Abstract :
[Background]Nowadays, intestinal parasitic infections (IPIs) are one of the most common and serious public health problems, which affected 3.5 billion people worldwide, especially in developing countries. During the time of distribution, the pattern of disease may alter as a result of changing the life style of residents.[Objectives]The current study was aimed to determine the prevalence of IPIs in the town of Haftkel, southwest Iran.[Methods]In this descriptive cross-sectional study, 13698 stool specimens were collected during 2010 - 2013. For all samples, both direct smear and formalin ether concentration methods were done. Finally data analysis was performed using SPSS version 11.0.1 (SPSS Inc., Chicago, IL, USA).[Results]658 (4.8%) out of 13698 specimens were positive for IPIs and Giardia lamblia was detected in 433 (3.16%) samples as the commonest parasite. Other parasites were included: Entamoeba histolytica/dispar (0.7%), E. coli (0.56%), E. hartmanni (0.21%), Blastocystis hominis (0.1%), Hymenolepis nana (0.04%), Taenia spp (0.014%), and Enterobius vermicularis (0.007%). A decreasing trend was observed in the prevalence of intestinal parasites in which the frequency was 281 (6.42%) cases in 2010 and declined to 114 (3.83) in 2013. The maximum and minimum infection was seen in the summer season (34.35%) and winter (15.35%), respectively. Furthermore, the number of infected men was significantly higher than women (64.5% against 35.5%). Interestingly, no hookworm, Ascaris lumbricoides, and Trichuris trichiura eggs were seen in the current study.[Conclusions]Based on the current findings, IPIs particularly helminthic cases have been declined during the past decades. Therefore, health education and improving facilities environmental especially in rural and semi-urban areas can be helpful.
