Disclosed is a use of homoharringtonine (HHT) in preparation of a drug against betacoronavirus infection, a use of homoharringtonine in preparation of a betacoronavirus replication inhibitor in human, and a formulation and a method for treating a disease caused by betacoronavirus. Through research, the HHT is found to not only have a good inhibitory effect on the first step of protein synthesis, but also have an unexpected inhibitory effect on each step of protein synthesis elongation, and can better inhibit the synthesis of long proteins. Because betacoronaviruses have longer ORFs and are more sensitive to the HHT, the HHT has a better replication inhibition effect on the betacoronaviruses, thus providing a feasible solution for controlling the replication of coronaviruses. The effects of the HHT on treating diseases caused by the betacoronaviruses including SARS-CoV-2 are confirmed for the first time by cell experiments and animal models.
