As spring brings warmer weather, blooming flowers, and longer days, it also ushers in a spike of seasonal illnesses that commonly affect children. While the fresh air and outdoor play are welcome changes after winter, parents should remain alert to a range of health issues that tend to rise this time of year. Pediatricians across the country see predictable patterns in childhood illnesses during spring, from allergies to stomach bugs.

Here are the five most common springtime illnesses in children and how families can manage them effectively.

1. Seasonal Allergies

Pollen counts surge in the spring, making seasonal allergies the number one complaint among children during this time. Known medically as allergic rhinitis or hay fever, symptoms often mimic those of a cold: sneezing, runny nose, itchy eyes, and congestion.

“Allergies can really make kids miserable,” says Dr. Jennifer Holman, a pediatrician based in Tulsa. “We usually see the first wave of cases as early as March and they tend to peak in April and May.”

What parents can do:

• Keep windows closed on high pollen days.

• Encourage hand and face washing after outdoor play.

• Use over-the-counter antihistamines as directed by a pediatrician.

• Consult an allergist if symptoms are severe or persistent.

2. Common Cold

Although often associated with winter, colds are still prevalent in the spring, particularly when temperature swings are common. Cold viruses thrive in transitional weather, and the increased outdoor activity can lead to more contact with germs.

Unlike allergies, colds are caused by viral infections and can be spread through coughs, sneezes, or contact with contaminated surfaces.

Symptoms include:

• Sore throat

• Sneezing

• Cough

• Mild fever

• Runny or stuffy nose

How to treat it:
There is no cure for the common cold, but rest, fluids, and over-the-counter medications for symptoms can help. Encourage kids to cover their mouths when coughing and to wash hands regularly.

3. Stomach Bugs (Gastroenteritis)

Spring also brings an increase in cases of gastroenteritis, often referred to as the stomach flu. This viral illness can spread quickly in school and daycare environments, especially when children are sharing toys and snacks.

Symptoms include:

• Vomiting

• Diarrhea

• Stomach cramps

• Fever in some cases

“Gastroenteritis is highly contagious and can spread fast,” says Holman. “Dehydration is our biggest concern, especially in younger children.”

What to do:

• Keep your child hydrated with water, electrolyte solutions, or diluted juice.

• Avoid sugary or dairy-based drinks.

• Follow the BRAT diet (bananas, rice, applesauce, toast) once vomiting stops.

• Keep children home for at least 24 hours after symptoms resolve.

4. Strep Throat

Strep throat remains a common bacterial infection among children in spring, often confused with viral sore throats. It typically affects school-age children and spreads through direct contact with respiratory droplets.

Signs of strep throat:

• Sudden sore throat

• Painful swallowing

• Fever

• Swollen lymph nodes

• White patches on the tonsils

Unlike viral sore throats, strep throat requires antibiotics to treat. If left untreated, it can lead to complications like scarlet fever or rheumatic fever.

When to see a doctor:
If your child complains of a sore throat accompanied by a fever and swollen glands, it’s best to visit your pediatrician for a rapid strep test.

5. Pink Eye (Conjunctivitis)

Pink eye can be caused by viruses, bacteria, or allergens, making it a frequent visitor during spring months. It’s highly contagious and spreads quickly in classroom settings.

Symptoms of pink eye include:

• Red or pink discoloration in one or both eyes

• Itchy or gritty feeling

• Discharge, especially upon waking

• Excessive tearing

Treatment options:

• Viral pink eye usually resolves on its own.

• Bacterial pink eye may require antibiotic eye drops.

• Allergy-related pink eye can be managed with antihistamines and eye drops.

To prevent spread, teach kids not to touch their eyes and to wash their hands frequently.

Staying Ahead of Springtime Illnesses

While spring brings welcome relief from winter blues, it’s also a time when pediatric clinics see a spike in visits. The good news is that many of these illnesses are preventable or manageable with early action and healthy habits.

Here are a few general tips to keep your family healthier this season:

• Encourage frequent handwashing, especially before meals and after playing outside.

• Keep kids home when they’re sick to avoid spreading germs.

• Stay up to date on vaccinations and routine wellness checks.

• Teach children not to share personal items like water bottles, hats, or eye drops.

Springtime fun doesn’t have to be sidelined by sickness. With a bit of awareness and preparation, parents can help their children enjoy the season in good health.
