CDC: Zika Virus causes birth defects - UPI.com
UPI reports: "The Centers for Disease Control and Prevention said on Wednesday the Zika virus can cause birth defects like very small heads and other neurological damage in the fetuses of infected mothers. CDC officials said they had gathered enough data to make the announcement, putting to rest questions about whether microcephaly was caused by Zika. The findings are also being published in the New England Journal of Medicine."

Comment: Maybe I've been reading too many news reports on this subject, but I thought they'd already established that the virus caused birth defects?  I guess the individual studies, which they note, had previously prompted headlines saying the link had been established but this represents an authoritative conclusion announced by the medical community.
