Objective: To investigate the distribution and clinical characteristics of COVID-19 in individuals treated at health units in the state of Rio de Janeiro, between June and October 2020. Method: Serial cross-sectional observational study with 10,329 participants. Clinical-epidemiological data were collected through an electronic form, with RT-PCR testing for SARS-CoV-2 and IgM/IgG serology. Statistical analysis included data processing in R software, categorization of variables, and use of descriptive tools. Results: Positivity was 14% for RT-PCR, 8.4% for IgM, and 10% for IgG. Women (60%) and mixed-race individuals (45%) predominated. Testing centers had a higher positivity rate (RT-PCR: 16%; IgM: 13%). Headache (41%) and myalgia (33%) were the most common symptoms, while anosmia was reported by 18%. Conclusion: The study highlighted the temporal relationship between diagnostic methods and the clinical profile of COVID-19, highlighting the importance of integrated testing strategies for epidemiological and clinical management.
