Secondary database originated from the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) containing data from adult patients aged 20 to 89 years admitted to hospital due to SARS by COVID-19 in the pre-vaccination period in Brazil.


Steps to reproduce

From an initial sample of over a million patients registered in SIVEP-Gripe in the pre-vaccination period in Brazil, we included in this database data from 313,898 adult patients aged 20 to 89 years admitted to hospital due to SARS by COVID-19 and confirmed by polymerase chain reaction testing (RT-PCR) or antigenic tests. We reviewed the comorbidities to define our study group and split patients into two groups: 1) 164,119 patients without risk factors (BMI < 24.9 kg/m2 or without comorbidities) and 2) 149,779 patients with any composition of the following characteristics: overweight or obesity (BMI ≥ 25 kg/m2), DM, cardiovascular disease CVD (including hypertension and dyslipidemia), or any combination of these risk factors. Any other comorbidity was excluded, as well as pregnant or puerperal women.
