Don’t Tell Trump: Tuberculosis is another communicable disease that seems to be on the rise in the U.S., along with Chagas disease and enterovirus — with scientists and journalists seemingly befuddled as to what might be behind the increase. It’s a mystery! But the following buried sentences in the Tribune News service’s report may contain a clue:

Today four states – California, New York, Texas and Florida – have more than half the nation’s active TB cases, though they have only a third of the country’s population. The four states have the highest numbers of foreign-born residents. The number of cases in Texas rose 5 percent to 1,334 last year.
