‘Disturbing’: US infant mortality rises at highest rate in 20 years

CDC data shows rate rose 3% last year but experts say they are not sure why statistic that has been falling should have risen sharply

The US infant mortality rate rose 3% last year - the largest increase in two decades, according to the Centers for Disease Control and Prevention.

White and Native American infants, infant boys and babies born at 37 weeks or earlier had significant death rate increases. The CDC's report, published Wednesday, also noted larger increases for two of the leading causes of infant deaths - maternal complications and bacterial meningitis.
