Discovery could neutralize West Nile virus

Researchers at Vanderbilt University Medical Center and colleagues have isolated a human monoclonal antibody that can "neutralize" the West Nile virus and potentially prevent a leading cause of viral encephalitis (brain inflammation) ...

Researchers identify new compounds to treat RSV, Zika virus

A new and promising class of chemical compounds has major potential for treating Zika virus and respiratory syncytial virus, or RSV, according to a new study by University of Alberta scientists. The next step is to develop ...

Designer nanoparticles destroy a broad array of viruses

Viral infections kill millions of people worldwide every year, but currently available antiviral drugs are limited in that they mostly act against one or a small handful of related viruses. A few broad-spectrum drugs that ...

Targeting a single protein might treat a broad range of viruses

Most drugs that fight viruses are designed to target individual pathogens. But scientists at The Rockefeller University have identified a protein that a broad range of viruses require to spread within a host—a discovery ...

Gene increases the severity of common colds

Researchers funded by the Swiss National Science Foundation (SNSF) have discovered mutations that worsen respiratory infections among children. Their study explain the mechanism involved.

New lung 'organoids' in a dish mimic features of full-size lung

New lung "organoids"—tiny 3-D structures that mimic features of a full-sized lung—have been created from human pluripotent stem cells by researchers at Columbia University Medical Center (CUMC). The team used the organoids ...

Seeing viruses by both light and electron microscopy

Advances in both light and electron microscopy are improving scientists' ability to visualize viruses such as HIV, respiratory syncytial virus (RSV), measles, influenza, and Zika in their native states. Researchers from Emory ...

Imaging technology could unlock mysteries of a childhood disease

By the time they're two, most children have had respiratory syncytial virus (RSV) and suffered symptoms no worse than a bad cold. But for some children, especially premature babies and those with underlying health conditions, ...

Prevalence of colds and pneumonia in cows can be controlled

Respiratory diseases in cattle are a great threat to animal welfare and lead to financial losses in the cattle industry. The bovine respiratory syncytial virus (BRSV) is one of the main causes of respiratory disease in cattle. ...

Human respiratory syncytial virus

Human respiratory syncytial virus (RSV) causes respiratory tract infections. It is the major cause of lower respiratory tract infection and hospital visits during infancy and childhood. There is no vaccine, and the only treatment is oxygen.

In temperate climates there is an annual epidemic during the winter months. In tropical climates, infection is most common during the rainy season.

In the United States, 60% of infants are infected during their first RSV season, and nearly all children will have been infected with the virus by 2-3 years of age. Natural infection with RSV does not induce protective immunity, and thus people can be infected multiple times. Sometimes an infant can become symptomatically infected more than once even within a single RSV season. Severe RSV infections have increasingly been found among elderly patients.

RSV is a negative-sense, single-stranded RNA virus of the family Paramyxoviridae, which includes common respiratory viruses such as those causing measles and mumps. RSV is a member of the paramyxovirus subfamily Pneumovirinae. Its name comes from the fact that F proteins on the surface of the virus cause the cell membranes on nearby cells to merge, forming syncytia.
