Even the tiniest misprint in a person’s genetic code can cause big health problems, but they can be hard to find. Now members of a team at University of Washington say they’ve designed a better way to track down those mutations.

If you think of DNA as a twisted ladder, each rung is made of two little structures called bases, stuck together. If even one of the billions of these rungs gets copied wrong it can have serious consequences, such as which kind of tuberculosis you get.

The doctors are calling them "totally drug-resistant TB," and the infections are essentially incurable with all available medicines.

One of every three of us on planet has TB; Seattle rates remain twice national average

My friends always tend to disbelieve me (in general, but also specifically) when I tell them that one out of every three people on the planet has been infected with tuberculosis.

So where are all these consumptive folks, they might say? — This is assuming they know that TB used to be called consumption because of the way it “consumed” and withered the body as the infection progressed.

They’re everywhere, I’d reply, including right here in wealthy and smug Seattle.

Seattle, in fact, has one of the worst problems with TB in the nation. But it’s always here, managed by the public health folks, so it’s hardly news.

The news is that it’s World TB Day.
