Human T-lymphotropic virus. The human T-lymphotropic virus or human T-cell lymphotropic virus (HTLV) family of viruses are a group of human retroviruses that are known to cause a type of cancer called adult T-cell leukemia/lymphoma and a demyelinating disease called HTLV-I associated myelopathy/tropical spastic paraparesis (HAM/TSP).
They are only distantly related to the human immunodeficiency viruses (HIV-1 and HIV-2), which belong to the lentivirus subfamily of retroviruses and which cause acquired immunodeficiency syndrome (AIDS). Infections with HTLV-I and HTLV-II are most easily detected serologically.hey are different from the human immunodeficiency viruses that cause acquired immunodeficiency syndrome. Screening of the U.S. blood supply for HTLV-I/II, which began in 1988, identifies HTLV-I- and HTLV-II-infected persons who should be counseled regarding their infections.
