New backpacks, new teachers, and (almost without fail) a brand new round of classroom germs. If it feels like your child brings home a cold within the first couple of weeks of school every single year, you’re not imagining it. This year, pediatric health forecasters are pointing to an especially early and aggressive start to the Minnesota cold and flu season.
According to a back-to-school 2026 forecast from pediatric health systems, this year is expected to bring an early, strong rhinovirus wave along with a noticeable spike in classroom pink eye outbreaks, followed by the usual RSV, flu, and COVID waves in October and November. And last winter gave Minnesota families a real preview of how rough a bad respiratory season can get.
The good news is that taking a few easy, proactive steps ahead of time can go a long way toward keeping your kids (and entire families) healthier this fall, and can help keep them in the classroom instead of on the couch. This back-to-school health checklist covers everything you need to know about immunizations, sports physicals, and how to decide when a sick kid should stay home and rest.
What’s Circulating This Back-to-School Season
Rhinovirus, which is the virus that’s behind the common cold, is almost always the first thing to spread once the classrooms fill back up. It can easily survive for days on end on hard surfaces like desks, water bottles, and Chromebooks, and in young kids it can lead to wheezing or croup on top of the usual runny nose and cough. This year’s forecast also mentions an increase in pink eye (conjunctivitis) cases, which is going to be largely caused by the adenovirus that will be circulating alongside the early cold wave.
From there, the usual fall and winter lineup can be expected as RSV, influenza, and COVID-19 tend to pick up in the months of October and November. RSV, in particular, can end up becoming a lot more than just a bad cold for infants and toddlers, and the Minnesota Department of Health keeps a very close eye on it each season because of how serious it can become for very young children and older adults.
Last Winter’s Minnesota Flu Season Was a Wake-Up Call
If last winter felt unusually brutal around your house, you were in good company. A Star Tribune report on the season found that a wave of influenza caused 2,946 hospitalizations and 32 deaths in Minnesota, with 176 school outbreaks reported at the peak. Twin Cities clinics and emergency rooms saw some very long wait times as the wave moved through, and school outbreaks predictably declined during the holiday break before picking right back up again when the kids returned to class.
That kind of season is the exact reason that we wanted to put together a back-to-school health checklist this year. A little preparation now can make a really big difference in how your family handles whatever this fall brings.
Your Back-to-School Health Checklist
Before the first bell rings, here’s what we recommend you look into:
- Immunizations – Confirm that your child is up to date on all required school vaccines, or has an exemption on file.
- Sports physicals – If your child plays a school sport, make sure their physical exam is current before tryouts or practice starts.
- A plan for sick days – Decide your family’s stay-home thresholds now (such as fever, vomiting, or a bad cough) and line up backup childcare in advance. That way you’re checking a list at 6 a.m., and not making a judgement call while everyone’s rushing out the door.
- A well-child visit – If it’s been a year since your child’s last checkup, back-to-school season is a great time to get one on the calendar.
- Healthy habits at home – Handwashing, good sleep, and cleaning out that backpack are easy but effective ways to stay healthy during Minnesota cold and flu season.
Immunizations: What’s Required for Minnesota Schools
Minnesota’s school immunization law requires all students in kindergarten through 12th grade to show documentation of up-to-date immunizations, or file an exemption, before they can enroll or stay enrolled. According to the Minnesota Department of Health, students need documented doses of hepatitis B, polio, MMR, varicella, and DTaP by sixth grade, with a Tdap dose and meningococcal vaccine added for seventh grade and above.
Flu and COVID-19 vaccines aren’t required for school attendance, but they are recommended, especially as we head into a fall that has an early, active virus season already forecasted. If you’re not sure where your child stands, we’re happy to pull their record and let you know exactly what’s needed.
Sports Physicals: What Parents Need to Know
The Minnesota State High School League requires all students in grades 7 through 12 to complete a sports qualifying physical exam every three years in order to participate in school athletics. That said, the American Academy of Pediatrics recommends an annual physical exam for kids ages 3 to 18, and many providers (ourselves included) recommend a yearly checkup even in years that a sports physical technically isn’t required, especially if your child plays a sport year-round or has had any recent injuries.
A sports physical can often be combined with your child’s regular well-child visit, so it’s worth mentioning to our scheduling team when you book that you’ll need both taken care of at once.
When to Keep a Sick Kid Home
This is one of the questions that we hear the most from parents. As a general guideline, it’s best to keep your child home if they have:
- A fever of 100.4°F or higher (and for at least 24 hours after it resolves without fever-reducing medication)
- Vomiting or diarrhea within the past 24 hours
- A new or worsening cough with trouble breathing
- Pink eye with discharge, until it’s been evaluated or treated
- Symptoms severe enough that they can’t comfortably participate in class
A mild, lingering cough with no fever and normal energy generally doesn’t need to keep a child home. When in doubt, a quick call to our office can help you feel more confident making a decision.
Simple Habits That Help Kids Stay Healthier at School
- Wash hands often – Especially before eating and after recess or gym class.
- Clean what comes home in the backpack – Water bottles, phones, and Chromebooks can carry viruses for days.
- Prioritize sleep – A well-rested immune system handles classroom germs much better than an exhausted one.
- Don’t share drinks, utensils, or chapstick – This is a simple rule that cuts down on a lot of unnecessary exposure.
- Get the flu shot early – With an aggressive season forecasted, the early you get vaccinated, the better.

Frequently Asked Questions
How long is pink eye contagious, and when can my child return to school?
Most cases of pink eye in school-aged children are viral and are contagious for as long as the symptoms (like discharge or redness) are present. Bacterial pink eye is generally considered contagious until 24 hours after starting antibiotic treatment. When in doubt, it’s worth having it evaluated before sending your child back to class.
What’s the difference between RSV and a regular cold in kids?
In older kids and adults, RSV often looks just like a cold, with a runny nose, cough, and mild fever. In infants and toddlers, though, RSV can move into the lower airways and cause wheezing, rapid breathing, or trouble feeding, which is why it’s taken more seriously in very young children.
Do sports physicals expire, and how often does my child need one in Minnesota?
The Minnesota State High School League requires a sports qualifying physical exam every three years for students in grades 7 through 12. Many providers still recommend an annual well-child visit in between, especially for kids that play sports all year-round.
What vaccines does my child need to start school in Minnesota?
Minnesota law requires documented immunization against several diseases, including hepatitis B, polio, MMR, and varicella by sixth grade, with Tdap and meningococcal vaccines required starting in seventh grade, unless a medical or non-medical exemption is filed. Flu and COVID-19 vaccines are recommended but these are not required for school attendance.
Should I send my child to school with a runny nose but no fever?
Generally, yes. A mild runny nose or occasional cough with no fever and normal energy usually doesn’t warrant keeping a child home. It’s a different story if the cough is severe, they’re struggling to breathe, or they simply don’t feel well enough to participate in a normal school day.
