PrEP makes no sense for discordant couples – corrected (15/07/11)

First PReP worked for gay men, and we were happy. Then it didn’t work for straight women, and we were sad. Now, two big studies in heterosexuals have shown it can work for straight couples, and we are deeply confused. Or at least I am. Taking anti-HIV pills every day cuts the risk of infection […]

HIV: a right of passage for gay men? (24/09/10)

It’s taken two whole years, but US CDC has finally published data from the 2008 round of HIV and behavioural surveillance in gay men in 21 cities. Nearly one in five gay men is infected; in some cities (notably Baltimore) it is twice as high, at 38%. Reacting to the report, CDC’s HIV prevention director […]

Is CDC’s HIV prevention trial in Thailand ethical? (24/01/10)

How ethical are HIV prevention trials? Every time we announce results of a trial that compares new HIV infections in a group with or without some new intervention (a microbicide for example, or a vaccine), some journalist or other jumps on the fact that researchers are just watching people get infected. Researchers then explain that […]

HIV surveillance, US style: don’t try this at home (14/04/09)

For a world-renowned centre of epidemiological excellence, the US CDC can do some pretty shonky work. This week, the second week of April, 2009, they have finally published some results from surveillance among drug injectors carried out more than three years ago. And the analysis is so simplistic that it tells us virtually nothing about […]

Tell us something new dept: In the US, HIV is gay and black (12/09/08)

A little while ago, CDC estimated how many people were newly infected with HIV in the US in 2006. They told us it was a disease of gay men and black people. Now they’ve done more detailed analysis: It’s not just a disease of gay men and black people. It’s increasingly a disease of gay […]

Largely in New York: new HIV is young, black and gay (01/09/08)

New York likes to think of itself as ahead of the rest of the US on many fronts. It certainly is on the HIV front. In most of the world, we’ve got precious little idea how many people get infected with HIV each year. Generally, we report HIV prevalence — the number of people who […]

AIDS in America: More is less? (10/08/08)

What’s going on with AIDS in the US? I’ve finally had time to comb through CDC’s estimates of new HIV infections in the US, and I’m frankly little the wiser. Last week the Centers for Disease Control and Prevention (CDC) suddenly declared that around 55,000 Americans are getting infected with HIV each year (the estimate […]

The White House vs Science: what’s a girl to do? (31/01/08)

Salon’s Sheila Kaplan, Newshoggers and Michael Clark bring to our attention the latest salvo in the Bush administration’s war on science — this time, it was suppressing information about possible toxicity of trailers used to house victims of Hurricane Katrina because of formaldehyde, though it might just as well be the safety of condoms (which […]
