ABSTRACT
The present work was implemented to determine the current status of Schistosorna mansoni infection in "El-Prince" village, near Alexandria, which was studied before as a Control village between 1985 and 1990. Stool examination was performed on 571 of the inhabitants by Kato thick smear technique and intensity of infection was determined. Prevalence was found to be 15.4% with a percentage decrease of 53% from the 1990 survey. The geometric mean egg count [GMEC] ranged from 19.05 eggs/gram of stools in children aged five years or less to 81.86 in the oldest group greater than 50 years of age and averaged 42.26. Age stratified prevalence of infection peaked at 31.4% in the [20 to 25]-year-old age group. High prevalence of 23.6% was also observed in the age group from 36 to 50 years. Infection in males was higher than females [17.8% vs.13.5%]. However the difference was not statistically significant [x2 = 2.2, P=0.0086]. Risk factors significantly associated with the infection were an age more than 5 years, male gender, males with water contact activities and having done a previous lab oratory analysis for schistosomiasis. The community category of the village changed from high prevalence in 1990 to moderate prevalence in 2002. Most of the infected individuals [85%] had light intensity of infection [less than 99 eggs lg stools]. Active screening and treatment programs should be maintained in the area. More control measures should be directed towards older people who should be included in evaluation of control programs
