Tuberculosis is very much with us.

"The World Health Organisation estimates that 14m people around the world had tuberculosis (TB) in 2009. Last year the disease killed 1.3m people who did not also have HIV. Another 400,000 people are counted as having died from AIDS but also having TB, to which HIV makes people more susceptible."

Two of the dozen of so colleagues with whom I worked in the White House many years ago were later diagnosed with TB and had to go through a long course of treatment. Of course, they were people who worked in international health, but it made an impression on me that the disease is serious and still with us!
