Background and aims: Entamoeba histolytica is an intestinal parasite and a causative agent of
amoebiasis which is a common life-threatening parasitic disease. This study was intended to determine
the prevalence of E. histolytica and to provide the primary data about its infections among the patients
attending Nyanza District Hospital in Rwanda.
Methods: Bottles were used to collect 138 stool specimens from patients. All the samples were physically
analyzed based on their colors, states, and the presence of blood or mucus. The wet preparation
method and zinc sulphate floatation technique were used to concentrate the parasites. Microscopic
analysis was done to examine the presence of cysts and trophozoites. Data were statistically analyzed
by SPSS using chi-square test and independent t test.
Results: The prevalence of E. histolytica was 15.94%. The sex distribution of infections revealed that
males (21.54%) were more infected than females (10.95%). The highest prevalence of E. histolytica
was found in the age group of 1-19 years old (27.11%) and the lowest prevalence was observed in the
age group of 20-39 years old (6.89%). A prevalence of 33.33% was reported among the people who
directly drink tap water and 40% of infections among the patients who did not wash their hands before
eating and after using latrines.
Conclusion: Overall, E. histolytica is still considered as a health burden in Nyanza District Hospital.
Therefore, it is vital to control direct exposure to its risk factors for mitigating the occurrence of
