaria differs between microregions, with predominance of imported cases. This study describes a spatial analysis on malaria in the state covering 2003 to 2008, which sought to identify the incidence of autochthonous and imported cases, and the origin of the latter, in the microregions. METHODS This was a retrospective study using secondary data. The data source was the epidemiological surveillance information system for malaria (SIVEP-Malária), and the data were analyzed using the Epi Info version 3.5.1 and Bioestat version 5.0 statistical software. RESULTS It was found that malaria was not homogeneously distributed in all municipalities. The area of highest priority comprised municipalities located in microregions in the west of the state, at the border of Pará, which also had the highest number of autochthonous cases. The association between the autochthonous and imported cases and the Plasmodium species showed a statistically significant difference (G = 54.25; p < 0.0001). Among the eight microregions, Miracema do Tocantins, Araguaína and Bico do Papagaio accounted for 75.8% of the cases and, among these, eleven municipalities stood out. Regarding provenance, the State of Pará showed widespread distribution with 85.5% of the total, followed by French Guiana with 7.4%. CONCLUSIONS These results demonstrated the predominance of imported cases and the difference between municipalities and microregions, and showed the influence of neighboring states in determining the areas of greatest risk. These data are important, since they contribute towards guiding and directing public policies regarding this disease in Tocantins.

Malaria has been prevalent for a long time in Iran. About 1000 years ago, the Iranian physicians such as Avicenna (979-1037) were acquainted to the clinical feature of the disease. The scientific study of malaria in Iran was started by Latycheve in 1921. Later on up to 1944, malaria have been studied by some Iranian and foreign investigators and it was found hyper-endemic in some littoral parts...

Anopheles pulcherrimus Theobald has a wide distribution in western Asia and is a potential vector of malaria in Iran. We have examined the rDNA-ITS2 (internal transcribed spacer 2) region of An. pulcherrimus specimens collected during the two peaks of activity (May-June and October-November) from Sistan and Baluchistan province, southeastern Iran. There were no consistent differences between sp...
