RIVERA-CALDON, Cristhian Camilo et al. Human T-lymphotropic virus type 1 (HTLV-1) infection and spastic paraparesis. Advances and diagnosis 35 years after its Discovery. Iatreia [online]. 2017, vol.30, n.2, pp.146-159. ISSN 0121-0793.  https://doi.org/10.17533/udea.iatreia.v30n2a04.

Human T-lymphotropic virus type 1 (HTLV-1) causes disorders such as chronic inflammatory progressive myelopathy, which is known as HTLV-1associated myelopathy (MAH), characterized by spastic paraparesis symptoms. Originally, the virus was reported in tropical zones and is currently distributed in different regions of the world. HTLV-1 can be transmitted both horizontally and vertically, and remains latent in patients; between 1 % and 5 % of those infected develop adult T cell leukemia/lymphoma (LTA) and 3 % to 5 %, MAH. This review, carried out through systematic search of databases, compiles the most outstanding information about this retrovirus and the spastic paraparesis, provides basic knowledge on the disease, illustrates on an unknown health problem and creates the need for early diagnosis in order to stop the chain of viral infection and prevent its silent propagation among the population.

Palavras-chave : HTLV-1; MAH; Retrovirus; Spastic Paraparesis.
