High Seasonal Burden of Influenza and RSV is Transforming the Respiratory Tract Infection Treatment Market in the US

The U.S. Respiratory Tract Infection Treatment Market is being transformed by the recurring seasonal burden of influenza and RSV, which increases demand for antivirals, monoclonal antibodies, hospital-based care, and outpatient prescriptions.

The CDC estimated that influenza and RSV together caused more than 1 million U.S. hospitalizations from October 2024 to September 2025. The RSV alone caused an estimated 190,000–350,000 hospitalizations and 10,000–23,000 deaths during October 2024–May 2025, thereby supporting the stronger use of preventive and treatment pathways.

In June 2025, the FDA approved the Enflonsia (clesrovimab-cfor), a long-acting monoclonal antibody for prevention of RSV lower respiratory tract disease in neonates and infants entering their first RSV season. This adds a new physician-administered product option and strengthens seasonal demand in pediatric respiratory infection management.

Long-acting RSV Monoclonal Antibodies: A Major Breakthrough in the Respiratory Tract Infection Treatment Market

Long-acting RSV monoclonal antibodies are becoming a major growth area in the Respiratory Tract Infection Treatment Market as they help prevent severe RSV disease before hospitalization is required. RSV continues to create a high treatment burden, as the CDC identifies RSV as the leading cause of hospitalization among U.S. infants.

The demand is gaining momentum because the preventive biologics minimize the need for intensive respiratory care during seasonal RSV outbreaks. In 2025, the CDC reported that nirsevimab was nearly 80% effective in preventing RSV-associated ICU admission and around 83% effective in preventing acute respiratory failure amongst the infants.

In July 2023, the FDA approved the Beyfortus (nirsevimab-alip) for preventing RSV lower respiratory tract disease in neonates, infants entering their first RSV season, and vulnerable children up to 24 months. This is strengthening the adoption of antibody-based prevention in the respiratory infection treatment pathways.

Why is Antibiotics Acquiring the Largest Share?

On the basis of drug class, the antibiotics segment is projected to account for the largest Respiratory Tract Infection Treatment Market share of 43.2% in 2026. The segment’s growth is owing to the high treatment need for bacterial pneumonia, sinusitis, bronchitis, and secondary bacterial infections after viral respiratory illness.

WHO reported that lower respiratory infections caused 2.5 million deaths in 2021, showing the high clinical burden requiring timely treatment. CDC also states that around 90% of human antibiotic use occurs in outpatient settings, where respiratory infections are among the most frequent reasons for prescriptions.

Recent approval activity further supports market growth. In April 2024, the U.S. FDA approved Zevtera, ceftobiprole medocaril sodium, for community-acquired bacterial pneumonia in adult and pediatric patients, adding a new antibiotic option for serious respiratory infections.

Upper Respiratory Tract Infection hold the Largest Market Share

To learn more about this report, Request Free Sample

On the basis of disease indication, the upper respiratory tract infection segment lead with a major 61.4% share in 2026. The segment’s growth is owing to the frequent cases of strep throat, sinusitis, pharyngitis, and viral upper respiratory infections that require physician visits, diagnostics, symptom-relief drugs, and selective antibiotic use.

CDC states that group A strep pharyngitis causes around 5.2 million outpatient visits annually among people below 65 years in the U.S., resulting in 2.8 million antibiotic prescriptions. CDC also reported that around 75% of sinusitis visits resulted in antibiotic prescribing, showing continued treatment volume for upper respiratory conditions.

A relevant development supporting respiratory infection management was the FDA’s July 2025 clearance of Roche’s cobas SARS-CoV-2, Influenza A/B, and RSV test, which aids differential diagnosis in patients with respiratory tract infection symptoms and supports more targeted treatment decisions.

Respiratory Tract Infection Treatment Market Trends

• Rising use of antibiotics, antivirals, NSAIDs, cough suppressants, and decongestants supports treatment demand across upper and lower respiratory infections.
• Growing preference for rapid diagnosis helps physicians differentiate viral and bacterial infections, improving targeted therapy and reducing misuse.
• Seasonal surges in influenza, RSV, pneumonia, and common cold cases increase prescription volumes through hospitals and retail pharmacies.
• Antimicrobial resistance is reshaping treatment decisions, encouraging safer prescribing and stronger demand for newer anti-infective therapies. At least 28% of outpatient antibiotics in the U.S. are considered unnecessary, showing the need for better treatment control.
• Rising RSV and pneumonia burden among infants and older adults is boosting demand for early treatment, supportive care, and preventive therapies. During 2024–25, RSV caused an estimated 190,000–350,000 hospitalizations in the U.S.
