Evaluation of the case fatality rate in 2 031 309 hospitalised Brazilian patients due to COVID-19: An observational study of the first 3 years of the pandemic in Brazil.

ABSTRACT:

Introduction

Since the beginning of the COVID-19 pandemic, in Brazil, there has been a high rate of deaths, mainly among those who were hospitalised due to the disease and those who needed intensive care units (ICUs) and mechanical ventilation support.
