Influenza is a zoonotic disease, infecting a wide variety of warm-blooded animals. It is caused by an influenza virus, which has been found with hundreds of subtypes. These subtypes are often associated with different sources of infection and possess complex courses of infection. In the early stage of influenza infection, rapid subtype detection is very practicable to prevent the disease from getting worse. Herein, we presented a high-throughput microfluidic centrifugal disc for rapid detection of influenza virus subtypes. The disc realized detection reagent preloads, automated reagent control, and RT-LAMP detections. Six kinds of highly pathogenic influenza viruses could be simultaneously identified, including influenza A subtypes H1, H3, H5, H7, and H9 and influenza B virus. Two different fluorescent dyes could be used on the disc for real-time detection or read by the naked eye. The performance of the disc was demonstrated by testing the clinical samples. The integrated centrifugal disc was expected for rapid detection of influenza virus subtypes to facilitate accurate drug usage in resource-constrained settings and contribute to reduce the risk of the influenza pandemic.
