Different fields of knowledge have faced challenges due to the COVID-19 pandemic. Essential public services serving the population's needs were maintained. Previous studies have addressed the possibility of health hazards from handling solid waste (SW) among trash collection service workers, without introducing any data proving or dismissing those risks. Occupational health is stated in at least 2 of the 17 Sustainable Development Goals. Pearson Coefficient (r) was employed to analyze the correlation between the number of cases of COVID-19 in SW collection workers in the city of São Paulo, considering the district city halls where the COVID-19 patients live and the SW collection workers' route, from March 2020 to March 2021. Employees who collected wastes with COVID-19: 2% collected healthcare SD, 4% worked at the waste transshipment stations, 10% household variable route collection, and 83% in defined routes collecting household wastes. Positive and moderate correlation was confirmed (r = 0.59) between the total number of COVID-19 cases and the trash collection routes, and the number of contaminated COVID-19 workers from their trash collection routes. Considering concessionary companies separately, the correlation found in the Southeastern grouping is 0.77 (positive and high correlation), and the correlation found in the Northwestern grouping is 0.18 (positive but insignificant correlation). The Northwestern grouping's concessionary had implemented more effective occupational health and safety management policies and disclosed them among their stakeholders. Results suggest concern related to occupational health and safety for SW collection workers and substantiating the vulnerability of this essential activity during the pandemic.
