Human T-lymphotropic virus
Human T-Lymphotropic virus (HTLV) is a retrovirus that primarily infects T lymphocytes, which are white blood cells important in the immune system. It is spread through contact with infected body fluids, such as semen, blood, or breast milk. HTLV can cause serious health problems like cancers, such as adult T-cell leukemia and lymphoma. HTLV is also associated with some neurologic disorders such as HTLV-1 �associated myelopathy.
