Stared into the mirror, flashlight trained on our open mouths, searching for the telltale white patches that typically indicate strep throat. If we see them, we’re off to our primary care practitioner or nearest medical express center for a rapid strep test and, if needed, a course of antibiotics. No big deal.
But when it comes to your baby or toddler, any hint of illness does feel like a big deal.
The fact that untreated strep can cause complications makes the guessing game all the more stressful. That’s why we asked pediatrician Wadie Shabab, MD, FAAP, whether it’s possible for children under 3 to contract strep throat and what worried parents should do if they think their wee one has it.
Acute streptococcal pharyngitis (strep throat) is a highly contagious bacterial infection. It can spread through respiratory droplets or through direct contact, like sharing a cup or touching an infected surface. Strep has an incubation period — the time when you’re contagious but aren’t yet showing any symptoms — of two to five days, which makes it easy to spread, especially in crowded places like schools and daycare facilities.
Strep throat is most common in kids between the ages of 5 and 15. Certain strains of strep throat can cause a red rash known as scarlet fever or a skin infection called impetigo. Luckily, antibiotics can speed up the recovery process and reduce the amount of time a person’s contagious.
Left untreated, strep throat can cause rheumatic fever or a serious kidney problem called acute glomerulonephritis. But these complications are rare. Where we see do see rheumatic fever and glomerulonephritis, it’s usually in resource-poor countries with limited access to antibiotics.
That’s the cloud. Here’s the silver lining: “In general, it’s uncommon for children younger than 3 to have strep throat,” Dr. Shabab says. It’s much more likely that a virus is causing your kiddo’s discomfort.
And there’s more good news: Strep infections also tend to be milder and cause fewer dangerous complications in infants and toddlers than they do in older kids.
While rare, it is possible for a very young child to contract strep throat. And the infection can cause different symptoms than the ones you see in older children and adults. Here are some things to look out for:
Even if your baby ticks most of those boxes, Dr. Shabab says it’s possible a healthcare provider will decide not to test or treat for strep.
Why would your pediatrician opt out of strep testing your sick child? Dr. Shabab says that in addition to contracting strep being rare, the likelihood of complications is also rare.
“We treat strep to decrease the duration of the symptoms and prevent complications such as sinus infections, ear infections and abscesses in the throat area,” he explains. “But the most important reason we treat strep throat is to prevent acute rheumatic fever and acute glomerulonephritis.”
According to Dr. Shabab, it’s very rare for children under 3 to develop these complications, so providers frequently opt not to test and let whatever is happening resolve on its own.
But as with any rule, there are important exceptions to be aware of.
More often than not, a child under 3 isn’t going to have strep throat. But that doesn’t mean there aren’t times when it’s important to be sure.
Your healthcare provider will likely perform a throat swab on your child if they’re ill and:
If your little one’s test comes back positive, their provider might prescribe antibiotics.
The single best way to reduce your risk of strep throat is by practicing good hygiene. Unfortunately, children under 3 aren’t known for their cleanliness. Still, getting your children in the habit of washing their hands for 20 seconds with soap and warm water throughout the day, before eating and after sneezing or coughing is a great first step. And modeling the behavior will help you avoid getting sick, which improves your kiddo’s chances of staying healthy, too!
Here are a few other things you can do to minimize the chances of strep making its way into your home:
It’s rare for children under the age of 3 to get strep throat — and still more unusual for them to get seriously ill as a result. Again, healthcare providers rarely test for it as a result, unless your child is ill and:
Very young children tend not to have the same symptoms as older children with strep throat. If you’re concerned about their symptoms — especially if they have a fever — contact their pediatrician immediately.
