Disclosed is a novel means that enables complete cure of not only acute and chronic virus infections, but also latent retrovirus infections in which incorporation of the virus into the host chromosome has occurred. In the present invention, by destroying cells containing molecules that act as scaffolds for the virus infection in the patients body, cells per se that have been already infected with virus are destroyed while inhibiting expansion of the virus infection in the patients body, so that final complete cure of virus infection can be realized. The treatment of immunodeficiency virus infection may be carried out by administering an antibody or the like having high cytotoxic activity to the patient to destroy at least any of CD4 molecule-containing cells, CCR5 molecule-containing cells, and CXCR4 molecule-containing cells, preferably CD4 molecule-containing cells.
