Is it fall allergies or is your child getting sick
9/18/2026
runny nose can all show up this fall. Here’s how to know what may be causing your child’s symptoms and how to prepare for the season ahead.
Fall brings cooler weather, school routines, outdoor activities, and unfortunately, plenty of sniffles.
For parents, one of the hardest parts is figuring out what those symptoms actually mean.
Is it seasonal allergies? A common cold? Flu? Something your child picked up at school?
While symptoms can overlap, there are a few clues that can help you decide what to do next.
Spring gets most of the attention when it comes to allergies, but fall can be difficult for children with seasonal allergies too.
Ragweed pollen is one of the major fall allergy triggers. Mold spores can also increase around damp leaves, soil, and other outdoor areas.
Children with fall allergies may experience:
→ Frequent sneezing
→ Clear or runny nose
→ Nasal congestion
→ Itchy or watery eyes
→ Itchy nose or throat
→ Postnasal drip
→ Mild coughing, especially from drainage
One useful clue is itchiness. An itchy nose, eyes, or throat is much more characteristic of allergies than many viral illnesses.
Allergy symptoms may also persist or return when your child is exposed to their triggers.
A runny nose alone doesn’t always give you the answer.
With seasonal allergies, children commonly have clear nasal drainage, sneezing, itchy or watery eyes, and symptoms that follow exposure to allergens. Allergies themselves do not cause fever and aren’t contagious.
A viral respiratory infection may include congestion and coughing too, but your child may also develop fever, sore throat, fatigue, decreased appetite, or symptoms that change over several days.
And once school is back in session, children have plenty of opportunities to encounter respiratory viruses.
If you’re unsure which one you’re dealing with, especially when symptoms are worsening rather than improving, an evaluation can help.
Flu can look very different from a typical case of seasonal allergies.
Children with influenza may develop symptoms such as:
→ Fever or chills
→ Cough
→ Sore throat
→ Runny or stuffy nose
→ Headache or body aches
→ Significant tiredness
→ Vomiting or diarrhea, which can occur more commonly in children than adults
Unlike seasonal allergies, flu is caused by a virus and can spread from person to person.
That makes fall a good time to think beyond treating today’s sniffles and start preparing your family for the respiratory illness season ahead.
Fall also means the start of another flu season, making this a good time to check whether your family is up to date on recommended vaccinations.
The CDC recommends annual flu vaccination for most people ages 6 months and older. Staying current on recommended vaccines can help protect your family as respiratory illnesses begin circulating more frequently during the fall and winter months.
Night Watch Urgent Care offers routine and seasonal vaccinations, making it easier to take care of this important fall health task.
Vaccine availability may vary, so call your nearest Night Watch location to confirm which vaccines are currently available before your visit.
If allergies are the problem, reducing exposure can sometimes make the season more comfortable.
Try having children wash their hands and face after spending time outside, change clothes after heavy outdoor exposure, keep windows closed when pollen counts are high, and avoid letting piles of damp leaves accumulate around areas where children play.
Your child’s healthcare provider can also help you determine whether an age-appropriate allergy treatment may be useful.
Not every sniffle needs an urgent care visit. But it may be time for an evaluation if you’re unsure whether symptoms are allergies or an illness, symptoms continue to worsen, your child develops a persistent or high fever, they’re having difficulty eating or drinking, or they’re simply not acting like themselves.
Seek emergency care for significant difficulty breathing, blue or gray lips or skin, severe dehydration, or if your child is extremely difficult to wake.
Whether it’s a cough that appeared overnight, a fever after school, worsening allergy symptoms, or you’re simply unsure what’s making your child sick, Night Watch Urgent Care is here to help.
