Heavy burden of intestinal parasite infections in Kalena Rongo village, a rural area in South West Sumba, eastern part of Indonesia: a cross sectional study

BACKGROUND Intestinal parasitic infections (IPIs) are one of the major public health problems, especially in the rural area of developing countries with low socio-economic status and poor sanitation. The study was aimed to determine the prevalence of IPIs among the inhabitants of a rural area in South West Sumba, eastern part of Indonesia. METHODS A cross-sectional study was done in Kalena Rongo village, South West Sumba in April 2014. Stool samples were collected and examined for IPIs using direct smear method. RESULTS Faecal samples were collected from 424 of 473 inhabitants of the village, age 2 months to 80 years. About 95.5 % (405/424) of the participants had any IPIs. The most prevalent parasites found were Ascaris lumbricoides 65.8 % (279/424), Trichuris trichiura 60.4 % (256/424), hookworms 53.5 % (227/424), Blastocystis hominis 34.4 % (146/424), Entamoeba histolytica 17.9 % (76/424), and Giardia lamblia 4.5 % (19/424). The villagers used no latrine and defecated in their backyard. Clean water sources were scarce and far from the village. CONCLUSIONS In Kalena Rongo village, the rural area in eastern part of Indonesia, the finding of IPIs was conspicuous and therefore expressed the poor hygiene and absence of proper sanitation in the area. Integrated efforts, such as improving infrastructure to provide clean water source and educating the inhabitants for appropriate hygienic lifestyle are needed.
