Common Winter Illnesses in Kids

Winter brings a familiar but stressful reality for many parents: cold weather, holiday travel, and a higher risk of sickness. As pediatricians at Entirely Kids Pediatrics in Frisco, we see many children with symptoms of common winter illnesses, and it’s natural for parents to wonder when a sniffle is harmless — and when it’s time to call for a same day sick visit.

In this guide, we’ll cover the illnesses that tend to surge in the colder months (like RSV, strep throat, and flu), how to recognize concerning symptoms, and why our same day sick visits in Frisco matter. Our goal is to help you feel confident deciding when to bring your child in for prompt pediatric care.

Why Winter Increases the Risk of Childhood Illness?

Several factors make winter a challenging season for children’s health:

Indoor Crowding: Cold weather means more time spent inside, increasing the chance of virus spread among siblings, classmates, or during holiday gatherings.
Dry Air: Heated indoor spaces often have low humidity. Dryer air can irritate the respiratory tract, making it easier for viruses to take hold.
Travel: Holiday travel brings exposure to new environments and germs — plus disrupted routines, which lower resistance.
Rapid Onset of Symptoms: Children are often exposed to several viruses in a row, and symptoms can escalate quickly.

For these reasons, having access to prompt pediatric urgent care in Frisco can make a big difference in outcome and peace of mind.

Here are some of the most frequent winter illnesses we see in Frisco, how they present, and when same-day care may be needed:

1. Respiratory Syncytial Virus (RSV)

What It Is: RSV is a common virus that causes mild, cold-like symptoms in older children, but can lead to serious respiratory problems in infants.
Symptoms: Runny nose, reduced appetite, coughing, wheezing, rapid or difficult breathing.
When to Call: If your baby or child has trouble breathing, is feeding poorly, or shows signs of dehydration, you should call for a same-day visit. Young infants, especially under 12 months, may need more frequent monitoring.

2. Strep Throat

What It Is: A bacterial infection often caused by Streptococcus pyogenes.
Symptoms: Sudden sore throat, fever, red/swollen tonsils (sometimes with white patches), headache, stomach ache (especially in younger kids), swollen lymph nodes.
When to Call: If your child has a sore throat with fever lasting more than 24 hours, difficulty swallowing, or if you know they were exposed to strep. A pediatrician can do a rapid strep test and begin treatment if needed.

3. Influenza (Flu)

What It Is: The flu is a contagious respiratory illness caused by influenza viruses.
Symptoms: Fever, chills, body ache, cough, fatigue, headaches — sometimes gastrointestinal symptoms in children.
When to Call: For high, persistent fevers, breathing trouble, worsening symptoms after a few days, or if your child is in a risk group (very young, chronic illness, etc.). Early intervention can reduce risk of complications.

4. Common Cold and Viral Upper Respiratory Infections

What It Is: Caused by many types of viruses.
Symptoms: Runny or stuffy nose, sneezing, mild cough, mild fatigue, low-grade fever.
When to Call: If your child’s symptoms worsen, they are unusually lethargic, or they develop new symptoms like ear pain, rash, or trouble breathing, it’s worth scheduling a same-day visit.

5. Ear Infections

What It Is: Often a complication of a cold or viral infection.
Symptoms: Tugging or rubbing the ear, fussiness, fever, fluid draining from ear.
When to Call: If your child has persistent ear pain, fever, or changes in hearing or behavior. Our pediatric team can evaluate and treat appropriately.

Why Same-Day Sick Visits Make Sense for Winter Illnesses?

At Entirely Kids Pediatrics, we reserve slots every day for same-day sick visits so that children don’t have to wait in urgent care or emergency rooms for non-emergency illnesses. Here’s why that matters:

Prompt Diagnosis and Treatment: Early evaluation helps us decide if an illness is viral (like RSV) or bacterial (like strep), and start treatment quickly when needed.
Comfort of Pediatric Specialists: Your child will be treated by a doctor who specializes in children — not by general urgent care or ER staff unfamiliar with pediatric needs.
Reduced ER Visits: When you use same-day care, you avoid long ER waits, exposure to other sick patients, and higher costs.
Tailored Care: We tailor care to your child’s age, weight, and symptoms — from infants with RSV to school-age children with sore throats.

Red Flags: When You Should Not Wait

Some symptoms should never wait for the next day. Call for same-day care or emergency care if you see:

Severe difficulty breathing, rapid or shallow breathing, or wheezing
Lips or nails that turn blue or purple
High fever not improving, especially in infants
Signs of dehydration (no wet diapers, dry mouth)
Confusion, lethargy, or significant behavioral changes
Unusual rash with fever
Persistent vomiting or poor feeding

These could indicate serious viral or bacterial illness needing prompt evaluation.

What to Expect During a Same-Day Sick Visit with Us?

When you call Entirely Kids Pediatrics for a same-day sick visit in Frisco, here’s how our process helps you and your child:

Call ASAP: Contact our office at the first sign of concerning symptoms.
Symptom Triage: Our staff will ask a few questions about your child’s symptoms to help us estimate how urgent the visit is.
On-the-Day Care: We reserve daily spots for same-day visits, so your child can be seen by a trusted pediatrician when they need care most.
Focused Exam and Testing: During the visit, we’ll examine your child, possibly perform a rapid strep test, or evaluate for RSV or other conditions, tailored to their presentation.
Clear Communication: We explain findings, suggest home care if appropriate, and give you a clear plan — whether that’s treatment, monitoring, or follow-up.
Parental Support: We take time to answer your questions, suggest symptom relief, and let you know when things should improve or when to return.

Preparing for a Sick Visit During Cold Season

To make the most of a same-day visit, parents can:

Write down your child’s symptoms and when they began
Take note of fever patterns, cough severity, breathing changes
Bring any recent medications and your child’s medical history
Be ready to share what you’ve tried at home (fluids, fever reducers, etc.)
Know your child’s insurance and any relevant forms

Being prepared helps us spend more time diagnosing and fewer minutes gathering information.

Preventive Habits to Reduce Winter Illness

While same-day care is invaluable, prevention remains the front line:

Encourage regular hand hygiene and teach children to wash thoroughly.
Maintain a routine that supports immunity: good sleep, healthy eating, and stress management.
Keep up with well-child visits and immunizations (especially flu shots) to help your pediatrician track growth and risk. Limit exposure when possible — for example, minimize close contact during peak sick season or holiday travel.
Clean and sanitize shared surfaces after family gatherings.
