Two fatalities in Hood River County, Oregon, have renewed concern about Creutzfeldt-Jakob disease (CJD), a rare but devastating brain disorder. Local health officials confirmed these as CJD cases, underscoring how rapidly the disease can progress and its grim prognosis. The news unsettles residents in Oregon, and resonates with audiences in Thailand and around the world who track emerging infectious threats and past food-safety scares.
CJD is among the world’s rarest neurodegenerative illnesses, affecting an estimated one to two people per million each year. It is a prion disease, caused by abnormal proteins that trigger normal brain proteins to misfold, resulting in irreversible brain damage. Early symptoms typically include rapidly progressive dementia, movement problems, and psychiatric changes. Public health authorities note that most patients die within a year of onset. While many cases arise sporadically, others are inherited or, in very rare instances, transmitted through contaminated medical instruments or nerve tissue. Authorities in Hood River County have stressed that there is no evidence of a broader public health risk, nor any link between the two patients or to potentially infectious materials.
