Clinical and Epidemiologic Characteristics of Infants Hospitalized with Respiratory Syncytial Virus Infection During the 2022–2023 Season in Mexico

Abstract

In 2022, several countries reported an increase in respiratory syncytial virus (RSV) infections. We assessed the clinical characteristics and outcomes of infants hospitalized with RSV and compared them with infants hospitalized between 2009 and 2015. No significant differences in underlying disorders, intensive care unit admission rates and mortality were observed suggesting currently circulating RSV strains do not show heightened virulence.
