Africa is the largest endemic area for HTLV-1, with many molecular genotypes. We previously demonstrated that some strains from North Africa (a-NA clade) originated from a recombinant event between Senegalese and West ...

Human immunodeficiency virus type 2 (HIV-2) was isolated in AIDS patients in 1986. Around 1-2 million people are infected worldwide. The virus is less transmissible than HIV-1, being sexual contacts the most frequent route ...

Since the first report of a cluster of pneumonia cases in Wuhan (China) at the end of 2019 due to a new airborne highly transmissible coronavirus known as SARS-CoV-2, large-scale spreading has rapidly become a global ...

The meta-analysis published by Gill Schierhout and colleagues1 reported an increased relative risk of premature death in individuals infected with HTLV-1 compared with individuals not infected with HTLV-1 (RR 1·57, 95% CI ...

Medical and social attention to HIV infection has declined globally and is increasingly focused on developing regions, where the epidemic is still largely uncontrolled. In North America and western Europe, AIDS is rarely ...

Background: HIV-1 and HIV-2 differ in their antiretroviral (ARV) susceptibilities and drug resistance mutations (DRMs). Methods: We analyzed published HIV-2 pol sequences to identify HIV-2 treatment-selected mutations ...

OBJECTIVE: To examine the clinical burden and disease spectrum, as well as time trends for human T-cell leukemia virus type 1 (HTLV-1) and HTLV type 2 (HTLV-2) hospital admissions. DESIGN: Retrospective, observational study ...

A relationship between the infecting dose and the risk of disease severity has not been demonstrated for SARS-CoV-2 infection. Here, we report three clusters of individuals that were potentially exposed to distinct inoculum ...

Nanoformulations of cabotegravir prodrugs have been developed to prolong the pharmacokinetics of the antiretroviral agent. They can be present in the plasma of mice and non-human primates for a year following a single injection.

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has hit health-care systems and societies in an unprecedented manner. In 1981, the first cases of AIDS were reported and wide diagnostic ...
