In a follow-up to a June 2, 2014 report of the fourth vCJD case in the United States in Texas, health officials from both the Centers for Disease Control and Prevention (CDC) and the Texas Department of State Health Services (DSHS) completed their investigation into where the individual contracted the 100% fatal prion disease.

On Oct. 7, 2014, the following was reported:

The investigation confirmed that the case was in a US citizen born outside the Americas and indicated that the patient’s exposure to the Bovine Spongiform Encephalopathy (BSE)/Variant Creutzfeldt-Jakob Disease (vCJD) agent most likely occurred before he moved to the United States; the patient had resided in Kuwait, Russia and Lebanon. The completed investigation did not support the patient’s having had extended travel to European countries, including the United Kingdom, or travel to Saudi Arabia. The specific overseas country where this patient’s infection occurred is less clear largely because the investigation did not definitely link him to a country where other known vCJD cases likely had been infected.
