Respiratory Virus Season 2025–2026: What to Know About Flu, COVID-19, and RSV Right Now

As the 2025–2026 respiratory virus season continues across the United States, flu, COVID-19, and RSV (respiratory syncytial virus) are still sending people to clinics and hospitals.

The practical takeaway: If you or a family member is at higher risk for severe illness, staying up to date on recommended vaccines, recognizing symptoms early, and knowing when to seek care can make a meaningful difference.

What’s Circulating This Season

According to the Centers for Disease Control and Prevention (CDC), influenza, COVID-19, and RSV remain the primary respiratory viruses of concern during the fall and winter months. These viruses often peak at different times, and activity can vary by region.

While most healthy adults recover at home, older adults, infants, pregnant people, and individuals with chronic conditions—such as heart disease, lung disease, diabetes, or weakened immune systems—face a higher risk of hospitalization.

Symptoms to Watch For

Flu, COVID-19, and RSV share many overlapping symptoms, including:

Fever or chills
Cough
Sore throat
Runny or stuffy nose
Fatigue
Headache or body aches

COVID-19 may also cause loss of taste or smell, though this is less common with newer variants than earlier in the pandemic. RSV in infants can present with wheezing, fast breathing, or difficulty feeding.

Because symptoms overlap, testing may be needed—especially for people at higher risk or those who may qualify for antiviral treatment.

Vaccines: Who Should Consider Them

The CDC recommends annual flu vaccination for everyone 6 months and older, unless there is a medical reason not to receive it. Updated COVID-19 vaccines are also recommended for most age groups, particularly older adults and people with underlying health conditions.

For RSV, prevention options now include:

An RSV vaccine for adults ages 60 and older, based on shared clinical decision-making.
An RSV vaccine for pregnant people to help protect newborns.
A long-acting monoclonal antibody injection for certain infants entering their first RSV season.

These recommendations are based on large randomized clinical trials reviewed by the CDC and the Food and Drug Administration (FDA). Trials showed that vaccines reduced the risk of severe disease and hospitalization. However, protection can decrease over time, and vaccines do not eliminate all risk.

Antiviral Treatment: Timing Matters

For influenza and COVID-19, prescription antiviral medications are available. These treatments work best when started early—usually within the first few days of symptoms.

People who are older, immunocompromised, pregnant, or living with chronic conditions should contact a healthcare professional promptly if they test positive or develop symptoms. Early treatment can lower the risk of severe illness and hospitalization.

Who Is at Higher Risk?

Based on CDC guidance, groups at higher risk for complications include:

Adults age 65 and older
Children under age 5, especially infants
Pregnant and recently pregnant individuals
People with chronic medical conditions
Residents of nursing homes or long-term care facilities

Caregivers and family members of high-risk individuals should also take preventive steps, including vaccination and staying home when sick.

When to Seek Medical Care

Seek urgent medical attention if you or a loved one experiences:

Difficulty breathing
Chest pain or pressure
Confusion
Signs of dehydration (such as very little urine or dizziness)
In infants: fast breathing, bluish lips, or trouble feeding

Even milder cases can warrant a call to a clinician if the person is in a high-risk group.

Prevention Beyond Vaccines

In addition to vaccination, public health agencies recommend:

Staying home when sick
Washing hands regularly
Improving indoor ventilation when possible
Wearing a well-fitting mask in high-risk settings, especially during periods of high local transmission

Workplaces and schools can reduce spread by encouraging sick leave flexibility and improving air quality. These steps help protect vulnerable individuals and reduce strain on local healthcare systems.

What About Oral Health?

Respiratory viruses primarily affect the lungs and airways, but overall health—including oral health—can influence recovery. Gum disease and untreated dental infections can contribute to systemic inflammation. Maintaining routine dental care and managing chronic conditions supports overall resilience during respiratory virus season.

What This Means for You

Respiratory virus season is not new, but each year brings a different mix of timing and intensity. The core strategies remain consistent: stay up to date on recommended vaccines, test early if symptoms develop, seek treatment promptly if you are at higher risk, and take practical steps to reduce spread.

For families, this means checking vaccination status, having a plan for testing and sick leave, and knowing who in your household may need extra protection.
