With the global outbreak of the coronavirus disease 2019 (COVID-19), the highly infective, highly pathogenic, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has attracted great attention. Currently, a method to simultaneously diagnose the seven known types human coronaviruses remains lacking and is urgently needed. In this work, we successfully developed a portable microfluidic system for the rapid, accurate, and simultaneous detection of SARS-CoV, middle east respiratory syndrome coronavirus (MERS-CoV), SARS-CoV-2, and four other human coronaviruses (HCoVs) including HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1. The disk-like microfluidic platform integrated with loop-mediated isothermal amplification provides highly accurate, sensitive, and specific results with a wide linear range within 40 min. The diagnostic tool achieved 100% consistency with the "gold standard" polymerase chain reaction in detecting 54 real clinical samples. The integrated system, with its simplicity, is urgently needed for the diagnosis of SARS-CoV-2 during the COVID-19 pandemic.
