After a century of progress against infectious diseases in America, experts now warn of a “very worrisome trend."

Why it matters: Infectious diseases kill far fewer today than a century ago, the AP notes, but the numbers are moving in the wrong direction.

The Food and Drug Administration officially raised the age to buy tobacco in the U.S. from 18 to 21, fulfilling a key portion of the federal spending package that President Trump signed into law last week.

The big picture: The decision comes faster than some expected as the FDA had six months to amend their policies after Trump signed the bill and another 90 days to officially adopt the change. 19 states and the District of Columbia had already put in place laws to raise the minimum buying age for tobacco products — including cigarettes, cigars and e-cigarettes — to 21.
