To estimate how frequent autism is, the CDC checked well being and faculty data for 8-year-olds, as a result of most circumstances are identified by that age. Different researchers have their very own estimates, however specialists say the CDC’s estimate is essentially the most rigorous and the gold normal.
This is what you want to know concerning the new numbers, in addition to Well being Secretary Robert F. Kennedy Jr.’s plan to do a “massive testing and research effort” round autism.

Various research, together with some with CDC authors, haven’t discovered such hyperlinks.
Final week, Kennedy stated HHS was launching “a massive testing and research effort that’s going to involve hundreds of scientists from around the world” and establish what causes autism in lower than six months. He additionally promised “we’ll be able to eliminate those exposures.”
Kennedy and President Donald Trump each referred to the 1-in-31 estimate that CDC launched Tuesday throughout final week’s White Home assembly, and Kennedy additionally repeated the statistic at a gathering with FDA officers on Friday,
Kennedy’s assertion adopted reviews that he had employed David Geier, a person who has repeatedly claimed a hyperlink between vaccines and autism, to steer the autism analysis effort. The hiring of Geier, whom Maryland discovered was practising medication on a toddler with out a physician’s license, was first reported by The Washington Put up.
