Trends and estimated costs of hospitalizations potentially associated with respiratory syncytial virus among children in Brazil, 2014-2025

ABSTRACT Background: Respiratory syncytial virus, a major cause of respiratory infections and hospitalizations in young children, especially bronchiolitis, is an important burden to the health system in Brazil. This study evaluated the trends, seasonality, and economic impact of hospitalizations associated with respira...

A two-step RT-LAMP workflow combining colorimetric screening and lateral flow assay for rapid differentiation of SARS-CoV-2 and influenza A.

Several infectious diseases share overlapping clinical symptoms and transmission routes despite being caused by distinct pathogens. Consequently, diagnostic tests capable of differentiating these infections are crucial for minimizing clinical and epidemiological misdiagnoses. However, the simultaneous detection and dis...

Respiratory viral co-detection in paediatric SARS-CoV-2 infection: associations with viral co-circulation and clinical phenotypes

BACKGROUND Respiratory viral infections in children are characterised by the co-circulation of multiple viral pathogens, but the relevance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) co-detection with other respiratory viruses remains unclear. OBJECTIVES To evaluate the clinical and epidemiological...
