This study aimed to investigate the prevalence of intestinal helminth infections in humans and detect Toxocara spp. in cats, with a focus on assessing the impact of age and gender on infection rates. Traditional diagnostic methods have historically limited the accurate identification of helminth infections in humans. Analysis of 450 human stool samples revealed an overall helminth infection rate of 5.7% using conventional techniques. The specific infection rates were 0.4% for Strongyloides stercoralis, 0.6% for Schistosoma mansoni, 1.7% for Hymenolepis nana, and 2.8% for Ascaris lumbricoides. Notably, no infections were recorded in the 30–39 and ≥40-year age groups, while the highest infection rate (16.3%, P≤0.01) was observed in individuals aged 20–29 years. With respect to gender, males exhibited a significantly higher (P≤0.01) infection rate (7.5%) compared to females (4%). Additionally, human sera were tested serologically using indirect ELISA for IgG antibodies, with a positivity rate of 10.4%. Age-wise, no positive cases were recorded in the 20–29 year group, while positivity rates of 8% and 24% were found in the 30–39 and >40 year groups, respectively, showing a significant difference (P≤0.01). In terms of gender, females had a significantly higher (P≤0.01) seroprevalence (15.2%) than males (6%). In domestic and stray cats, the overall prevalence of Toxocara spp. was 12%, with a significantly higher (P≤0.01) infection rate in kittens compared to adult cats. This study revealed notable prevalence of intestinal helminths in humans and Toxocara spp. in cats, with age and gender influencing infection rates. The findings emphasize the need for improved parasite control and public health measures to reduce zoonotic risks.
