Canada has just lost measles elimination status. The U.S. will undoubtedly follow shortly.
Elimination means that there is no continuous spreading of measles within the country for a year or longer.
Canada and the U.S. have blown it, and it’s largely the fault of the anti-vaccination movement.

This is 67 cases--a tiny fraction of TB's global burden, which exceeds 10,000,000 active cases per year.
But the longer we allow a curable illness to infect and kill millions, the more TB we'll see in the U.S. Tuberculosis is an airborne disease, and TB anywhere is a threat to humans everywhere.
