US autism rate unchanged in new CDC report

Researchers at the Johns Hopkins Bloomberg School of Public Health contributed to a new U.S. Centers for Disease Control and Prevention (CDC) report that finds the prevalence of autism spectrum disorder (ASD) largely unchanged from two years ago, at one in 68 children (or 1.46 percent). Boys were 4.5 times more likely to be identified with ASD than girls, an established trend. The rate is one in 42 among boys and one in 189 among girls.
