How Families Can Prepare for the Fall Illness Season

Fall brings more than cooler temperatures and changing leaves. As children return to school, families spend more time indoors, and respiratory viruses begin circulating, households can see an increase in colds, influenza, COVID-19, RSV, sore throats, ear infections, and other illnesses.

For the 2026–2027 respiratory illness season, the Centers for Disease Control and Prevention (CDC) expects influenza, COVID-19, and RSV to continue contributing to respiratory illness during the fall and winter months. Its current outlook anticipates a combined peak hospitalization burden similar to the previous season.

Preparing before illness spreads through the household does not guarantee that everyone will stay healthy. It can, however, make it easier to recognize symptoms, reduce transmission, and know when medical evaluation is appropriate.

Why Fall Can Mean More Illness at Home  

Fall changes how people interact.

Children return to classrooms. College students move into dormitories. Families spend more time indoors. Workplaces become more enclosed, and people have more opportunities for close contact.

Respiratory viruses can spread through these interactions.

The CDC identifies influenza, COVID-19, RSV, and other respiratory viruses as important causes of illness and recommends a combination of vaccination, hygiene, cleaner air, and staying home when sick to reduce risk.

1. Review Your Family's Recommended Vaccinations  

Vaccination should be part of a family's fall health preparation.

For the 2026–2027 flu season, CDC recommends annual influenza vaccination for everyone 6 months and older, with rare exceptions. For most people who require one dose, September and October are generally good times to receive the vaccine, ideally by the end of October.

The timing can differ for certain groups, including young children and older adults.

Families should also review whether household members are due for other recommended immunizations. CDC notes that recommendations may include vaccines for COVID-19, RSV, pneumococcal disease, shingles, or whooping cough depending on age and individual circumstances.

Vaccination decisions should be based on current recommendations and an individual's health circumstances.

2. Know What Symptoms to Watch For  

Not every fever, cough, or runny nose requires a medical visit.

Families should understand the symptoms that commonly accompany respiratory illnesses, including:

• Fever or chills

• Cough

• Sore throat

• Runny or stuffy nose

• Headache

• Fatigue

• Muscle or body aches

Some illnesses can also cause vomiting or diarrhea.

The CDC notes that influenza can occur without fever, so the absence of a fever does not necessarily rule out flu.

The more useful approach is to look at the overall pattern and severity of symptoms.

3. Keep Basic Supplies Available  

A well-prepared household does not need a large medical stockpile.

Consider having basic supplies available, such as:

• Thermometer

• Tissues

• Soap

• Alcohol-based hand sanitizer

• Appropriate over-the-counter medications

• Oral rehydration fluids when appropriate

• Cleaning supplies

For households with young children, older adults, or people with chronic medical conditions, it can also be useful to keep a current list of medications, allergies, and healthcare contacts readily available.

4. Make Hand Hygiene Routine  

Hand hygiene remains one of the simplest ways to reduce the spread of respiratory infections.

The CDC recommends regularly washing hands and using alcohol-based hand sanitizer when soap and water are unavailable. It also recommends covering coughs and sneezes and cleaning frequently touched surfaces.

Pay particular attention to handwashing:

• Before eating

• After coughing or sneezing

• After returning home

• After caring for someone who is sick

• After using the bathroom

• Before preparing food

These habits are especially important when multiple family members are sharing the same living space.

5. Pay Attention to Indoor Air  

Fall and winter often mean more time indoors.

Cleaner indoor air can be another layer of protection against respiratory viruses. The CDC recommends taking steps to improve indoor air quality where possible as part of its core respiratory-virus prevention strategies.

Depending on the setting, this may include:

• Increasing ventilation

• Bringing in outdoor air when practical

• Using appropriate air filtration

• Avoiding crowded, poorly ventilated spaces when illness is circulating

These measures do not replace vaccination or other preventive practices, but they can complement them.

6. Have a Plan for When Someone Gets Sick  

One of the most useful preparations is knowing what your family will do before someone develops symptoms.

If a household member develops a respiratory illness, consider:

• Limiting close contact with other household members when possible

• Improving ventilation

• Increasing hand hygiene

• Avoiding sharing personal items

• Monitoring symptoms

• Considering testing when appropriate

• Contacting a healthcare professional if symptoms are concerning

CDC guidance recommends that people with respiratory-virus symptoms stay home and away from others until, for at least 24 hours, their symptoms are improving overall and they have been free of fever without using fever-reducing medication. CDC then recommends additional precautions for the following five days when around others.

