Spring Allergies Are Here: New CDC Data Show How Common They Are, and Why Early Treatment Matters

Seasonal allergies are not a small, occasional problem. New CDC data released in January 2026 show that in 2024, about 1 in 4 U.S. adults and 1 in 5 children had a diagnosed seasonal allergy. That makes spring sneezing, congestion, and itchy eyes a major everyday health issue for families, schools, and workplaces.

For adults, the National Center for Health Statistics found that 25.2% had a diagnosed seasonal allergy in 2024. For children, the estimate was 20.6%. The same CDC reports also found that children ages 6 to 11 and 12 to 17 were more likely to have seasonal allergies than children ages 0 to 5, which helps explain why school-age kids often seem to struggle more once pollen season ramps up.

The practical takeaway is simple: if you get the same spring symptoms year after year, it is worth recognizing them early and treating them appropriately. Waiting too long can mean worse sleep, harder school days, more missed work, and, for some people, more breathing trouble.

What spring allergies usually feel like

Seasonal allergies, often called allergic rhinitis or hay fever, usually cause a clear runny nose, sneezing, stuffiness, postnasal drip, and itching of the eyes, nose, or throat. A 2024 review in JAMA described nasal congestion and runny nose as especially common symptoms, along with sneezing and itching.

That symptom pattern can overlap with a cold, which is why many people are unsure what they are dealing with at first. One plain-language clue is itching: itchy eyes and an itchy nose are more typical of allergies than of a routine viral infection. Fever, body aches, and a general sick feeling point more toward a cold or another infection than toward seasonal allergies.

Timing also matters. If symptoms appear quickly when pollen is high, or if they show up around the same weeks every spring, allergies move higher on the list. But not every sneeze or stuffy nose is allergy. If symptoms are severe, unusual, or prolonged, a clinician can help sort out whether you are dealing with allergies, a virus, sinus disease, asthma, or another problem.

Why antibiotics are the wrong treatment

The CDC is very clear on this point: antibiotics do not work for seasonal allergies. Allergies are not caused by bacteria, so antibiotics do not treat the underlying problem.

That matters because many people reach for antibiotics when congestion drags on or sinus pressure develops. But using antibiotics when they are not needed exposes people to possible side effects without helping the allergy symptoms. Antibiotics should only be used if a clinician diagnoses a bacterial infection that actually calls for them.

If your main symptoms are sneezing, itchy or watery eyes, clear runny nose, and congestion during pollen season, think allergies first, not antibiotics.

Why people with asthma should pay extra attention

Pollen does not just irritate the nose and eyes. It can also aggravate asthma. A recent New York City health advisory warned that spring tree pollen can worsen asthma and allergic eye-and-nose symptoms, and that asthma emergency visits, especially in children, often rise during peak spring pollen periods. That is local public health data, not a national count, but it is a useful reminder that pollen season can become a breathing issue, not just a nuisance.

This is especially important for people who already have asthma, children who wheeze, and caregivers trying to keep kids stable during the school day. If pollen tends to trigger cough, chest tightness, wheezing, or shortness of breath, it is smart to review an asthma action plan before symptoms spike. Do not wait until breathing gets worse.

There is also a broader community angle. The Asthma and Allergy Foundation of America noted in its 2026 Allergy Capitals report that some metro areas face a heavier pollen burden along with fewer allergy specialists. That report is not a national prevalence study, but it helps explain why allergy season can feel harder to manage in some places than others.

What helps most at home

The best first step is reducing pollen exposure as much as you reasonably can. You do not have to stay indoors all spring, but a few habits can make a real difference.

Keep home and car windows closed on high-pollen days.
Shower and change clothes after spending time outdoors.
Wash pollen out of your hair before bed if possible.
Use a saline spray or a properly prepared saline rinse to help flush allergens from the nose.
Consider glasses or sunglasses outside if your eyes are a major problem.

Medication can help too. According to the JAMA review, first-line treatment for mild intermittent or mild persistent allergic rhinitis can include a second-generation oral antihistamine. In plain language, that means the newer, less-drowsy allergy pills many people already know, such as loratadine or fexofenadine, may help with sneezing, itching, and a runny nose.

For people whose biggest problem is nasal congestion and ongoing inflammation, intranasal steroid sprays are a key option. MedlinePlus and the JAMA review both describe nasal corticosteroid sprays as among the most effective treatments for allergic rhinitis. These sprays tend to work best when used regularly, not just once in a while when symptoms are already severe.

That is one reason early treatment matters. If you usually get hit hard every April or May, starting the right medicine before symptoms fully build can make the season easier to manage.

It is also worth setting expectations. These medicines can control symptoms, but they are not cures. Some people will still need a clinician visit, prescription treatment, or allergy testing to get better control.

When it is time to see a clinician

Self-care is reasonable for mild, familiar spring allergy symptoms. But it is time to get medical advice if:

You have wheezing, shortness of breath, chest tightness, or breathing trouble.
Your symptoms are not improving with over-the-counter treatment.
Your symptoms keep coming back and you are not sure whether this is allergy, asthma, a cold, or sinus disease.
You have recurrent sinus symptoms or symptoms that seem more severe than your usual pattern.
Your sleep, school performance, work, or daily functioning is taking a real hit.
Treatment that used to work no longer works well.

A clinician may suggest a different treatment approach, check whether asthma is part of the picture, or discuss allergy testing. That can be especially helpful when symptoms are strong, persistent, or confusing.

What this means for readers

The new CDC numbers are a reminder that spring allergies are common in both adults and children, not a minor issue that people should just push through. The right response is not antibiotics. It is recognizing the pattern, reducing pollen exposure, and using evidence-based treatments such as saline, less-drowsy antihistamines, and nasal steroid sprays when they fit your symptoms.

And if pollen season affects your breathing, your child’s asthma, your sleep, or your ability to get through the day, do not write it off as “just allergies.” That is a good reason to get care.
