How HIV Possibly Jumped From Monkey To Man

Asian Scientist, April 12, 2018

Scientists in Japan have discovered a protein that may have enabled the simian immunodeficiency virus (SIV) to be transmitted to humans. Their findings are published in Cell Host & Microbe. The human immunodeficiency virus (HIV) is believed to have evolved from a SIV that originated in chimpanzees.

HIV vaccine therapy lets five people control virus without drugs

New Scientist, 22 February 2017

FIVE people with HIV are currently free of detectable virus – and daily drugs – thanks to a new vaccine-based therapy.

Although it is early days, one participant has been drug-free for seven months.

ZERO: no linked HIV transmissions in PARTNER study after couples had sex 58,000 times without condoms

HIV Treatment Bulletin,  12 July 2016

The PARTNER study showing the impact of HIV treatment (ART) on reducing transmission will benefit millions of people globally.

The results set a new challenge about whether transmission is anything other than a theoretical risk when someone is taking effective ART. This reverses the common assumption that, by definition, some level of risk always exists when one partner is HIV positive.

The PARTNER study provides good evidence that undetectable viral load might be a threshold below which sexual HIV transmission does not occur. The importance of the PARTNER study is that it included both gay and straight couples, that it measured risk in people who were not using condoms and that it estimated absolute risks.

HPV May Cause A Genital Infection That Leads To Cancer, And Not Just Cervical

Medical Daily, Jul 2, 2016 04:40 PM

The authors of a new study published in Cancer, Epidemiology Biomarkers & Prevention looked at 34 years of data on nearly 3 million women. And it turns out, women with HPV are at risk for more than cervical cancer.

The study’s findings suggest that women with HPV are at long-lasting risk for anogenital cancers too. Lead study author Susanne Krüger Kjær believes that preventing HPV infection from occurring in the first place may be the best way to drive down subsequent cancer rates.

Australia’s annual report card on HIV, hepatitis and STIs

Guardian, 14 September 2015

Australia’s HIV contraction stabilises but 1,000 a year still return positive tests:

The number of Australians contracting HIV has stabilised but about a thousand people a year are still returning positive tests, and about a quarter of those people have had the virus for at least four years without realising it.

The latest report card on the nation’s sexual health, by the University of New South Wales’s Kirby Institute, is a mixed bag. It is the nineteenth annual review of available surveillance data pertaining to the occurrence of HIV, viral hepatitis and sexually transmissible infections in Australia.

Why do certain hormonal contraceptives increase the risk of HIV?

American Society for Microbiology, 1st September 2015

In recent years, evidence has been building that injectable contraceptive depot medroxyprogesterone acetate (Depo-Provera or DMPA) is associated with an increased risk of HIV infection. Now a study published in the September 1st issue of mBio, an online open-access journal of the American Society for Microbiology, provides a biological explanation for the phenomenon.
