Respiratory Syncytial Virus

Vaccine efficacy was 68.4 percent against RSV-associated acute respiratory disease; offers protection against subtypes A and B A single dose of mRNA-1345 vaccine is safe and results in lower incidence of respiratory syncytial virus (RSV)-associated disease in older patients, according to a study published in the Dec. 14 issue of the New England Journal of Medicine....

In a comprehensive study spanning eight countries and involving 2401 children over 2 years, four clinical case definitions for respiratory syncytial virus lower respiratory tract infection were evaluated against the World Health Organization’s 2015 criteria.  Respiratory syncytial virus lower respiratory tract infection (RSV–LRTI) poses a significant threat to young children globally, with varied diagnostic criteria...

A recent study explored the correlation between respiratory syncytial virus levels in wastewater and influenza-like illness rates. The emergence of the COVID-19 pandemic has spurred advancements in wastewater-based surveillance (WBS) of respiratory pathogens, offering potential applications in public health surveillance.  This study, conducted in Larissa, Central Greece, assessed the benefits of monitoring respiratory syncytial virus...

Medically reviewed by Dr. Samuel Sarmiento, M.D., MPH on Oct. 4, 2023 This study found a significantly higher burden of all respiratory infections, including respiratory syncytial virus, among Blacks and Hispanics in the United States. Hence, the study confirmed that social inequalities result in a higher risk of respiratory infections, including RSV. This study is a systematic...

Medically reviewed by Dr. Samuel Sarmiento, M.D., MPH on Oct. 5, 2023 A new study shows a significant difference in RSV-related mortality between high- and low-income population groups, which is primarily due to prevalent health disparities globally. Respiratory syncytial virus (RSV) is among the most significant causes of acute lower respiratory tract infection (ALRI) in children below...

Medically reviewed by Dr. Samuel Sarmiento, M.D., MPH on Oct. 4, 2023 RSV causes disproportionate morbidity and mortality in vulnerable populations. A study in Seattle, Washington, found that residents of homeless shelters are more likely to suffer from severe RSV infections and to have co-infections with other respiratory viruses. Respiratory syncytial virus (RSV) is among the leading...

With the recent approval of the monoclonal antibodies palivizumab and nirsevimab and their encouraging results from a current phase III maternal immunization trial, respiratory syncytial virus morbidity and mortality will likely be significantly reduced. Respiratory syncytial virus (RSV) causes most lower respiratory tract infections (LRTI) in children and accounts for over 3.6 million hospital admissions...

Respiratory syncytial virus and other possible non-viral variables may contribute to the clinical severity of bronchiolitis in hospitalized infants.  Respiratory syncytial virus (RSV) is an enveloped RNA virus that is primarily responsible for causing acute bronchiolitis. This viral infection leads to inflammation, characterized by swelling, excessive mucus production, and damage to the epithelial cells. Infants...

In a population of urban children, age was a significant predictor of respiratory syncytial virus and influenza diagnoses. Children frequently contract respiratory viral infections, such as influenza and respiratory syncytial virus (RSV). Their immature immune systems make them more susceptible than adults to these infections. As a result, several variables raise the risk of contracting...
