Chronic Myelopathy Associated with Human T-Lymphotropic Virus Type I (HTLV-I)

TSP/HAM is a common neurologic disease in many parts of the world. All patients with chronic progressive myelopathies should be tested for serum and cerebrospinal fluid HTLV-I-specific antibodies. Systematic screening of blood donors for HTLV-I is necessary to help prevent the dissemination of the virus and the occurrence of post-transfusional cases.
