    Abstract: The present disclosure relates to a method for preventing and treating or diagnosing coronavirus infection. SARS-CoV2 lung infection animal models are established using rhesus macaques and human ACE2 transgenic mice, innate immune characteristics that occur in the body in the early stage of SARS-CoV2 infection are explored, and S100A8 protein is found as the root cause initiating the inflammatory storm and becomes an immune indicator for early diagnosis of a patient with SARS-CoV2 infection. Then inhibition of the function of S100A8/S100A9 dimer finally inhibits the virus titer in tissues, thereby decreasing the inflammation level, which proves that a dimer inhibitor can be used as an effective drug for preventing and treating coronavirus infection.
