The COVID-19 pandemic continues to be a serious global health threat. Testing for the detection of SARS-CoV-2 will remain critical for managing the pandemic even during flu season. The severity of the 2021-22 flu season is uncertain as it converges with the COVID-19 pandemic.
The detection and differentiation of respiratory pathogens is important for managing patients with acute respiratory syndromes. This is even more critical during the flu season as seasonal viruses can be life-threatening, especially for hospitalized immunocompromised patients. SARS-CoV-2, Influenza A, Influenza B and Respiratory Syncytial Virus (RSV) have similar clinical presentations but require different treatment approaches. Therefore, early detection and differential diagnosis may be critical for optimal patient management.
