title: A seminal finding for understanding HIV transmission.
abstract: Although the worldwide incidence of HIV infection is high, the retrovirus displays a surprisingly low infectivity in vitro. As a potential explanation for this discrepancy, Münch et al. (2007) now identify and characterize a factor found in human semen that under certain conditions can enhance HIV infectivity by more than 100,000-fold.
