Staying Power

Treatment programs against tuberculosis have largely kept the potentially fatal airborne disease under control in the U.S.—the incidence has been dropping steadily since 1992. But the disease's persistence worldwide and multidrug-resistant strains, created perhaps by incomplete courses of antibiotics, still pose challenges. A study examining data between 1994 and 2003 (the latest available) in California, the state with the greatest number of cases, highlights the issues.

Number of U.S. tuberculosis cases, 2003: 14,874

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
