Runny nose, fever and coughing: In many ways, the symptoms of respiratory syncytial virus (RSV) sound like your typical cold. But, because the virus affects kids’ breathing, it can be quite serious. Kate from Connecticut knows this all too well. Her daughter, Emily*, contracted RSV when she was two years old. She knew it was more than a common cold when her daughter starting having trouble breathing. When she took Emily to the doctor, her oxygen levels weren’t where they should be if she were healthy. When Emily’s condition worsened, she was taken to the hospital. “It’s a scary thing, especially because it affects kids when they’re so little,” says Kate. During Emily’s hospital stay, she was given medicine to help relax her bronchial tubes and help her breathe better. After a day of fluids and rest, Emily was discharged and able to recover at home.
So what is RSV, and how can you protect your child? Here’s everything a parent needs to know.
Your ultimate guide to the most common kid illnesses What is RSV?
RSV is an infection of the lungs and respiratory tract. There are two different strains of the virus, and they can lead to different levels of severity. According to the Centers for Disease Control and Prevention (CDC), almost all children catch the virus by the time they’re two, and an estimated 57,000 children under five are hospitalized each year in the United States for RSV. Much like cold and flu season, RSV season lasts from November through April. And the virus doesn’t discriminate, affecting all age groups, from babies to the elderly.
How is RSV spread?
RSV is highly contagious and can be spread in many different ways. “Droplets from a runny nose, coughing and sneezing are all common ways that RSV is spread,” says TJ Gold, a paediatrician at Tribeca Pediatrics in New York City. Gold says the virus can also live on surfaces in the home, such as doorknobs, countertops, cribs and baby toys, for several hours. According to the CDC, if your baby has the virus, she can be contagious for three to eight days after getting infected.
What are the symptoms of RSV?
One of the tricky things about RSV is that you don’t see symptoms until about four to six days after your child is exposed, but there are symptoms that parents should watch for. “RSV is a virus that produces a lot of mucus,” says Gold. If your baby has a lot of mucus, that’s a classic first sign of RSV—though that’s also symptomatic of a cold. Unlike a cold, though, if your baby has RSV, she could have difficulty breathing. Here are the most common symptoms of RSV:
-A runny nose
-Wheezing or difficulty breathing (listen for a high-pitched noise when your baby is breathing, and watch your child’s chest to see if her skin or muscles pull in with each breath)
While you may start to notice these symptoms after the incubation period is over (three to four days after exposure), Gold says that RSV doesn’t hit its peak until day five or six. For most kids, RSV symptoms last for one to two weeks, but you may notice a residual cough for weeks after other symptoms have cleared up.
How is RSV diagnosed?
When doctors examine a patient who is suspected of having RSV, they look for a lot of secretions, such as mucus. A doctor will also listen to a baby’s chest. Patients with RSV will have scattered wheezing in their chests, and many will pant or breathe extremely fast, says Gold. A nasal swab is done to confirm if a child has RSV. An oxygenation test, done on the finger, may also be performed to see how your well your child’s lungs are functioning.
How do you treat RSV?
Since RSV is a virus, antibiotics aren’t a treatment option. There is an RSV-specific inhaled breathing treatment of humidified saline that your doctor can administer through a mask and nebulizer machine. It’s not 100 percent effective, says Gold, but it can help with the RSV-related breathing issues that some kids experience. However, the treatment has to be administered at your doctor’s office. Acetaminophen or ibuprofen can be taken to help reduce your baby’s fever and pain, but check the label to make sure that you’re giving the right dose for your child’s weight.
As with many other viruses, RSV needs to run its course, which, unfortunately, can be a long while. “Residual coughing and sneezing can last for four to six weeks,” says Gold. For some kids, especially babies less than six months old, the symptoms of RSV can worsen, and a hospital stay may be necessary to treat their symptoms. If your baby isn’t breastfeeding or bottle feeding well, she may become dehydrated and need to be hospitalized and put on an IV to restore her fluid levels. If your child is breathing at twice her normal rate, take her to the doctor or nearest hospital. With RSV, it’s not uncommon for your baby’s oxygen levels to be low, so she might need be put on oxygen in the hospital.
How can I make my baby more comfortable?
Besides lots of TLC, here are some ways to keep your baby comfy. While it may not seem like much, these strategies, combined with plenty of rest, can help your baby feel better.
-Use a humidifier: Concentrated humidified air can help ease your baby’s coughing and stuffy nose.
-Offer plenty of liquids: Babies can become dehydrated because RSV causes them to breathe so fast. Your baby probably won’t want to eat as many solids, so try breastfeeding or bottle feeding more frequently for shorter periods of time.
-Hold your baby in the shower: The steam from the shower can serve as a natural way to improve breathing.
Can RSV turn into something more serious?
Gold says to watch for the main symptoms of RSV, such as difficulty breathing and poor feeding, to worsen. When babies have difficulty breathing, it’s harder for them to feed from the breast or bottle. “Children can get dehydrated, so parents should watch for decreased urine output and poor feeding as signs that RSV is worsening,” says Gold. If you notice these symptoms, visit your doctor or the emergency room immediately.
RSV can reduce your child’s immune function and make her more susceptible to other viruses. According to the CDC, pneumonia and bronchiolitis are two illnesses that children with RSV can catch. With pneumonia, the lungs become infected, while bronchiolitis involves inflammation of the small airways in the lungs.
Viral pneumonia, like RSV, is a virus that just has to run its course. But if your baby has bacterial pneumonia, your paediatrician will prescribe antibiotics. Bacterial pneumonia can be quite serious and may require hospitalization, says Gold. Bronchiolitis is also a virus, but saline drops and acetaminophen can help ease your child’s symptoms. Watch out for signs of dehydration and laboured breathing because, like RSV, your baby may need a hospital stay to restore her fluids and stabilize her oxygen levels.
How can I prevent my baby from getting RSV?
As with colds, there isn’t one magical thing you can do to prevent RSV, but you can take measures to minimize your risk.
-Wash your hands: Since you’re preparing your baby’s food and doing pretty much everything else for her, be sure to wash your hands. Wash them before you pick up your baby and whenever you handle anything that’s going in her mouth.
-Keep surfaces clean: Since RSV lives on surfaces, be sure to wipe down anything that your baby will come in contact with, including toys (we know that’s a lot!).
-Keep your baby away from sick people: You wouldn’t intentionally let your baby hang around with other babies or grown-ups who are sick, but once you know someone is ill, it’s time to go.
If your baby has picked up RSV before, she can still get it again—even during the same RSV season—so be proactive about prevention.
Is there a vaccine for RSV?
There is an injection called Synagis that contains virus-fighting antibodies. It’s only given to babies who are at high risk of developing complications from RSV. These include babies with the following conditions:
-Congenital heart disease
-Chronic lung disease
Unlike a vaccine, babies who receive Synagis need to get an injection once a month, every month, during RSV season. Your paediatrician will be able to tell you if Synagis is suitable for your baby.
Remember, only you know your baby best. If your intuition tells you that something isn’t right, act on it and see your paediatrician so that a proper diagnosis can be made.
