Assessment of potential factors that support the endemicity of cholera in Nigeria from food handlers, health workers and the environment

Abstract

Background and Aims: Diarrheal diseases caused by bacterial pathogens are widespread and they result in morbidity and mortality of a lot of people yearly. The aim of this study was to assess the role of the environment, health workers and food handlers as reservoirs of Vibrio cholerae, and other diarrhea causing bacteria. Methods: Healthcare workers were proportionally selected and multistage sampling technique was adopted in selecting food handlers for the study. A total of 374 participants consisting of health workers and food handlers were recruited. Socio-demographic and clinical information were collected using questionnaires, while stool and environmental samples were also collected. Results: More female 55.9 % than male 44.1 % participated in the study and the mean age of participants was 38.7 ± 10.9. A significant number of participants identified poor hygiene practices as the major cause of diarrhea. V. cholerae O1 serotype was not detected in any of the environmental samples nor stool samples of both food handlers and health workers. However, V. cholerae (Non O1/Non O139) was isolated from the stool samples of food handlers and health workers in Kano State implying that they could be serving a source of the continuous dissemination of the pathogen. Other bacterial pathogens that are aetiology of diarrhea including Salmonella spp. Escherichia coli, Klebsiella oxytoca, and Enterobacter spp. were also isolated. Conclusion: It is therefore imperative that food handlers and health workers undergo periodic health checks to ensure they are free of pathogens they could easily transmit through food or to patients.

Knowledge about cholera and its prevention among household heads in a highly urbanized city in Western Philippines: a cross-sectional study

“…Similarly, the study by Tutu, Gupta and Busingye (2019) revealed that females had a higher score on basic knowledge of cholera risk factors in Ghana. The finding of the present investigation is also congruent with those of Samuel Amoo et al (2021) in Nigeria, Akabanda, Hlortsi and Owusu-Kwarteng (2017) in Ghana, and Baluka, Miller and Kaneene (2015) in Uganda, where more female food handlers or service workers participated in the study than males because females were more involved in food handling and primary health. Additionally, the study by Serrem et al (2021) in Kenya showed that female food handlers had more knowledge of food safety and sanitation than males.…”
