dc.description.abstract This study was conducted in EL Gunaid Scheme, Gezira State, to provide some elements of analytical micro-epidemiology with special emphasis on parasite aggregation and dynamics related to the knowledge, attitude and practice of the people. One parasitological survey was conducted, where the school children of seven villages and four camps were examined microscopically, for schistosomiasis and intestinal parasites. A pre-tested questionnaire was conducted to assess some socioeconomical factors influencing transmission pressure of the aforesaid parasites. Considering human as an essential unit of study, array of variables that highlighted the socioeconomic status of the households and the villagers' style of life were related to the infection parameters e.g. age-classes, gender, occupational category and educational level. All infected school children were treated under medical supervision with intensive health education programme. The previously adopted control approach in reduction of infection parameters of Bilharzia and intestinal parasites was evaluated. The sensitivity of the direst smear and the modified Kato techniques was assessed, qualitatively and quantitatively. The overall situation of intestinal schistosomes among the school children in the scheme was very notorious, prevalence rate of 27.3 % and intensity of 108.4 eggs per gram of faeces. Residentially, the school children in camps have the lion-share in infection rate, 45.3%, and worm burden, 182.9 eggs per gram of faeces. The least suffering children were resident in villages outside the ramified canalization system, prevalence (10.1%) and intensity (41.0 epg). The males' infection rates (31.4%) and worm burden (131.7 epg) outnumbered those among the females (23.4% and 85.0 epg). The age-class distribution of the intestinal schistosomiasis in the scheme showed the conventional curve, where the two parameters increased to a sudden apex at (15-19 years), 40.1% and 171.5 epg, respectively. The average of the worm burden in the scheme, expressed in eggs excreted, was 108.4 epg, but unfortunately, the average of the most suffering group was 418.8 epg. Considering the ethnicities in the scheme, 52.1 % of examined children were from southern-origin was found to be highly infected with a high worm burden, 282.2 epg. On the other hand, the children from the eastern-roots were ensured to be the least suffering, in terms of the worm burden, 20 epg. The finding of the survey suggested a low level of success of the adopted tools for combating schistosomiasis among the school children. Unfortunately, the overall prevalence rate in the scheme was reduced by 11.9%, while the overall intensity was increased by 58.7%. The prevalence rates were declined in moderately and heavily infected children with 47.6 % and 32%, respectively. On the other hand, the proportion of the lightly infected children was increased with average of 39%. The overall prevalence rate of the intestinal parasite was 11.0%, where predominated by H. nana, 6.71%, followed by E. vermicularis, 3.2%, then A. lumbricoides, 0.9% and Taenia sagenata, 0.2%. All infected children with tapeworm were resident in the camps, while the only monitored case of the hook worm was from El Engaz camp. Around one-quarter (23%) of the camps' children suffered from one or another intestinal parasite, excluding Bilharzia. The school children inside the irrigated area were less suffering, in terms of prevalence of infection, followed by villager outside the scheme, 8.6% and 1.4%, respectively. El Engaz Basic School was selected for a special study to assess the efficiency of the direct-smear technique with that of the modified Kato technique in detection intestinal schistosomiasis. In both infection parameters, the modified Kato technique significantly outnumbered the direct-smear technique. The sensitivity of the direct-smear technique significantly varied in detection of both prevalence and intensity, throughout the three consecutive samples. The logistic serious control programme for considerable reduction of the infection parameters of the aforementioned infections was discussed. Finally, based on the finding suggestions, some effective measures for combating the investigated parasites were highly recommended en_US
