Abstract

The protozoan parasite, Cryptosporidium spp., causes an intestinal illness known as cryptosporidiosis in humans. Watery diarrhea, dehydration and weight loss are common symptoms of cryptosporidiosis, which can last for up to 2 weeks. The present study aimed to investigate Cryptosporidium spp. infection in humans, using the modified acid‑fast staining technique. From November, 2023 to the end of January, 2024, a total of 200 fecal samples were collected from patients of different ages and both sexes. The analysis revealed an infection rate of 60/200 (30%) for Cryptosporidium spp. According to the findings, males had a higher infection rate (32.14%; 36/112) than females (27.27%; 24/88), although the difference was not statistically significant. The study also found a significant association between age and cryptosporidiosis; specifically, patients ≤5 year of age exhibited the highest infection rate at 52.94%, while the lowest rate was 20.83% for the age group of 36‑50 years. As regards residency, the infection rate was higher among rural residents (30.90%) than urban residents (28.88%), with no significant differences between the groups. On the whole, the present study indicates that Cryptosporidium spp. is a critical factor in the causation of diarrhea, particularly in younger patients.
