How long does RSV last? The acute phase of RSV generally lasts for about a week, with the worst symptoms coming at around the third and fourth days, then gradually improving. The cough may last for weeks. Children are thought to be contagious for 5-8 days, but some children can infect others for as long as a month.
For most babies and young children, the infection causes nothing more than a cold. But for a small percentage, infection with RSV can lead to serious, sometimes life-threatening problems such as pneumonia or bronchiolitis, an inflammation of the small airways of the lungs.
Respiratory syncytial virus, or RSV, is a viral infection that can cause significant symptoms in infants under the age of 2 years old. However, most infants who get the virus experience cold-like symptoms and recover without issue.
Initial signs of RSV are similar to mild cold symptoms, including congestion, runny nose, fever, cough and sore throat. Very young infants may be irritable, fatigued and have breathing difficulties. Normally these symptoms will clear up on their own in a few days.

Most RSV infections go away on their own in a week or two. There is no specific treatment for RSV infection, though researchers are working to develop vaccines and antivirals (medicines that fight viruses).
People infected with RSV are usually contagious for 3 to 8 days. However, some infants, and people with weakened immune systems, can continue to spread the virus even after they stop showing symptoms, for as long as 4 weeks.
The flu, COVID-19, and respiratory syncytial virus (RSV) are all highly contagious respiratory infections caused by viruses: The flu by influenza virus, COVID-19 by SARS-CoV-2 virus, and RSV by respiratory syncytial virus. It is possible for a person to be infected with multiple viruses at the same time.
RSV, or respiratory syncytial virus, is a seasonal illness that has been commonly overlooked even though it affects about 97% of children by the age of two. This is because the symptoms are similar to that of the common cold and are normally mild. But for some, RSV can be severe and even life threatening.
Breastfeeding confers protection against both incidence and severity of RSV disease, particularly in those born prematurely, as well as the subsequent development of recurrent wheezing illness .
How is RSV treated in a child?
Yes. Viruses like RSV spread on the surface, as though they were contagious. Generally it comes into the body through the nose or eyes, or indirectly from nasal discharge, saliva, mucus, or contact with the mouth or pharynx.
When your pediatrician listens to your baby's lungs, if they have RSV and bronchiolitis, it actually sounds like Rice Krispies in the lungs; it's just all crackly.
Both Janssen and Pfizer have run small-scale challenge trials, exposing vaccinated younger adults to RSV, and have shown that their vaccines protect against infection. The Janssen, Moderna and GSK vaccines increased levels of neutralizing antibodies 9–15-fold.
Respiratory syncytial virus enters the body through the eyes, nose or mouth. It spreads easily through the air on infected respiratory droplets. You or your child can become infected if someone with RSV coughs or sneezes near you. The virus also passes to others through direct contact, such as shaking hands.
