Background: Despite the burden of disease of Respiratory syncytial virus (RSV) infection in children, there are important gaps in knowledge about the potential impact in terms of health as well as social and healthcare resources. The aim of this study was to describe the economic burden of RSV in the first two years of life in Colombia.
Methods: We conducted a cost-of-illness study, taking a population prevalence-based approach. A decision tree model was constructed with a time horizon of two years. We defined the following outcomes: death, RSV infection with long term complications, RSV with acute complications, RSV without complications. Inpatient and outpatient costs were collected directly from medical invoices of patients who attended a tertiary referral hospital.
Results: The mean cost per patient with an RSV infection was US$ 178.35 CI 95% (30.7-541.67 US$). The total cost of RSV infection in children less than 2 years in Colombia was US $ 64 443 616 per year (CI 95% US$11 092 902 - US$195 722 867). In the probabilistic sensitivity analysis, the mean cost per patient with RSV infection was only sensitive to changes in the cost of recurrent wheezing, cost of outpatient visits and cost of hospitalizations.
Conclusion: The infection by RSV in Colombia generates a high economic burden on the health system. Generating comprehensive data on healthcare resource use and costs associated with RSV will help to provide valuable information for the development of cost-effectiveness models, and help guide prevention strategies against RSV.

Background: Multiple prophylactic products are now available to protect against respiratory syncytial virus (RSV) in different age groups. Assessing the pre-intervention burden of RSV infections across various severity levels and risk groups is crucial, as it provides a baseline for evaluating the impact of these products.
Methods: We obtained monthly time series data on hospitalizations, intensive care unit (ICU) admissions, and deaths by age group, ZIP code, and cause for New York state from 2005 to 2019.

Background: Respiratory syncytial virus (RSV) is a common aetiological agent that causes respiratory infections, especially among infants. Identifying circulating RSV genotypes is an essential strategy for understanding the spread of the virus in a certain area. Sequencing the variable regions of the attachment glycoprotein (G) gene of RSV is a quick and direct approach for identifying the genotypes.

Respiratory syncytial virus (RSV) infections in elderly individuals are associated with increased rates of severe clinical disease and mortality compared to younger adults. Age-associated declines in numerous innate and adaptive immune parameters during RSV infection contribute to infection susceptibility, impaired viral clearance, and distorted cytokine profiles in the elderly. Impaired immune responses in this age group also adversely affect longevity of RSV immunity following vaccination in experimental settings.

Background: Data on the natural history of the community-acquired RSV in adult outpatients are limited. It is also unclear whether the existing influenza surveillance platforms based on influenza-like illness (ILI) case definitions are efficient for RSV. The two-season RESPIRA-50 study was established in 2023 to identify an optimal RSV case definition and to explore the natural history of RSV.

Quantitative polymerase chain reaction (qPCR) is a well-recognized technique for amplifying and quantifying nuclear acid, and its real-time monitoring capability, ultrahigh sensitivity, and accuracy make it a "golden-standard" tool in both molecular biology research and clinical diagnostics. However, current qPCR tests rely on bulky instrumentation and skilled laboratorians in centralized laboratories, which spatially and temporally separate the sample collection and test, leading to longer sample turnaround times (TATs) and limited working conditions. Herein, we propose an integrated optical fiber real-time polymerase chain reaction (iF-PCR) system that successfully allows convenient sample collection, rapid thermocycling, closed-loop thermal annealing, and real-time fluorescence detection in a tiny capillary reactor.
