British man who once lived in Houston has mad cow disease

A man from Great Britain who lived in Houston for four years has the human form of mad cow disease, the U.S. Centers for Disease Control and Prevention confirmed Monday.
The 30-year-old's case was considered the second U.S. diagnosis of variant Creutzfeldt-Jakob disease because his symptoms began while he lived in Houston.
He returned to Great Britain this year, and he is receiving medical treatment for the fatal illness.
