UNLABELLED Respiratory syncytial virus (RSV) is responsible for annual respiratory infection outbreaks in infants and young children worldwide, frequently causing bronchiolitis and pneumonia. We evaluated clinical and epidemiological features of acute respiratory infections (ARIs) caused by respiratory syncytial virus (RSV) in children less than five years old. Nasopharyngeal aspirate samples f...

BACKGROUND Seasonal influenza viruses and respiratory syncytial virus (RSV) are primary causes of acute respiratory tract infections (ARTIs) in children. New respiratory viruses including human metapneumovirus (hMPV), human bocavirus (hBoV), and influenza 2009 A(H1N1) virus have a strong impact on the pediatric population. OBJECTIVES To evaluate epidemiological and clinical features of ARTIs ...

BACKGROUND Respiratory syncytial virus (RSV) is the most important cause of severe acute respiratory tract infection in young children. Alere i RSV is a novel molecular rapid test which identifies respiratory syncytial virus in less than 13 min. METHODS We evaluated the clinical performance of the Alere i RSV assay in a pediatric point-of-care setting during winter season 2016 / 2017. Test re...

BACKGROUND A large number (17) of nosocomial respiratory syncytial virus cases led to the development of control measures to prevent transmission of respiratory syncytial virus (RSV) within the Johns Hopkins Hospital's Children's Center. METHODS The control plan is based on a 2-stage process. In stage 1, the staff are notified that RSV is in the community, and information is distributed throu...

BACKGROUND Influenza virus and respiratory syncytial virus (RSV) are among the most common viruses causing infections of the lower respiratory tract in young children. Although there are important differences in the immunopathogenesis of these 2 viral pathogens, little is known about how they affect antigen-presenting cells in children with acute infections. METHODS To characterize the immune...

Respiratory syncytial virus (RSV) is known to cause acute lower respiratory tract infections (ARI) in young children and is involved in exacerbation of chronic obstructive pulmonary disease (COPD) in adults. The role of RSV in stable COPD and the viral load in different respiratory diseases has not been investigated to date. The present authors established and evaluated a quantitative TaqMan re...

BACKGROUND The objective of this study was to evaluate the effects of breastfeeding on the severity of respiratory syncytial virus infection in early infancy. METHODS A rapid test for respiratory syncytial virus (RSV) was administered by 16 general pediatricians from May 2002 to April 2005 in infants undergoing medical checkups for the common cold, all of whom were 100 days old or younger and...

A recombinant human antibody fragment, designated RSV Fab 19, efficiently neutralizes respiratory syncytial virus (RSV). Here we report the results of our sequence analysis of antibody escape mutants that identified F glycoprotein amino acids critical for binding of human or murine RSV F-neutralizing antibodies.

2'-5'-Oligoadenylate synthetase-like protein (OASL) is an interferon-inducible antiviral protein. Here we describe differential inhibitory activities of human OASL and the two mouse OASL homologs against respiratory syncytial virus (RSV) replication. Interestingly, nonstructural protein 1 (NS1) of RSV promoted proteasome-dependent degradation of specific OASL isoforms. We conclude that OASL act...

Respiratory syncytial virus (RSV) is a common cause of seasonal respiratory viral infection in patients who have undergone hematopoietic stem cell transplantation. RSV usually presents as an upper respiratory tract infection in this patient population but may progress rapidly to lower respiratory tract infection. Available therapies that have been used for the treatment of RSV infections are li...
