death rate

President Trump says the nation's death rate is likely to peak in two weeks, and he says he's extending his 15-day "stop the spread" guidelines until April 30.

Overall, U.S. life expectancy dipped in 2015 — the first drop since 1993. That's because the death rate went up between 2014 and 2015, driven by an increase in mortality among people younger than 65.

The death toll from pneumonia and other infectious diseases in the U.S. is much lower than it was 100 years ago, but new pathogens like the West Nile, dengue and Zika viruses pose challenges.
