Every parent knows the drill: school starts, and within two weeks, someone in the house has a runny nose, a scratchy throat, or a lingering cough. After a long summer of sunshine and fresh air, the return to crowded classrooms, shared supplies, and new germs can leave kids—and their families—feeling less than their best.
Let’s break down the difference between the common culprits behind those early fall sniffles—and when it’s time to check in with your doctor.
What is the “Back-to-School Crud”?
There’s no official diagnosis for “back-to-school crud,” but most parents and pediatric providers know exactly what it means. It’s the mix of mild, cold-like symptoms that tends to show up in the first few weeks of school, especially after a long break.
Why does it happen? It’s a perfect storm of:
- Germ exposure after months away from large groups
- Disrupted sleep routines as kids adjust to earlier mornings
- Stress or anxiety about the new school year
- Dry air and allergens from indoor settings
- Shared spaces and supplies like desks, water fountains, and lunch tables
The result? Low-grade symptoms that don’t always require medical treatment—but still leave kids feeling run-down.
Cold, Allergies, or Something Else? How to Tell the Difference
Understanding what’s behind your child’s symptoms can help you decide how to treat them—and whether to keep them home from school.

When to Call Your Doctor
While most mild cold symptoms can be managed at home, there are times when it’s important to follow up with your provider:
- Fever over 100.4°F that lasts more than 2–3 days
- Ear pain or tugging at ears (possible ear infection)
- Worsening cough or wheezing
- Shortness of breath or difficulty breathing
- Symptoms lasting longer than 10–14 days without improvement
- Concern about COVID-19, flu, or strep throat exposure
At Northwest Family Clinics, our care team can help you determine whether your child needs a sick visit—or simply some rest, fluids, and extra TLC.
How to Support Your Child Through the Transition
Even when it’s not a full-blown illness, the back-to-school transition can take a toll on your child’s immune system and energy levels. These strategies can help minimize the crud and boost recovery:
- Establish a consistent sleep schedule (most school-age kids need 9–12 hours per night)
- Offer nutrient-dense meals and snacks that support immunity along with good hydration
- Encourage frequent handwashing, especially before meals
- Keep tissues and hand sanitizer handy in backpacks and lunchboxes
- Give them downtime after school to decompress and rest
- Stay on top of allergy medications if environmental triggers are a factor
Prevention is Key
Back-to-school bugs are almost inevitable—but with a little preparation and a lot of handwashing, most families can ride out this seasonal wave with minimal disruption. And when you’re not sure whether to let it run its course or check in with a provider, Northwest Family Clinics is here to help you navigate those decisions with confidence and care.
Whether it’s a cold, allergies, or “just the crud,” you don’t have to figure it out alone.
