"With high adherence, PrEP saves money in high-prevalence populations even at current costs." From AIDSmap, Gus Cairns reports.

New US PrEP cost-effectiveness model finds drug prices will need to drop substantially if HIV risk rises, or if adherence is only moderate

A new US model of the cost-effectiveness of pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM), prepared by researchers at Emory University in Atlanta, finds that taking even one year of PrEP is more cost-effective than measures like kidney dialysis, if it is used by people belonging to populations where HIV prevalence is at least 10%. However, for PrEP to actually save money, relative to the lifetime cost of treating the HIV infections that would otherwise happen, either

Who are trans women acquiring HIV from? And are trans women's partners a hidden population?

Is there a hidden population of heterosexual men who have sex with trans women and who are themselves at high risk of acquiring and transmitting HIV? From AIDSmap, Gus Cairns reports on a study that begs this question and others.

Who are trans women acquiring HIV from? And are trans women's partners a hidden population?

There is a lot we don’t know about trans women’s HIV risk, why they are so vulnerable to HIV and who trans women are acquiring HIV from. A study presented at last month’s 9th International AIDS Society Conference on HIV Science (IAS 2017) attempted to answer these questions, but in the process uncovered another mystery. This is whether there is a hidden population of heterosexual men who have sex with trans women and who are themselves at high risk of acquiring and transmitting HIV. On

From AIDSmap, Gus Cairns reports on evidence from the Opposites Attract study that was presented this week at #IAS2017 in Paris.

The Opposites Attract study looked at whether HIV is transmitted between gay male couples of different HIV status when the HIV positive partner is on treatment

Swiss Grindr survey finds 50% want to use PrEP in the next six months

From AIDSmap, Gus Cairns reports on a survey showing twice as much interest in PrEP as in surveys done last year

Swiss Grindr survey finds 50% want to use PrEP in the next six months

A survey of Swiss gay men and men who have sex with men recruited through the Grindr networking app has found that while only 4.3% had taken HIV pre-exposure prophylaxis (PrEP), 50% would consider taking it within the next six months and 79% would either take it some time in the future or want to learn more about it. The survey was a brief one both in terms of its appearance online (from 5 to 24 January this year) and in terms of its length (only ten questions taking, it was estimated,

HIV’s milder cousin may be less mild than previously thought

Gus Cairns: Seventy per cent of people with HIV-2 progress to AIDS within 20 years

HIV’s milder cousin may be less mild than previously thought

HIV-2’s virulence may have been underestimated and although progression to AIDS  and death in HIV-2 infection was slower than with HIV-1, it was the rule rather than the exception, new research from West Africa presented at last month's Conference on Retroviruses and Opportunistic Infections (CROI 2017) indicates. HIV-2 crossed over into human beings from the sooty mangabey monkey, rather than from chimpanzees and gorillas like HIV-1. Its entry into humans probably precedes that of HIV

STI rates in PrEP users very high, but evidence that PrEP increases them is inconclusive

AIDSmap.com's Gus Cairns: Modelling study predicts STI rates will fall with regular testing

STI rates in PrEP users very high, but evidence that PrEP increases them is inconclusive

A study of pre-exposure prophylaxis (PrEP) users presented at the Conference on Retroviruses and Opportunistic Infections (CROI 2017) last week in Seattle, showed that PrEP users had very high rates of sexually transmitted infection (STI) diagnosis – in the order of 20 times higher than among HIV-negative gay men in the general population. There was also an increase in STI diagnoses from a time point a year before they sought PrEP to the date they started it. And the percentage of men r

One in five ‘heterosexual’ men in the UK caught their HIV from another man.

From AIDSmap.com, Gus Cairns reports on new data presented by Manon Ragonnet-Cronin and colleagues from Edinburgh University at the 2017 Conference on Retroviruses and Opportunistic Infections (CROI) last week.

One in five ‘heterosexual’ men in the UK caught their HIV from another man.

A genetic analysis of a large database of people with HIV in the UK in care shows that 18% of men with HIV who claim to be exclusively heterosexual in fact belong to clusters of linked infections that consist only of men. This provides a minimum figure for the proportion of men with HIV in the UK who are what the researchers call “undisclosed men who have sex with men (MSM)”. It is a minimum figure because other men who caught HIV through sex with another man may be in mixed-gender cluste

Nearly two-thirds of European HIV cases are now in Russia

AIDSmap.com: Static picture in other countries conceals local change, especially in gay men. Gus Cairns reports.

Nearly two-thirds of European HIV cases are now in Russia

The annual number of new cases of HIV increased by at least 8% in 2015 in the whole of the World Health Organization (WHO) European region, and by 60% in the last decade, according to last month’s annual surveillance report by the European Centre for Disease Control (ECDC) and WHO Europe. A continued increase in new diagnoses in Russia was responsible for most of the increase. The previous year, as aidsmap.com reported, 60% of European-region new cases were in Russia. In 2015 this increase

The UK’s largest sexual health clinic saw a 40 percent drop in new HIV infections this year

The UK’s largest sexual health clinic saw a 40 percent drop in new HIV infections this year

The clinic at 56 Dean Street in Soho, central London, the largest sexual health clinic in the UK, saw an unprecedented 40% drop in new HIV diagnoses this year. A press release from the Chelsea and Westminster Hospital, which runs Dean Street, said that in the period between January and November 2016, the clinic diagnosed 373 new HIV infections. In the same period in 2015, they diagnosed 626 – a fall of 40.4%. The Dean Street clinic accounts for one in nine HIV diagnoses in the UK and one

Gay men with overlapping partnerships are more likely to be recently and locally infected

Study provides evidence that concurrent relationships sustain HIV transmission. From AIDSmap, Gus Cairns reports.

Gay men with overlapping partnerships are more likely to be recently and locally infected

A study analysing transmission patterns between gay men in a cohort of patients on San Diego, California has found the strongest scientific evidence so far that concurrency – having ongoing sexual relationships with more than one partner at the same time – is an independent predictor of HIV transmission. It found that men who said they had had condomless sex in the last three months with concurrent partners, rather than just serial partners, were 69% more likely to be in a local transmi
