in Nigeria, studies on mpox among primary healthcare workers are scarce despite increasing incidence of mpox disease between 2017-2022. This study aimed to assess primary healthcare workers knowledge and perception of mpox in Nigeria. we conducted a cross-sectional survey among primary healthcare workers in Nigeria (Oyo, Lagos, and Jigawa) to represent different health system capacities and socio-economic contexts. Knowledge of mpox was evaluated in four domains: general knowledge, transmission, signs and symptoms, and prevention and treatment. Each correct response received a score of 1. We categorize the level of knowledge based on the score using the mean score as the cut-off by re-classifying the composite score of respondents for each state into a binary outcome of "good knowledge" if the mean composite score was greater or equals to the mean of overall knowledge score for the three states (16.1), and "poor knowledge" if the mean score equals to sixteen or less than sixteen (≤16). Factors associated with mpox knowledge were explored using multivariable logistic regression at a 5% significance level. Perception of mpox was assessed using five constructs from the health belief model, measured on 3-point Likert scales. Factors associated with each construct were analyzed using Kruskal-Wallis and Mann-Whitney-U tests. in our study on healthcare workers, 78.3% (n=239) were aware of mpox disease. Their overall knowledge was moderate, particularly regarding transmission. Meanwhile, less than 50% knew mpox can be transmitted through sharing utensils, and 65.3% (n=156) understood contact with infected animals could lead to transmission. Lagos had lower overall knowledge scores (15.3±2.3) compared to Jigawa (16.9±2.3) and Oyo (16.3±2.5) (p<0.001). Perceived susceptibility was similar across states (p=0.127), and 97.5% (n=233) believed mpox can affect anyone, while 47.3% (113) felt they couldn't contract it. Jigawa exhibited higher perceived severity (p<0.001) and barriers to prevention (p<0.001). primary healthcare workers in all settings had limited knowledge of mpox transmission, with the perception of mpox varying by state and participants' socio-economic characteristics. The responsibility of HCW encompasses a range of activities that include diagnosis, patient care and education, and public health interventions amongst others. Hence it is important to educate HCWs on mpox disease to successfully curtail the spread of mpox.
