Background: Street sweepers are exposed to a variety of risk factors such as dust, bioaerosols, and volatile organic matter, which are responsible for the development of various respiratory symptoms and lung function impairments. However, there is a limited data on the prevalence of respiratory symptoms and associated factors among street sweepers in Ethiopia, especially in the study area. Objective: This study aimed to assess the prevalence of respiratory symptoms and associated factors among street sweepers in Gondar town, northwest Ethiopia, in 2021. Methods: Using simple random sampling technique, a total of 391 workers were selected between August 10 and September 15, 2021. The data was entered and analyzed using the Epi Info Version 7 and Statistical Package for Social Science (SPSS) 22 software, respectively. Descriptive statistics, bivariable, and multivariable logistic regression model were used.
