Objectives: To characterize the study population, estimating the in-hospital lethality rate by state and analysing associated factors with COVID-19-related deaths. Methods: a retrospective cohort study was carried out of hospitalised children and adolescents diagnosed with COVID-19, confirmed by RT-PCR, whose outcome was death by COVID-19 or recovery, from 2020 March 1 to August 1. The data source was the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe in Brazilian acronym), where patients with Severe Acute Respiratory Syndrome (SARS) are notified. Children were defined as those between the ages of 0 and 11, and adolescents those between 12 and 18. A bi and multivariate analysis were performed using Poisson Regression with robust variance, with adjusted Relative Risk as the final association measure. Results: A total of 4,930 cases were analysed; 2,553 (51.8%) were males, 2,335 (47.4%) were brown-skinned. The Federative Unit of Roraima presented the highest in-hospital case-fatality rate, with 68.8% (n=11/16). Multivariate analysis showed that belonging to the age group adolescent (RR = 1.59; 95% CI 1.12 - 2.25; p=0.009), SARS-critical patient (RR = 4.56; 95% CI 2, 77 - 7.51; p<0.001) and presenting immunological disorders (RR = 2.24; 95% CI 1.58 - 3.17; p<0.001) as comorbidities, were associated factors with death by COVID-19. Conclusion: it was observed that adolescents, SARS-critical patients, and presence of immunological disorders were important factors associated with death. Active surveillance and differentiated care are recommended for patients with chronic diseases and special immunological conditions.
