Prevalence Rate of Intestinal Schistosomiasis with Interaction of Other Factors in New Halfa City-Eastern Sudan

Abstract

This study was conducted to determine the prevalence of intestinal schistosomiasis in New Halfa city in Eastern Sudan. Cross-sectional study was carried out during the period March 2011 to October 2011. A total number of 770 surveyed population (age between 4-85 years old, mean age was 23 ± 19 years) were investigated in this study. Faecal specimens, clinical, parasitological and epidemiological data were obtained and recorded. One hundred twelve out of 770 (14.5%) faecal specimens were positive for Schistosoma mansoni (46 (6.0 %) were males and 66 (8.6%) were females) when examined by direct wet mount and Kato-Katz technique. The study also showed that the prevalence of schistosomiasis was high among the age group between 4-12 year. This study compared the infection in treated and untreated groups, the prevalence of infection among the previously treated group found to be (5.2%) and the untreated group showed relatively lower prevalence. The study also showed that out of 770 surveyed population, 88 (11.4%), 103 (13.4%), 183 (23.8%) and 1 (0.1%) were positive for Hymenolepis nana, Giardia lamblia, Entamoeba histolytica and Taenia saginata respectively. Using direct wet mount technique, 21 (19.0%) of the positive cases of S. mansoni showed no co- infections compared to 91 (81.0%) with co-infections included H. nana, G. lamblia, and E. histolytica detected in 22 (20.0%), 26 (23.0%) and 43 (38.0%) cases respectively. The co-infection within all studied population were (3.0%), (3.0%) and (6.0%) also respectively. This study indicates that the area under investigation is endemic for S. mansoni and S. mansoni co-infection.
