Between school, daycare, sports, and family gatherings, fall schedules fill up quickly. Preparing for flu season gives San Antonio families one less thing to figure out when a child wakes up feeling sick.
Start with three priorities: plan flu vaccinations, practice everyday prevention, and know when to call for care. A few steps now can make it easier to respond calmly later.
An annual flu vaccine is the most important step families can take to reduce the risk of flu and serious complications. CDC recommends seasonal flu vaccination for everyone age 6 months and older, with rare exceptions. Babies younger than 6 months cannot receive a flu vaccine, making vaccination of eligible caregivers especially important. CDC flu prevention guidance
For the 2026–2027 flu season, keep these timing reminders in mind:
● September and October are generally ideal for most people who need one dose.
● Some children ages 6 months through 8 years need two doses, depending on previous flu vaccinations. Those doses must be at least four weeks apart.
● Children who need two doses should start as soon as the seasonal vaccine is available, ideally completing both doses by the end of October.
● Missing October does not mean it is too late. Vaccination can continue while flu viruses are circulating and vaccine remains available.
Your child’s provider can review vaccination records and recommend an appropriate vaccine and schedule. CDC 2026–2027 influenza vaccine guidance
Flu prevention works best when the whole household participates. Make these habits part of school mornings, meals, and after-school routines:
● Wash hands regularly, especially before eating and after coughing, sneezing, or blowing the nose.
● Cover coughs and sneezes with a tissue or elbow.
● Improve indoor air by bringing in fresh air when practical, using air filtration, or gathering outdoors when conditions allow.
● Clean frequently touched surfaces, including doorknobs, counters, and shared devices.
● Limit close contact with people who are sick and keep children home when illness begins.
These steps complement vaccination and help reduce the spread of respiratory illnesses. CDC healthy habits to prevent flu
Preparation does not need to be complicated. Before someone gets sick:
● Save the clinic’s phone number and ask how to get guidance after hours.
● Keep vaccination records, medication lists, and allergy information together.
● Check that you have a working thermometer.
● Review your school or daycare’s illness and return policies.
● Plan who can pick up or stay home with a sick child.
● If your child has asthma or another ongoing condition, review their care plan and prescribed medications with their provider.
Share the plan with grandparents, babysitters, and other caregivers so everyone knows whom to call and where to find important information.
Flu symptoms often begin suddenly. Children may develop fever or chills, cough, sore throat, a stuffy or runny nose, body aches, headache, and unusual tiredness. Vomiting or diarrhea can also occur. A child can have flu without a fever. CDC flu symptoms
When symptoms start, keep a short record of:
● When your child first felt sick.
● Temperature readings and how they were taken.
● How much your child is drinking and how often they urinate.
● Changes in breathing, alertness, or activity.
● Medication names, doses, and times given.
● Known exposures and whether symptoms are improving or worsening.

Contact your child’s provider promptly if you suspect flu, especially if your child is younger than 5—particularly younger than 2—or has asthma, diabetes, heart or lung disease, or another condition that increases complication risk.
Prescription antiviral treatment works best when started within the first two days of symptoms. Treatment may still help later, particularly for children with severe illness or higher risk, so do not assume you have missed the opportunity to seek care. Your provider can decide whether treatment is appropriate. CDC guidance on treating flu in children
When calling Pediatric Heroes, describe your child’s age, symptoms, and when the illness began. Ask whether your child needs an evaluation and how soon they should be seen.
Do not wait for a routine appointment if your child has:
● Difficult or unusually fast breathing, ribs pulling inward, or blue lips or face.
● Chest pain, a seizure, or difficulty waking or interacting.
● Dehydration, such as no urine for eight hours, a very dry mouth, or no tears.
● Severe muscle pain that makes them refuse to walk.
● Fever above 104°F that fever-reducing medicine does not control.
● Any fever in a baby younger than 12 weeks.
● Fever or cough that improves and then returns or worsens.
Seek medical care right away for these warning signs. Call 911 for life-threatening symptoms, including severe breathing difficulty, blue lips, or unresponsiveness. CDC emergency warning signs
Not every cough or fever requires testing. A provider considers your child’s symptoms, health history, examination, and illness timing when deciding whether a test would help guide care.
Pediatric Heroes and Families Primary Care Clinic offers preventive care, care for acute symptoms, and in-house diagnostic testing, including flu testing when appropriate. A sick visit gives families an opportunity to discuss next steps and what changes to watch for at home.
CDC advises staying home until, for at least 24 hours, symptoms have been improving overall and there has been no fever without fever-reducing medication.
For the next five days, use added precautions such as cleaner air, good hygiene, and distancing from vulnerable people when possible. Also follow your school or daycare’s return requirements and your provider’s advice. If fever returns or symptoms worsen, stay home again. CDC guidance for respiratory illness recovery

Ask before fall schedules get busy. September and October are generally ideal for people who need one dose. Children who need two doses should begin earlier when vaccine is available to allow at least four weeks between doses. Your provider can confirm your child’s schedule using current CDC guidance.
No. Testing depends on whether the result would help guide care. Your provider will consider symptoms, timing, health history, and examination findings.
Record when symptoms began, temperature readings, fluid intake, urination, breathing changes, and medications given. Include known exposures and whether your child is getting better or worse.
Yes, especially if your child is at higher risk or has worsening symptoms. Although antivirals work best early, some children can benefit when treatment starts later. CDC flu treatment guidance
