  • Title: Molecular evidence of HTLV-1 intrafamilial transmission in a non-endemic area in Argentina.
    Author: Gastaldello R, Otsuki K, Barbas MG, Vicente AC, Gallego S.
    Journal: J Med Virol; 2005 Jul; 76(3):386-90. PubMed ID: 15902707.
    Abstract:
    In the North of Argentina, an endemic area for HTLV-1, intrafamilial transmission of this virus has been observed. The HTLV-1 status in 13 family members of a seropositive blood donor from the central region of Argentina (non-endemic area) was investigated. According to serological and molecular assays, four members of this family (the blood donor, the husband, a son, and a daughter-in-law) proved to be HTLV-1 positive. LTR, tax, and env sequences from the provirus infecting the family members were identical. This strongly suggests the intrafamilial transmission of the virus. This study demonstrated intrafamilial transmission of HTLV-1 in a non-endemic area of Argentina.
