Risk factors and epidemiology of human T-lymphotropic virus types 1 and 2 in US blood donors [PDF]

Retrovirology, 2015
Blood donations in the US are routinely screened for markers of human T-lymphotropic virus (HTLV). Seroprevalence and risk factors associated with HTLV-1 and -2 infection from the US Retrovirus Epidemiology Donor Study (REDS-II) Transfusion-Transmitted Viral Infection (TTVI) Rate and Risk Factor Study are reported.

Human T-lymphotropic virus 1/2 infection among immigrants and refugees in Central Brazil, an emerging vulnerable population

Frontiers in Public Health, 2023
IntroductionMigratory flows play a significant role in the spread of human T-lymphotropic virus 1/2 (HTLV-1/2). In the last decade, a substantial migration of individuals occurred from Haiti and Venezuela to Brazil. However, data on the prevalence of HTLV-1/2 infection among these international migrants in Brazil are scarce.

The prevalence of human T‐lymphotropic virus type 1 & 2 (HTLV‐1/2) in South African blood donors

Vox Sanguinis, 2019
Background and objectivesDonated blood is not currently screened for human T‐cell lymphotropic virus (HTLV) in South Africa. Several small studies have detected HTLV‐1 in South Africa, but prevalence by geographic region or population group is unavailable.Materials and MethodsWe performed a large seroprevalence study of South African blood donors ...

Induction of CC-Chemokines with Antiviral Function in Macrophages by the Human T Lymphotropic Virus Type 2 Transactivating Protein, Tax2 [PDF]

Viral Immunology, 2013
Recent data provide evidence that co-infection with human immunodeficiency virus type 1 (HIV-1) and human T lymphotropic virus type 2 (HTLV-2) delays progression to AIDS compared to isolated HIV-1 infection. These results were linked to expression of the HTLV-2 transcriptional activating gene known as Tax2.

Infectious Agents As Markers of Human Migration toward the Amazon Region of Brazil

Frontiers in Microbiology, 2017
Infectious agents are common companions of humans and since ancient times they follow human migration on their search for a better place to live. The study of paleomicrobiology was significantly improved in its accuracy of measurement with the constant ...

Infection with human T-lymphotropic virus types-1 and -2 (HTLV-1 and -2): Implications for blood transfusion safety [PDF]

Transfusion Clinique et Biologique, 2016
Many countries currently perform antibody screening for HTLV-1 infection in blood donors, and this intervention is likely cost-effective in preventing HTLV-1 related diseases in high prevalence countries. However, a number of high-income countries with low prevalence of HTLV-1 infection also perform universal HTLV-1 screening and debate has arisen ...

Clinical Outcomes and Disease Progression among Patients Coinfected with HIV and Human T Lymphotropic Virus Types 1 and 2 [PDF]

Clinical Infectious Diseases, 2004
The goal of this study was to investigate clinical outcomes and survival probabilities among persons coinfected with human immunodeficiency virus (HIV) and human T lymphotropic viruses types 1 and 2 (HTLV-I/II). A nonconcurrent cohort study of 1033 HIV-infected individuals was also conducted.
