Introduction Acute diarrhoea diseases remain a leading cause of preventable death, especially among under- five children in developing countries. This study assessed the knowledge and practice of diarrhoea disease control among primary health care workers in selected facilities in Bende LGA, Abia State. Methods A facility – based cross sectional study carried out from Jan, 6 – 20, 2020. Data were collected using pre-tested, interviewer administered and semi-structured questionnaire in three sections and analyzed with Statistical Packages for Social Sciences (SPSS) version 21. Frequency tables and chi- square test were done with level of significance at p ≤ 0.05.
Results A total of 150 questionnaires were analyzed. The mean age of respondents was 40.22±8.64, with females, 140(93.3%), married 118(78.7%), and had children 114(76.0%). Knowledge of diarrhea disease was good with overall score >80%. Religion and having at least a child showed statistically significant associations with the knowledge of acute diarrhea (X2 =15.0; P-value=0.002, and X2 =26.0; P-value =0.001 respectively). There was also good promotion of practice of diarrhea control with score >80%. Marital status (χ 2 = 16.8, P-value < 0.001), having at least a child (χ 2 = 12.07, P-value < 0.001), religion (χ 2 = 16.91, P-value < 0.025) and knowledge about acute diarrhoea (χ 2 = 28.025, P-value < 0.001) showed statistically significant associations with the promotion of practice of acute diarrhoea control. Conclusion The respondents showed good knowledge of diarhoea disease and promotion of practice of its control. The major source of information for their knowledge was from workshop trainings. This exemplifies the need for sustained human resource capacity building at the primary health care level
