No association between prenatal exposure to influenza and autism

[Guest guest]

what register with the NAS? I wasn't aware they had one (and I'm a

member and help run a local branch!). I'm, sure my son isn't listed on

any register. Seems a potentially ropey study. Many families with

autism don't join the NAS for various reasons.

Some conversation on another list prompted some more searching on the

connection between flu and autism and this was found. Just wanted to

pass it along to those that might be interested.

Thanks. Problem with this article--as written below-- is that a

person doesn't get " exposed " to an epidemic--only exposed to a virus

(influenza) during the epidemic. In

addition, the relationship in question is for pregnant women/their

child who are infected with the virus and actually have the disease.

I wouldn't say the study shows much of

anything about a relationship if they are only talking about

potential exposure v. actually having the disease. Unfortunately it's

not clear from the description what they

actually studied.
