Respiratory viral infections represent a major public health concern due to their high transmissibility and significant clinical impact. They affect all populations, with increased risks in the elderly, children, immunocompromised patients, and individuals with underlying comorbidities. They are characterized by recurring seasonal epidemics and pandemics with considerable health and economic consequences. The diversity of the viruses involved and their capacity to evolve complicate both surveillance and clinical management.

Main Respiratory Viruses

• Influenza A and B viruses: responsible for seasonal influenza, which can lead to severe complications such as pneumonia or cardiac decompensation.
• SARS-CoV-2: the causative agent of the COVID-19 pandemic, highlighting the importance of screening and infection control strategies.
• Respiratory Syncytial Virus (RSV): the leading cause of hospitalization for bronchiolitis in infants and adults over 65 years old.
• Human metapneumovirus: involved in severe respiratory infections, often underestimated.
• Rhinoviruses and enteroviruses: frequently responsible for common colds and asthma exacerbations.
• Adenoviruses and bocaviruses: often detected in severe respiratory infections in children.

With the regular emergence of new respiratory pathogens, there is an urgent need for solutions capable of rapidly adapting to emerging threats while enabling the detection of multiple pathogens in a single test.
