Hospitalization cost estimates of respiratory syncytial virus and influenza infections in adults in Spain, 2016-2019.

Respiratory syncytial virus (RSV) is increasingly a recognized cause of severe respiratory infection among adults. This retrospective observational study compared the costs of RSV and influenza hospitalizations in adults aged ≥18 years admitted to the Spanish National Healthcare System between 2016 and 2019. Mean costs per hospitalization episode were compared using a multivariable log-gamma generalized linear model adjusted by age, risk group and calendar year.

Economic burden of children hospitalized with respiratory syncytial virus infection in Spain, 2016-2019.

This retrospective observational study aimed to quantify the costs associated with hospitalized respiratory syncytial virus (RSV) in children <18 years admitted to the Spanish National Healthcare System between 2016 and 2019 and contrast them with the costs of unspecified bronchiolitis/bronchitis/pneumonia (UBP) and influenza. The mean cost per hospitalization episode was reported by age group, risk category and prematurity. Total annual hospitalization costs were calculated from population incidence rates and the mean cost per episode.

Differences Between RSV A and RSV B Subgroups and Implications for Pharmaceutical Preventive Measures.

Introduction: Understanding the differences between respiratory syncytial virus (RSV) subgroups A and B provides insights for the development of prevention strategies and public health interventions. We aimed to describe the structural differences of RSV subgroups, their epidemiology, and genomic diversity. The associated immune response and differences in clinical severity were also investigated.

Pediatric Respiratory Syncytial Virus Diagnostic Testing Performance: A Systematic Review and Meta-analysis.

Background: Adding additional specimen types (eg, serology or sputum) to nasopharyngeal swab (NPS) reverse transcription polymerase chain reaction (RT-PCR) increases respiratory syncytial virus (RSV) detection among adults. We assessed if a similar increase occurs in children and quantified underascertainment associated with diagnostic testing.

Methods: We searched databases for studies involving RSV detection in persons <18 years using ≥2 specimen types or tests.

Underascertainment of Respiratory Syncytial Virus Infection in Adults Due to Diagnostic Testing Limitations: A Systematic Literature Review and Meta-analysis.

Background: Most observational population-based studies identify respiratory syncytial virus (RSV) by nasal/nasopharyngeal swab reverse transcriptase real-time PCR (RT-PCR) only. We conducted a systematic review and meta-analyses to quantify specimen and diagnostic testing-based underascertainment of adult RSV infection.

Methods: EMBASE, PubMed, and Web of Science were searched (January 2000-December 2021) for studies including adults using/comparing >1 RSV testing approach.
