ABSTRACT
Background: Detection and quantification of gastrointestinal parasitic infections (GIPIs) causing public health problems among poorer layers of the society are still one of the Neglected Tropical Diseases (NTDs) in developing countries. Objective: The aim of the study was to detect gastrointestinal parasites among inmates of Social Welfare Homes and Low Socioeconomic Areas in Metropolitan Port Harcourt. Methods: A cross-sectional survey was carried out for the evaluation of all the 1500 participants for GIPs among residents of social welfare homes and low socioeconomic areas in Rivers State, Nigeria for a period of one year (July 2019- June 2020). Stool samples were collected from each participant for isolation of GIPs in stool sample. Formol-ether concentration methods and Modified Ziehl-Neelson Staining techniques was used for the isolation and identification of gastrointestinal parasites. Descriptive and Chi square statistical analysis was applied. Results: Out of 1500, 1,381 (92.1%) participants showed negative report, while 119(7.9%) participants were positive for GIPs. Females account for 839 (55.9%) while males were 661 (44.1%). Positivity in males accounted for 9.8% (65/661) and the females had 6.4% (54/839). Age group with high prevalence occurred among 11-15yrs (13.5%)/340. Both variables were statistically significant (p<0.05). Seasonal distribution of GIPs was high during the wet season (p<0.05). Overall, A. lumbricoides was the most predominant gastrointestinal parasites, accounting for 35.3% of the total identified. Others were as follows; T. Trichiura 26.1%, hookworm 21.9%, C. sinensis and S. mansoni 2.5%, tapeworm 1.7%, while H. nana and H. diminuta had 0.8% each. Co-infection of A. lumbricoides + hookworm and hookworm + T. Trichiura recorded 4.2% each. Protozoa species were not identified. Risk factor of the use of toilet papers was found to be statistically significant (p<0.05) among others. Conclusion: We recommend that knowledge of epidemiology and transmission routes of C. sinensis and H. diminuta needs to be improved and effective health education on personal hygiene and mass treatment should be sustainable to control the spread of gastrointestinal parasites.
