Prevalence of Enteroparasites Among Non-Saudis in Bahrah, Saudi Arabia.

Abstract

BackgroundEnteroparasitic infections in tropical and subtropical regions of the world are among the most common diseases. The majority of the cases may show no symptoms; however, many untreated cases may experience severe complications. The recent substantial economic development in Saudi Arabia has resulted in an inflow of millions of workers with intestinal parasitic infection, from highly endemic countries, mainly from Asia and Africa.ObjectiveThis cross-sectional study aimed to assess for the first time the prevalence and associated factors of intestinal parasitic infestation among non-Saudi residents in Bahrah, western region, Saudi Arabia.Materials and methodsA total of 355 stool samples were collected from participants included in this study for several examinations of intestinal parasites. In addition, questionnaires including personal data, sociodemographic data, personal hygiene, health habits and other factors were used.ResultsThe prevalence of intestinal parasitic infections among non-Saudi workers in the present study was 22.3%, and the prevalence of protozoan infection was higher than helminth infection. Most of the workers were from Asian countries and were prevalent with Trichuris trichiura, Blastocystis hominis, Endolimax nana and Ascaris lumbricoides. Single intestinal infections were among 86% of the infected cases. The main significant factors associated with intestinal parasitic infections were personal hygiene practices (such as proper handwashing before meals and after using the toilet), source of drinking water and type of living accommodation.ConclusionIntestinal parasites were slightly more prevalent among non-Saudi workers in Bahrah. There is a need for public health awareness programs to prevent spreading of the infections.
