Human T-lymphotropic virus type II (HTLV-II) is a human retrovirus which is endemic in
Amerindian and pygmy tribes. Molecular subtypes show geographic segregation consistent …

Using both env and long terminal repeat (LTR) sequences, with maximal representation of
genetic diversity within primate strains, we revise and expand the unique evolutionary …

The human T-lymphotropic viruses (HTLVs) types 1 and 2 originated independently and are
related to distinct lineages of simian T-lymphotropic viruses (STLV-1 and STLV-2 …

Background Hunting and butchering of wild non-human primates infected with simian
immunodeficiency virus (SIV) is thought to have sparked the HIV pandemic. Although SIV …

The recognition that AIDS originated as a zoonosis heightens public health concerns
associated with human infection by simian retroviruses endemic in nonhuman primates …

Studying the transmission of simian retroviruses to humans can help define the importance
of these infections to public health. We identified a substantial prevalence (4/231, 1.8%) of …

Risk factors for male-to-female sexual transmission of human T-lymphotropic virus types I
and II (HTLV-I/II) were investigated among HTLV-seropositive volunteer blood donors and …

Human T-lymphotropic virus type 1 (HTLV-1) is found in indigenous peoples of the Pacific
Islands and the Americas, whereas type 2 (HTLV-2) is widely distributed among the …

The first description of the human T-lymphotropic virus type 1 (HTLV-1) was made in 1980,
followed closely by the discovery of HTLV-2, in 1982. Since then, the main characteristics of …

Human T lymphotropic virus, type II (HTLV-II), infection has been shown to be endemic in a
number of American Indian populations, and high rates of infection have also been …
