Respiratory virus cases tick upward: What parents should know

RSV is one of several viruses that may cause respiratory distress in some children and adults.

Respiratory syncytial virus (RSV) is a common virus that has become even more common in recent years — and is causing lots of problems.

RSV cases used to rise predictably in the fall and winter, but are essentially occurring year-round since the pandemic.

What are the symptoms of RSV?

The virus causes cold symptoms such as fever, runny nose, chest congestion, and cough. But RSV symptoms tend to be a bit worse, and last a bit longer, than those from most cold viruses. And for some people, especially infants, it can cause more serious problems. In fact, it is the leading cause of bronchiolitis and pneumonia in children under a year old.

Children, teens, and even adults who have asthma or other lung diseases can also be hard-hit when they catch RSV. So can people with congenital heart disease, neuromuscular disorders like multiple sclerosis or muscular dystrophy, and weakened immune systems. That’s why the increase in cases, and the fact that RSV isn’t just a fall and winter illness anymore, is really unfortunate.

Can RSV be prevented?

A monthly injection of a medication called palivizumab can help prevent the illness. Only certain young children are eligible for it, particularly those who are born prematurely, or have lung disease, neuromuscular disease, heart disease, or a weakened immune system. Talk to your doctor about this if you think your child might be eligible.

While palivizumab is generally given between September and March or April (the months we have traditionally seen cases), the American Academy of Pediatrics (AAP) encourages giving it in the months in between as well, due to the rise in cases outside of those months.

How is RSV treated?

There really aren’t effective medications for RSV infections; all we can do is help people get through it. Most of the time, this means using saline sprays, a humidifier, acetaminophen or ibuprofen, and other things we do for the common cold. But some children need to come into the hospital, usually because of trouble breathing known as respiratory distress.

What are the symptoms of respiratory distress?

Parents should be watchful when children develop cold symptoms. This is especially important for children who have any of the health problems mentioned above.

Watch for any signs of trouble breathing, such as

• a very frequent cough
• audible wheezing
• sucking in around the ribs with breathing
• flaring of the nostrils
• trouble talking, or a weak cry
• pallor or a blue tinge to the skin
• unusual sleepiness or weakness.

If any of those happen, seek medical attention immediately. If none of these are happening but the child has a bad cough or high fever, it’s worth a call to the doctor to check in.

Meanwhile, make sure you and your family cover coughs (with an elbow or a tissue, not your hand) and wash hands often with soap and water or hand sanitizer. While many people have stopped wearing masks, a well-fitted mask can help prevent RSV and other respiratory illnesses. Talk to your doctor about cases of RSV — and COVID-19 — in your community, so that you can make the best decision for you and your family.
