The rate of US cases rose to about 1 in 88 children. The previous estimate was 1 in 110.
The new figure is from the latest in a series of studies that have been steadily increasing the government's autism estimate. This number means autism is nearly twice as common as officials said it was only five years ago and likely affects roughly 1 million US children and teens.
Health officials attribute the increase largely to better recognition of cases through wide screening and better diagnosis. But the search for the cause of autism is really only beginning, and officials acknowledge that other factors may be helping to drive up the numbers.
