The primary aim of epidemiology can be split into four areas: to characterise patterns of disease spread (descriptive epidemiology); to understand the factors underlying its spread (theoretical epidemiology); to predict its future course in the absence of intervention; and to evaluate the best options for treatment and control.

transmission of HIV-1 is the number of copies per mL of plasma HIV-1 RNA (viral load), with a 2·4 times increased risk of sexual transmission for every 1 log
Research has deepened our understanding of how the virus replicates, manipulates, and hides in an infected person. Although our understanding of pathogenesis and transmission dynamics has become more nuanced and prevention options have expanded, a cure or protective vaccine remains elusive.
