HIV: the changing paradigm

The past four decades have seen enormous progress in the diagnosis and management of human immunodeficiency virus (HIV) infection. There have been significant advances spanning the approval of the first antiretroviral agents, the advent of combination antiretroviral therapy to single tablet regimens with minimal toxicity. Although these remarkable developments have on the surface led to the 'end of AIDS', there are still key populations being left behind. This clinical update will describe the diagnosis and management of HIV, and the changing paradigms that have seen HIV transform from a life-limiting condition to a manageable chronic disease over a few decades.

HIV-1 subtype diversity, transmitted drug resistance and phylogenetics in Australia

Australia has maintained a low prevalence of HIV, with a mainly concentrated epidemic and successful public health response. With the widespread availability of HIV genotyping for resistance testing, and development of phylogenetic methodologies, the field of molecular epidemiology has evolved a deeper understanding of diversity and transmission dynamics of HIV. Studies combining HIV genotype with epidemiological data have allowed insights to be gained into the changing subtype diversity, rates of transmitted drug resistance and transmission networks of HIV in Australia. This review provides an overview of HIV molecular epidemiology studies in Australia.
