Paediatric emergencies remain a significant cause of mortality in Nigeria, particularly in rural areas where primary healthcare centres (PHCs) often serve as the sole source of medical care. This study aimed to assess the knowledge gap among healthcare workers in PHCs in Zaria regarding the management of common paediatric emergencies. A cross-sectional descriptive study was conducted among 139 randomly selected healthcare workers in Sabon Gari and Zaria Local Government Areas. A pre-tested questionnaire was used to collect data, which was analysed using SPSS version 21. Results revealed a generally low level of knowledge among healthcare workers regarding both the causes and treatment of common paediatric emergencies. Only a small percentage of respondents demonstrated adequate knowledge in these areas. A statistically significant association was found between academic qualifications and knowledge levels. These findings underscore the urgent need for targeted interventions to improve the skills and knowledge of healthcare workers in PHCs. Collaborations between academic institutions and local health departments can play a crucial role in organising regular training programs to address these deficiencies and enhance the quality of care provided to children in need.
