As the school year kicks off, classrooms are buzzing—and not just with excitement. The Back to School season often brings a spike in common illnesses. From runny noses to more serious viruses, staying informed can help protect your child and give you peace of mind.

Here’s what’s currently going around, what symptoms to look for, and when to seek medical care.

What Illnesses Are Spreading Right Now?

According to the Centers for Disease Control and Prevention (CDC), here’s a quick snapshot of current 2025 trends:

  • COVID‑19: Cases are rising nationwide, especially in school-age children and teens.

  • Whooping Cough (Pertussis): Over 7,000 cases have already been reported this year—more than double the number at this time last year.

  • Measles: Outbreaks are increasing, with the highest number of cases seen since 1992.

  • Flu & RSV: Currently low but expected to increase as we move further into the fall season.

So while flu and RSV aren’t yet peaking, now is a good time to prepare for what’s ahead.

Symptoms to Watch For in Fall 2025

Knowing what to look for can help you act early and avoid spreading illness to others. Below are key symptoms tied to current infections:

Illness Common Symptoms
COVID‑19 Fever, cough, congestion, fatigue, sore throat, body aches
Whooping Cough Cold-like symptoms, then severe coughing fits with a “whoop” sound
Measles High fever, cough, runny nose, red eyes, rash
Flu Sudden fever, chills, muscle aches, fatigue, cough
RSV Wheezing, cough, fast breathing, poor feeding (especially in infants)
Common Cold Runny nose, mild cough, sneezing, sore throat
Stomach Bugs Nausea, vomiting, diarrhea, stomach cramps

 

How to Help Prevent Sickness This Season

Staying ahead of school-year sniffles doesn’t have to be complicated. A few everyday habits can make a big difference in keeping your family healthy—and help your child avoid those missed days of learning and fun.

First, make sure your child is up to date on recommended vaccines. That includes protection against COVID‑19, influenza, measles (MMR), whooping cough (DTaP or Tdap), and RSV, which is now available for certain age groups. Your pediatrician can help you understand what’s right for your child’s age and health history.

Next, focus on reinforcing healthy habits at home. Kids should wash their hands frequently, especially before meals and after using the restroom. Remind them to cover their coughs and sneezes, and try to keep shared surfaces—like doorknobs, remotes, and phones—clean and disinfected. And if your child isn’t feeling well, it’s best to let them rest at home rather than risk spreading illness to others.

Finally, support your child’s immune system by helping them build strong daily routines. That means getting enough sleep, eating balanced meals, staying hydrated, and spending time outdoors for fresh air and movement. These simple foundations can go a long way in helping your family stay well throughout the school year.
