The Hood River County Health Department (HRCHD) has confirmed one case and identified two probable cases of Creutzfeldt-Jakob disease (CJD) within the past eight months. Tragically, two of the individuals have died, and the third case is still undergoing testing for final confirmation.

This rare and fatal neurodegenerative illness affects approximately one to two people per million annually across the globe. In the United States, an estimated 350 cases are reported each year. For a county like Hood River, which is rural with a population of just 23,000, having three cases, in less than a year is statistically improbable.

Understanding Creutzfeldt-Jakob Disease

CJD is a prion disease, which means it is caused by misfolded proteins that damage brain tissue, creating sponge-like holes.

According to Dr. Brian Appleby, director of the National Prion Disease Pathology Surveillance Center, diagnosis typically requires examining brain tissue under a microscope for specific lesions and abnormal protein deposits.

Symptoms progress rapidly and may include confusion, hallucinations, loss of coordination, and behavioral changes.

The disease bears similarities to Bovine Spongiform Encephalopathy (BSE), or "mad cow disease," which affects cattle. BSE can, in rare instances, lead to a variant form of CJD in humans. Learn more about mad cow disease in humans here: Verywell Health.

Public Reassurance

HRCHD, in collaboration with the Oregon Health Authority (OHA) and the Centers for Disease Control and Prevention (CDC), is actively investigating these cases. Trish Elliott, director of HRCHD, stated:

"We're trying to look at any common risk factors that might link these cases… but it's pretty hard in some cases to come up with what the real cause is."

Healthcare providers have been alerted to watch for signs of rapidly progressing dementia, sudden behavioral shifts, and cognitive decline that may resemble Alzheimer's.

Despite the concerning cluster, HRCHD emphasizes that:

"The risk of getting CJD is extremely low. It does not spread through the air, touch, social contact, or water."

Ongoing Investigation

Information and updates are available on the Hood River County Health Department website.

“Per state law, the health department investigates and monitors diseases that could be a risk to the public. At this time, there is no identifiable link between these three cases.”

“People with questions about their healthcare are encouraged to contact their primary medical team.”
