Risk factors for severe COVID-19 outcomes in LATAM countries in the post-vaccination era: an analysis of national surveillance data in Argentina, Brazil, Colombia, and Mexico.

ABSTRACT:

Background

Identifying cases at higher risk for severe COVID-19 outcomes is essential for tailoring interventions for prevention and treatment. We aimed to determine the factors related to hospitalisation, intensive care unit (ICU) admission, use of ventilatory support, and mortality in four Latin American countries.

Methods
