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.


  • Measles hit their highest U.S. rate in 27 years, concentrated among Orthodox Jews.
  • Hepatitis A is up more than 10x from 2017, sparked by an outbreak among the homeless and drug users.
  • And eastern equine encephalitis killed 15 of the 38 people diagnosed this year. The 38 cases is double the previous rate.

The big picture: America remains very fortunate compared to our fellow global citizens.

  • Measles killed 142,300 people worldwide in 2018, compared to zero in the U.S. in 2019.

Between the lines: America's measles elimination status isn't as important as "the fact that we remain highly vulnerable," Baylor pediatrics professor Peter Hotez told Axios' Eileen Drage O'Reilly earlier this year.

  • There are "at least 100 geographic pockets in the U.S. where a high percentage of kids are not being vaccinated, together with measles cases now regularly imported from Europe where measles is even more widespread," Hotez said.

The bottom line: Backsliding is bad, particularly when it's largely the result of human choices, rather than mother nature's ingenuity.
