The Texas Department of State Health Services, in cooperation with the U.S. Centers for Disease Control and Prevention, confirmed a diagnosis of variant Creutzfeldt-Jakob Disease (CJD) in a patient who recently died in Texas.
Variant CJD was first described in 1996 in the United Kingdom and is a rare, degenerative, fatal brain disorder in humans. CDC says it is believed to be caused by consumption of products from cows with bovine spongiform encephalopathy.
This is the fourth case ever reported in the United States. According to the CDC, in each of the previous three cases, infection with the disease likely occured outside the United States. The agency said the fourth patient traveled extensively in Europe and the Middle East, which supports historical pattern of infection occuring outside U.S. borders.
