New developments in the biology and treatment of HIV

Abstract
Until about 2 years ago, medical science could offer little to alter the course of HIV-1 infection. After initial transmission of HIV, viral particles accumulate in blood to high levels within a few weeks, but levels then fall concomitant with the onset of the host immune response. Thereafter, the disease usually remains quiescent for a prolonged period, often for years or even decades, a phase termed clinical latency.