7. Know Which Family Members May Need Earlier Attention  

Respiratory illnesses can affect anyone, but the risk of serious illness is not the same for everyone.

CDC identifies groups at increased risk for serious influenza complications, including:

• Young children

• Adults 65 and older

• Pregnant people

• People with asthma

• People with diabetes

• People with certain heart or lung conditions

• People with weakened immune systems

Vaccination and early attention to symptoms can be particularly important for these groups.

If someone in your household is at higher risk, discuss in advance what symptoms should prompt a call to their healthcare professional.

8. Do Not Assume Every Sore Throat or Cough Needs Antibiotics  

Fall illnesses can create pressure to “treat” every symptom quickly.

But many common respiratory illnesses are viral.

Antibiotics work against certain bacterial infections and do not treat viruses such as influenza, COVID-19, or the common cold.

This distinction matters because unnecessary antibiotic use can expose patients to medication side effects and contributes to antimicrobial resistance.

A healthcare professional can determine whether symptoms suggest a condition that may require testing or specific treatment.

9. Recognize When a Child Needs Medical Evaluation  

Children can become sick quickly, and parents may find it difficult to determine whether symptoms are within the expected range.

Medical evaluation may be appropriate when a child has:

• Persistent or worsening fever

• Difficulty drinking

• Reduced urination

• Significant ear pain

• Severe sore throat

• Persistent vomiting

• Increasing breathing difficulty

• Symptoms that improve and then become significantly worse

• Unusual sleepiness or behavior changes

For infants, particularly very young infants, fever requires special attention because age significantly affects the level of concern.

10. Know the Emergency Warning Signs  

Some symptoms should not wait for an urgent care visit.

Seek emergency medical care for symptoms such as:

• Significant difficulty breathing

• Chest pain or pressure

• Blue, gray, or pale discoloration associated with breathing problems

• New confusion

• Severe difficulty staying awake

• Fainting

• Severe dehydration

• Seizures

• Other rapidly worsening or life-threatening symptoms

CDC respiratory-virus guidance specifically advises seeking emergency care for warning signs such as trouble breathing or chest pain.

What If Someone Gets Better and Then Gets Worse?  

This is a pattern families should pay attention to.

Someone may initially improve and then develop:

• Returning fever

• Increasing cough

• New shortness of breath

• Increasing facial or ear pain

• Worsening weakness

• New symptoms that were not present initially

A return of symptoms does not automatically mean a bacterial infection. However, a significant change after initial improvement can justify medical reassessment.

The CDC advises seeking medical care when respiratory symptoms improve but then return or worsen.

When Urgent Care Can Be Useful  

Urgent care can provide an intermediate option when a condition needs timely assessment but does not appear to be an emergency.

Depending on the facility and clinical situation, evaluation may include:

• Physical examination

• Vital signs

• Respiratory assessment

• Rapid influenza testing

• COVID-19 testing

• Strep testing

• Ear and throat examination

• Urinalysis

• Other testing when clinically indicated

The purpose is not simply to provide medication. It is to determine what is causing the symptoms and what level of care is appropriate.

Build a Simple Family Sick-Day Plan  

Before fall illnesses begin circulating, families can decide:

Who will stay home from school or work if sick?  

Who will care for a sick child?  

Which household members are at higher risk?  

Where are the thermometer and basic supplies kept?  

Which healthcare provider should be contacted?  

What symptoms would require urgent or emergency care?  

Having these decisions made in advance can reduce uncertainty when someone becomes ill.

Fall Preparation Is About More Than Avoiding Illness  

Good preparation is not about trying to eliminate every exposure.

It is about being ready to respond appropriately.

That means:

Prevent where possible.

Recognize symptoms early.

Reduce spread when someone becomes sick.

Know who may be at higher risk.

Seek medical care when symptoms warrant it.

Know the emergency warning signs.

The CDC describes vaccination, hygiene, cleaner air, and appropriate precautions when sick as complementary strategies for reducing respiratory illness risk.

The Bottom Line  

Fall illness season does not need to catch families unprepared.

Review recommended vaccinations, keep basic supplies available, practice good hygiene, pay attention to indoor air, and establish a plan for managing illness at home.

Most respiratory illnesses can be managed with supportive care, but symptoms that are severe, worsening, or returning after improvement may require professional evaluation.

The goal is not to treat every cough or fever as an emergency. It is to recognize when a routine illness may no longer be routine—and respond accordingly.
