Taking antiretrovirals is key to reducing HIV infection rates, but the challenge lies in making sure people who know they are infected actually take the drugs.
Current epidemiological and financial trends suggest there's a major risk of a substantial shortfall in the funds required to sustain life-saving antiretroviral programmes.
Curing HIV – or at least achieving long-term remission – is possible, under the right circumstances.
Three new studies conducted in South Africa provide insights into the engine that drives HIV transmission in the country.
Activists, health-care workers and scientists in South Africa were faced with a horrific epidemic but went on a ruthless crusade to turn it around.
New guidelines from the World Health Organization mean more people are eligible for antiretrorviral therapy. It's critical to find ways for people to start treatment without multiple clinic visits.
In South Africa, female sex workers go for HIV tests, receive counselling and use condoms – but don't access antiretroviral treatments. More options are now available and can change this.
Interacting with communities can provide health planners with critical information that can help them solve health challenges in specific areas.
The call to action to address childhood vulnerability in Africa must go far beyond the 17.8 million children infected and affected by HIV.
In sub-Saharan Africa more women may be infected with HIV than men - but men are more likely to die because of poor testing and treatment regimes.
Despite the breakthroughs in HIV and AIDS research, without an effective vaccine, the world will not get to zero new infections and deaths.
Globally, the health community is moving to a point where there could be zero new HIV infections or deaths. But it has been a long road.
The closure of several mines in South Africa and production cuts could have a detrimental impact on the health of miners who rely on in-house HIV and TB treatment programmes.
Thanks to treatment advances, people with HIV can and do live long and full lives. And that has led to a challenge that doctors and patients may not have imagined 35 years ago: the aging HIV patient.
Just how much disclosure is it reasonable to expect from a sex partner, particularly if that relationship isn't a serious and committed one?
Researchers have found a promising way of kicking the AIDS virus out of its hiding place in infected cells, potentially removing the main obstacle to curing HIV.
Viruses cause all kinds of infections from relatively mild cases of the flu to deadly outbreaks of Ebola. Clearly, not all viruses are equal and one of these differences is when you can infect others.
Starting HIV treatment early, before immune damage occurs, brings real clinical benefits, a new study has shown.
A new pill available could enable people living with HIV to conceive children through sex without risking the health of their HIV-negative partner.
Immunotherapy has joined anti-retroviral drug therapy as a means to combat HIV.
