Abstract
Objective: To analyze the vertical transmission of human T-cell lymphotropic virus (HTLV). Bibliographic review: HTLV is a human retrovirus that presents itself mainly in two forms: HTLV-1 and HTLV-2. These viruses affect T cells in the immune system and can lead to serious diseases, including T-cell leukemia, T-cell lymphoma, and HTLV-1-associated myelopathy, especially about 20 to 30 years after exposure. Transmission occurs through sexual contact, blood contact, and vertical transmission. Given the time required for severe manifestations, it is of extreme importance to discuss the vertical transmission of HTLV. Final considerations: It is considered that HTLV is a silent disease whose testing is not widely performed, and it is imperative to monitor its incidence for the implementation of preventive measures for vertical transmission of this virus. In addition, when considering measures to prevent mother-to-child transmission, the cost-benefit relationship should be considered in the recommendation to suspend breastfeeding, given its benefits to infants.
