Article Synopsis
- CI-qPCR assays provide a viable alternative to traditional cell culture methods for assessing virus viability in wastewater, specifically focusing on human pathogens.
- The study evaluated three CI-qPCR methods (Crosslinker, TruTiter, and PMAxx) on various viruses like HAdV and SARS-CoV-2, revealing differences in sensitivity and effectiveness between them.
- Findings suggest that while PMAxx struggled with detecting certain heat-inactivated viruses, both PMAxx and TruTiter successfully identified intact viruses in wastewater, showing promise for improving public health monitoring and response to emerging viral threats.
Objective: To describe the implementation of nirsevimab for the prevention of respiratory syncytial virus (RSV)-associated lower respiratory tract disease in a pediatric hospital, focusing on strategies to ensure equitable access and address logistical challenges. Additionally, we aimed to identify predictors of nirsevimab deferral among eligible infants. Patients and Methods: Our hospital implemented a universal immunization campaign to all eligible infants, including those discharged from the newborn nursery, intermediate care nursery (ICN), and neonatal intensive care unit (NICU).

Bacterial and viral infections cause a huge burden to healthcare settings worldwide, and mortality rates associated with infectious microorganisms have remained high in recent decades. Despite tremendous efforts and resources worldwide to explore diagnostic biomarkers, rapid and easily assayed indicators for the diagnosis of bacterial and viral infections remain a challenge. B7 homolog 3 (B7-H3), a member of the B7 family of immunoregulatory proteins, is overexpressed in patients with septicemia, meningitis, pneumonia, and hepatitis.

Recent increases in zoonotic diseases underscore the integration of companion animals into urban environments, posing complex transmission risks and highlighting the necessity of One Health approaches. Respiratory and enteric viruses have been consistently linked to interspecies transmission between humans and animals. This study aimed to assess the circulation of human noroviruses (NoV), human adenoviruses (HAdV), enteroviruses (EV), parechoviruses (PeV-A), human bocaviruses (HBoV), hepatitis A (HAV) and E viruses (HEV), Influenza A and B viruses (Flu A/B), respiratory syncytial virus (RSV), and SARS-CoV-2 in domestic dogs and cats in Brazil to understand potential zooanthroponosis risks.

Background: Respiratory syncytial virus vaccines first recommended for use during 2023 were efficacious against lower respiratory tract disease in clinical trials. Limited real-world data regarding respiratory syncytial virus vaccine effectiveness are available. To inform vaccine policy and address gaps in evidence from the clinical trials, we aimed to assess the effectiveness against respiratory syncytial virus-associated hospitalisations and emergency department encounters among adults aged at least 60 years.
