Navigating the 2025-2026 Respiratory Virus Season: Global Trends

Navigating the 2025-2026 Respiratory Virus Season: Global Trends, Key Viruses, and Protection Tips – February 2026 Update

Introduction

Respiratory viruses remain a major concern worldwide, especially in the northern hemisphere's winter months. As of early February 2026, the 2025-2026 season is active but moderate in many regions, with acute respiratory illness levels dropping to moderate nationally in places like the US after holiday peaks. Influenza activity has decreased or stabilized in recent weeks but remains elevated, RSV is still high in spots (particularly affecting children and older adults), and COVID-19 is generally stable or low with some localized upticks. Globally (per WHO data through late January 2026), influenza positivity sits around 15%, down from earlier highs but still circulating strongly in temperate and subtropical areas.

This season's combined burden from flu, RSV, and COVID-19 is expected to be similar to last year's, though staggered peaks have eased pressure on healthcare systems compared to past "tripledemics.

The Main Human Respiratory Viruses in Play

Influenza (Flu) – Dominant but Trending Downward

Influenza A (especially H3N2 subclade K strains) has driven much of the season's surge, with high hospitalization rates in some groups like children. Activity remains elevated nationally in the US and northern hemisphere, but recent weeks show decreases or stability after three weeks of declines in key indicators. Positivity hovers around 15-18% in surveillance. Vaccines provide good protection against severe outcomes despite some mismatch with emerging strains.

Respiratory Syncytial Virus (RSV) – Elevated, Especially in Vulnerable Groups

RSV continues elevated in many areas, contributing to hospitalizations in infants, young children, and older adults. Positivity exceeds 5% in some reports, with upward trends from fall into winter. Vaccines and monoclonal antibodies offer strong protection for high-risk groups.

SARS-CoV-2 (COVID-19) – Stable and Low Overall

COVID-19 activity is moderate in pockets but generally low/stable nationally and globally. Hospitalizations are decreasing in many places, with wastewater signals showing no major surges yet. Updated vaccines continue to reduce severe illness risk.

Rhinoviruses, Common Coronaviruses, and Others

Rhinoviruses lead as the top cause of common colds year-round, often mild. Seasonal coronaviruses (non-SARS), human metapneumovirus (hMPV), parainfluenza, and adenoviruses add to upper respiratory cases, with occasional lower respiratory complications in vulnerable people. Emerging animal-origin viruses like influenza D or canine coronavirus are under monitoring but not yet major human threats.

Global Trends Right Now (Early February 2026)

Northern Hemisphere: Influenza and RSV elevated but declining in many indicators; acute respiratory illness moderate. Flu hospitalizations peaked high earlier but are trending down.

US (CDC data through late January): Moderate acute illness seeking care; flu elevated but decreasing; RSV elevated; COVID-19 moderate in some areas.

Global (WHO): Influenza positivity ~15% (down but elevated); SARS-CoV-2 stable/low; RSV variable but contributing.

The season typically extends into spring, so vigilance remains key.

Recognizing the Symptoms – Know When to Act

Symptoms often overlap, so testing helps identify the cause:

Common across viruses: Runny/stuffy nose, sore throat, cough, fatigue, headache, fever/chills, body aches.

Flu: Sudden onset, high fever, severe muscle aches, extreme tiredness.

RSV: Wheezing, rapid breathing, more lower respiratory focus (especially in kids).

COVID-19: Possible loss of taste/smell (less common now), prolonged fatigue.

Common cold: Gradual, milder, mostly nasal.

Seek medical help promptly for shortness of breath, persistent high fever, chest pain, confusion, or worsening symptoms—especially in high-risk groups (elderly, young children, pregnant individuals, those with chronic conditions).

Prevention Strategies That Work Worldwide
Vaccination is your strongest tool:

Annual flu vaccine: Updated strains; still effective against severe disease.

COVID-19 updated vaccines: Recommended to lower severe outcomes.

RSV vaccines/antibodies: For adults 60+, pregnant people, and high-risk infants.

Additional everyday measures:

Wash hands often with soap/water or use sanitizer.

Cover coughs/sneezes with elbow or tissue.

Stay home when sick to limit spread.

Improve ventilation indoors; consider air purifiers.

Wear masks in crowded indoor spaces during peaks.

Maintain healthy habits: good sleep, nutrition, and exercise to support immunity.

Final Thoughts

Stay Vigilant and Healthy

The 2025-2026 respiratory season is proving manageable but active—knowledge and proactive steps make all the difference. As February progresses, keep up with local updates, get vaccinated if eligible, and prioritize hygiene. For personalized advice, consult your healthcare provider or pharmacist.
