The first thing you notice about HIV statistics is how slippery they are. The Centers for Disease Control and Prevention’s AIDS surveillance says there were 46,268 diagnoses of HIV in 2010. The online Atlas provided by the CDC’s National Center for HIV/AIDS says there were 46,043.
It’s the same in Europe. Each country reports its own HIV statistics independently, then they’re gathered and re-reported by the European Centers for Disease Control. The Robert Koch Institute (Germany’s equivalent of the CDC) says 3,034 people were infected with HIV in Germany in 2008. The ECDC says it was 2,850.
Last year at the Smithsonian, I saw this documentary on exoplanets. Rocks in other solar systems don’t emit light, so the only way we can detect them is their tiny pull on the light waves coming from faraway stars. I was—am!—totally stunned at how we can see something so remote, so invisible, with our meager little tools on our provincial little planet.
I had a bit of the same are you fucking kidding me wonder talking to scientists about how they track the AIDS virus, and I could have easily gone another like 2,000 words on methodology alone. Public health is one of those achievements of modern civilization that gets (deserved) credit for stuff like eradicating smallpox and preventing cholera, but we should also give snaps to all the work that goes into just tracking and reporting diseases, just knowing what’s out there.
The data isn’t always available for every country, and it’s not perfectly comparable across them, but I’m glad someone out there is looking at all these little points of light, waiting for one of them to wobble.
