Objective: The one of the main objectives of malaria elimination program is protection and expansion of cleared up foci, towards and its final goal which is zero is to cut off the indigenous malaria cases. This study is aimed to assess the effect of foreign immigrants on malaria incidence in some clear up and potential foci in Konarak District, south east of Iran.
Material and methods
In this descriptive-analytic study, the numbers of malaria patients in clear up and potential foci were analyzed in Jahliyan region, located on the route of Pakistani and Afghan migration immigrants, during the 2005 to 2009. Data were described using frequency tables and analyzed by paired T-test. Also some of the development indicators were investigated in order to make sure that they did not change during the years of the study period.
The Annual Parasite Incidence (API) increased from a range of “30 to 142.9” after presence of immigrants in 2007, while it was “0 to 49” three years before their presence. The paired T-test showed a significant difference between the number of malaria cases in the villages from 2006 to 2008 and also 2007 to 2008. Development indicators didn’t have dramatic change during the five years, 2005-09 years.
According to this research, the major cause of increasing malaria in the villages was the presence of foreign immigrants that led to increasing API index in 2008; so, cross border movement foreign immigration is a critical issue point to be considered in the malaria elimination program especially in the cleared up foci.
We are extremely grateful to all who facilitated our field work. Particular thanks are expressed to the officials and respected staff in Konarak District Health Center.
