Recognizing Respiratory Syncytial Virus (RSV) in your Children

Rocky (00:08):
Hi, my name is Rocky.

Tristan (00:09):
I'm Tristan, and our twin sons are Alexander and Diego. The first time we experienced RSV in our family was when Alexander was a little over a year old.

Rocky (00:19):
Alex was gasping forever, like he was drowning in a pool. That's when we, Tristan and I, realized this is something serious that we need to rush him to the hospital. I think we both felt scared at that time because we've never experienced anything like this and we didn't realize what was going on.

Tristan (00:37):
RSV was something we had heard about, but I don't think until you actually experience it, you can really be prepared for exactly how dramatic of a change your kids can go through in a very short period of time. One of the things I think that we were so shocked about RSV is how quickly it became sort of a medical emergency. I think I felt like, what did I do wrong as a parent? What did I miss? What should I have done differently to not get to this point so quickly? And that was a very scary part of RSV and something I was not prepared for.

Rocky (01:14):
The first time that Alex was admitted to the hospital for RSV, we spent about little over a day there.

Tristan (01:20):
Diego then came down with RSV, and that time he also, a few days after getting RSV, he then was diagnosed with pneumonia. And then after that, Diego was in the hospital again with RSV. And then several months later, Alex was in the hospital again with RSV. Each time we were in the hospital with RSV, we knew that, okay, a few days later, the other one will have it.

Rocky (01:47):
The advice I would have for new parents when it comes to RSV, one is trust your instinct when it comes to your child. Be an advocate for them. That's what we did. Two is be aware of where the child sleeps at night when they're sick. Stay close to them. And three, for us, be aware of where the closest hospital is, especially when you're traveling.

Tristan (02:08):
Like Rocky said, be an advocate for your kids, but really push. Try to find a doctor that listens to you. Try to find a doctor that can help you to figure out what do we do and how do we get the best treatment? And how do we know how to best sort of deal with RSV when it happens? Because it's not a matter of if it's going to happen, it's a matter of what it's going to be like when it happens. So as a parent, I wish I would've known more about RSV.

Rocky (02:37):
Again, as Tristan just stated, please contact your pediatrician and ask any questions you may have because it could escalate pretty rapidly.

Tristan (02:46):
Today, the twins are doing great. They are healthy, happy five year old boys that like to play soccer, like to play with toys, that don't like to eat vegetables, and love to play with our friends. So we're very lucky now that we were able to find such great advocates to help us out through the challenges of RSV during the first few years of their lives.

What Causes RSV?

RSV is spread from person to person through close contact with someone who is infected via secretions from coughing and sneezing or touching objects such as toys or doorknobs that have the virus on them.

It takes between two and eight days from the time of exposure for someone to become ill. The illness normally lasts three to seven days, and it is during this time that those infected are most contagious. The peak season for RSV infection in the United States is fall through spring.

Who Is at Risk for RSV?

Most children contract RSV before age two simply because of contact with other children. Being in crowded places with people who may be infected or having exposure to other children or siblings who may be infected are common ways to pick up the virus.

Nearly 100% of infants will contract RSV. While symptoms can be cold-like, they also can be more severe and even life threatening. Contact your healthcare provider should your child develop symptoms. Support for this educational campaign is provided by Sanofi Pasteur.

Nearly 100% of children will be infected with Respiratory Syncytial Virus by age 2. Symptoms can be like a common cold. However, it can be life threatening. Trouble breathing or dehydration are signs of severe illness. RSV is the leading cause of hospitalization of all infants. Contact your healthcare provider if symptoms worsen. Visit lung.org slash rsv to learn more.

Those at increased risk of RSV becoming severe or life-threatening are:

  • All infants or young children born prematurely, with congenital heart or lung disease, weakened immune systems or have neuromuscular disorders.
  • Older adults suffering from lung or heart disease, such as asthma, congestive heart failure, or chronic obstructive pulmonary disease (COPD)
  • People with immunodeficiency, such as organ transplant recipients, chemotherapy patients or HIV/AIDS patients
