Respiratory Syncytial Virus (RSV) News and Research

RSS

Respiratory syncytial virus (RSV) causes mild, cold-like symptoms in adults and older children. However, it can cause serious problems in young babies, including pneumonia and severe breathing problems. In rare cases it can lead to death. Premature babies and those with other health problems have the highest risk. A child with RSV may have a fever, stuffy nose, cough and trouble breathing. Tests can tell if your child has the virus.

A viral respiratory infection common in children increases the risk of developing asthma

The study, published in The Journal of Infectious Diseases, is the first to show a link between respiratory syncytial virus, or RSV, infection and asthma in mice. A related study, also in mice, suggests that a medication neutralizing the virus could decrease children's chances of developing asthma.

Respiratory syncytial virus, a common cold virus, can act as a 'hit and hide' virus

An international team of researchers has discovered that respiratory syncytial virus (RSV), a common cold virus causing bronchiolitis in children, can act as a 'hit and hide' virus. It was thought that the virus could only survive in the body for a few days, but these new results show that the virus can survive for many months or years, perhaps causing long-term effects on health, such as damage to the lungs.

Daycare and siblings increase likelihood of contracting respiratory syncytial virus and rhinovirus

Daycare attendance and siblings are associated with viral-induced wheezing in children. Pre-existing immunologic factors may influence the expression of viral infections in infancy, and in turn, recurrent infections may influence the development of immune responses.

Asthma study turns up new information on viral infections

Researchers know that viral infections can exacerbate asthma and, in turn, make people with the condition more sensitive to environmental exposures such as endotoxin. But how viral infections contribute to this sensitivity in airway cells has not been clear. A recent study led by investigators from the University of Iowa Roy J. and Lucille A. Carver College of Medicine and the Veterans Affairs Medical Center (VAMC) in Iowa City shows, for the first time, that viral infections may increase environmental sensitivity in lung epithelial (surface) cells by changing expression of receptors on those cells.
