Comparative Analysis Of Intestinal Parasitic Infections Of Outpatients In Guangxi Medical University Affiliated Hospital In 2005 And 2013

Objective: To understand the hospital's status and trends of intestinal parasitic infections and to provide a reference for prevention. Methods: Stool samples were treated by acid-ether centrifugation; iodine staining and direct-smearing were performed; intestinal parasites were examined under a microscope; characteristics of parasitic infections in population were analyzed using the descriptive epidemiological method. Results: 10 kinds of parasites were detected; the infection rate of clonorchissinensis was the highest, followed by B. hominis, hookworm, whipworm and roundworm in order (x(2) = 131.188, 1261.928, 129.386, P < 0.01); The overall infection rates in 2013 and 2005 were 37.08% and 41.07% respectively, and the infection rate in 2013 was lower than that in 2005 (x(2) = 20.5003, P < 0.01); All the infection rates of clonorchissinensis, hookworm, whipworm and roundworm in 2013 were lower than those in 2005 (x(2) = 18.275, 45.449, 34.855, 12.435, P < 0.01); Both in 2005 and 2013, the male infection rate was higher than that in female (x(2) = 12.859, 24.924, P < 0.01); For male, the infection rate of clonorchissinensis was the highest, followed by B. hominis (x(2) = 313.621, 104.409, P < 0.01); for female, the infection rate of B. hominis was the highest, followed by clonorchissinensis (x(2) = 95.293, 43.357, P < 0.01). For male, the age group of 41 similar to had the highest infection rate of clonorchissinensis in 2005 (x(2) = 5.734, P < 0.05), and the age groups of 31 similar to and 41 similar to had the highest infection rate of clonorchissinensis in 2013 (x(2) = 8.908, P < 0.01); for female, both in 2005 and 2013, the age group of 21 similar to, 31 similar to, 41 similar to and 51 similar to had the highest infection rate of clonorchissinensis (x(2) = 6.508, 5.145, P < 0.05). There was no difference in male infection rate of B. hominis in 2005 (x(2) = 10.134, P > 0.05); in 2013, the age group of 0 similar to had the highest infection rate (x(2) = 3.825, P < 0.05); for women, it was the highest in the age groups of 11 similar to, 21 similar to and 31 similar to in 2005 (x(2) = 10.459, P < 0.01), 0 similar to and 11 similar to in 2013 (x(2) = 53.669, P < 0.01). For Hookworm infection in male, the highest infection rate was found in the age group of 11 similar to 21 similar to and 61 similar to in 2005 (x(2) = 4.547, P < 0.05), 61 similar to and >= 71 similar to in 2013 (x(2) = 4.843, P < 0.05); for female, the highest infection rate was found in the age groups of 51 similar to and 61 similar to both in 2005 and 2013 (x(2) = 5.709, 5.958, P < 0.05). Conclusion: In Nanning city, although there was a decline in the infection rate of intestinal parasites of attenders compared with 8 years ago, the infection rate was still high and intestinal parasites were various; The infection rate of geohelminthes had been reduced to a low level; Clonorchissinensis and B. hominis were still the insect species with the highest infection rate.
