HIV Transmission and prevention

01May17
HIV transmission has reached a new record high of 244 cases in New Zealand in 2016. This follows a consistent upward trend that has been happening since 2011. Most of the cases 159 or 65% were amongst men who have sex with men with the majority 98 or 61.6% of these infections taking place within New Zealand. Amongst the Heterosexual population there were 42 new diagnoses with 11 of these infections being local.

For people not diagnosed and infected locally they may have been living with HIV for a period of time and have been engaged in care elsewhere and have just returned to New Zealand (from Australia or the UK for example) and their diagnosis is defined as “new” to New Zealand. We will always have these types of new diagnosis as people are allowed to migrate to NZ while living with HIV – which is a good thing. Read More...

Undetectable equals Uninfectious (U=U)

25Jan17
Body Positive is celebrating the most significant development in the HIV world since the advent of effective combination therapy 20 years ago – people living with HIV who maintain undetectable viral loads through adherence to treatment can confidently declare to their sexual partners “I’m not infectious!”  Read More...

Still no transmissions seen from people with an undetectable viral load in PARTNER study

PARTNER Study - still zero transmissions
Odds of seeing a transmission now even lower, but more data still needed on gay men, say researchers

The PARTNER study, which two years ago created headlines by establishing that the chance of an HIV-positive person with an undetectable viral load transmitting their virus was very low and quite possibly zero, released new data at the 21st International AIDS Conference (AIDS 2016) that further refined this estimate.

Latest NZ figures show a rise in annual HIV diagnoses

04June15
The latest figures for HIV in NZ shows the highest number of diagnoses for Gay and Bi-men since the HIV epidemic began. There has been a consistent increase over the past 3 years. In addition there is a marked increase in the number of recent local infections over previous years which may indicate an increase in recent transmission. While this shows that people are testing earlier and are taking control of their health it raises concerns over the increasing number of people now living with HIV. With more people being diagnosed with HIV and people now living longer through improved clinical care we now have 2900 people living with HIV in NZ at the end of 2014. Read More...

Depression strongly associated with risky sex in UK gay men

03Jun15_1
HIV-negative gay men who have several symptoms of depression are more likely to report sex without a condom, according to a study presented to the British Association for Sexual Health and HIV (BASHH) conference in Glasgow.

Several past studies have shown that poor mental health is frequently experienced by gay men. Some American studies have found an association between depression and risky sex, or depression and seroconversion to HIV, but there has been little data on the issue in HIV-negative gay men in the UK.

No HIV transmissions from HIV-positive partner seen in Australian gay couples study

01Mar15
An Australian-based study of gay male couples of opposite HIV status (serodifferent couples) has so far seen no transmissions from the HIV-positive partner within the couple in a two-year interim analysis.

The Opposites Attract study started recruiting in May 2012. It recruits gay male serodifferent couples regardless of whether the HIV-positive partner is on antiretroviral therapy (ART) or has an undetectable viral load, and also regardless of whether or not they use condoms. Read More...

HIV most often passed on by younger gay men who have undiagnosed HIV, are not on treatment, and have an ongoing partnership

17Dec14
A modelling study based on the UK’s HIV epidemic among gay men estimates that two-thirds of infections originate in men with undiagnosed HIV, 85% in men who are not taking treatment and 90% within the context of an ongoing sexual partnership. Moreover, HIV transmissions most frequently involve men under the age of 35 who report relatively high levels of sexual activity, according to the study published online ahead of print in AIDS.

But the findings suggest that men with primary infection contribute less to onward transmission than is sometimes thought. Read More...

Second analysis concludes that we can’t eliminate the long-term possibility of HIV transmission from someone on treatment

14Jul14
A study that estimates the risk that someone living with HIV and taking antiretroviral therapy could transmit the virus reports that, on the basis of the few transmissions from heterosexual partners on treatment that have been reported, it is not possible to dismiss the risk of infection as zero.

The analysis by French researchers in Clinical Infectious Diseases estimates that the highest-likely risk of HIV being transmitted is between 8.7 and 13 transmissions per 100,000 sex acts; in other words, from one in about 11,500 to one in about 7700 acts. However, the researchers stressed to aidsmap.com that this is the highest-likely risk: the actual risk may be lower than this and could indeed be zero. Read More...
