Respiratory syncytial, or RSV, is a common respiratory illness that infects the nose, throat, and lungs.
Adults often experience mild symptoms if they catch RSV. However, while RSV is not typically a serious health issue for most adults, it can cause severe infection in infants, young children and older adults with pre-existing conditions.
For the most part, in patients who are overall healthy, RSV presents as the common cold or a sore throat,” said William J. Pickard, D.O., primary care physician at CHRISTUS Trinity Clinic near Beaumont. “They typically don’t even get a fever. Patients are often unaware when they have it.
It’s natural to worry when your child is sick, especially when it’s hard to tell if it’s a common cold or something more serious like RSV. Jason Harris, emergency medical director at CHRISTUS in Texarkana, said you should seek medical care for your child when you notice signs of strained breathing or concerning symptoms.
Here’s when you should call your pediatrician or go to the hospital:
-
When in doubt, trust your instincts and reach out to your child’s doctor. Acting early can make all the difference.
Most of the time, you will recover naturally, and you can treat symptoms with over-the-counter cold medicines, anti-inflammatories such as ibuprofen, or fever-reducers like Tylenol.
However, in more severe cases of RSV, treatment will depend on what support a child or person needs. Because it is a respiratory infection, children might have trouble breathing. When you have inflammation of the small airways, it increases the risk of breathing problems.
In some cases, emergency rooms will use BiPAP machines, masks that people wear who have sleep apnea, or even a breathing tube and ventilator.
Find an emergency room near you. CHRISTUS Health has emergency care in Texas, Arkansas, Louisiana and New Mexico.
It's not just kids with underlying medical conditions that can get RSV. Even healthy children can get RSV and end up in a pediatric intensive care unit, said Niveditha Balakumar, a pediatric critical care medicine physician who practices at CHRISTUS Children’s.
Healthy babies with no prior medical problems can have trouble with the infection.
However, the most likely people to have severe cases of RSV are:
RSV symptoms are similar to other upper respiratory infections, such as the common cold or flu:
Some, all, or none of the above symptoms may appear in infants with RSV.
A cough of someone with RSV can sound either wet or dry.
But it is different from the croup cough, which is more of a “barking seal cough.” It’s also different from whooping cough, where babies cough repeatedly. With RSV, it can have a lot of mucus and congestion.
RSV can spread quickly because it is highly contagious.
If you are visiting family or friends and have RSV symptoms, you should wear a mask or try to avoid seeing them. This can be challenging around holidays and birthdays, but it is the right thing to do.
“It's just not worth it to get somebody a loved one sick when you didn't know what you had,” Pickard said. “The baby's immune responses aren't as good as ours.”
If you or your child has symptoms of RSV, it is best to stay home from work and keep your children home from school or daycare to stop the spread of RSV. Since RSV is a virus, it just needs to run its course, Pickard said.
However, Dr. Pickard said there is not enough evidence to suggest how long someone who is generally healthy should stay home. But because it is so contagious, wearing a mask is recommended. “I can't stress enough that if someone is sick, and they’re going to be around a baby, just try not to be around them or wear a mask,” Dr. Pickard said.
If you or your children are symptomatic with coughing, congestion and fever, you should stay away from other children, especially babies.
Don’t forget to wash your hands frequently. It’s best to consult your pediatrician for best practices.
If you’re between 32 and 36 weeks pregnant, the CDC recommends that you get the RSV vaccine.
In August 2023, the Food and Drug Administration approved the Pfizer RSV vaccine for pregnant women at 32-36 weeks of pregnancy.
Additionally, on Sept. 2, 2023, the CDC’s Advisory Committee on Immunization Practices endorsed the RSV vaccine for pregnant women at 32-36 weeks of pregnancy. They recommend receiving it during the fall-to-winter months when RSV is most common in the United States.
When administered, the vaccine provides antibodies to you as well as your baby for the first 6 months after birth. It’s a good way to help keep infants safe from RSV-related illnesses in their first few months of life.
For babies who are already born, there’s another recommended measure of protection against RSV. The CDC suggests using an injection called nirsevimab to prevent a virus-related breathing problem known as RSV-associated lower respiratory tract infection.
This injection contains an antibody product that provides protection against RSV and its symptoms.
RSV is a highly contagious virus that is more likely to cause severe illness in infants and older adults. Your baby’s health is a top priority. It’s important to take protective measures for your little one, especially during the peak season of RSV, which is from fall to spring.
You can do this by receiving the RSV vaccine during weeks 32-36 of your pregnancy or making sure your baby receives nirsevimab after they are born. Always talk to your doctor about what is best for you and your baby.
