(CNN) -- Doctors and hospital officials from Novant Health Forsyth Medical Center in Winston-Salem, North Carolina, are notifying 18 neurosurgery patients that they might have been exposed to Creutzfeldt-Jakob disease, a serious and incurable neurological disorder.
"Today we are reaching out to 18 neurosurgery patients who were exposed to Creutzfeldt-Jakob disease over the last three weeks at Forsyth Medical Center," said Jeff Lindsay, president of the center, according to CNN affiliate WGHP.
According to the National Institute of Neurological Disorders and Stroke, CJD affects about one person in every one million people per year worldwide.
The hospital confirmed that on January 18, an operation was performed on a patient with CJD symptoms who later tested positive for the illness.
Even though the surgical instruments were sterilized by standard hospital procedures, they should have gone through enhanced sterilization procedures used when there are confirmed or suspected cases of CJD.
The Centers for Disease Control and Prevention, as well as the World Health Organization, recommends that surgical equipment used on CJD patients be destroyed or decontaminated through an intense disinfecting process.
Although CJD can be transferred through surgical equipment, hospital officials say the likelihood of these patients contracting the disease is very low.
The CDC corroborates that assessment.
It says that no cases of the disease have been linked to the use of contaminated medical equipment since 1976.
But Lindsay made no excuses.
"On behalf of the entire team at Novant Health, I apologize to the patients and their families, for having caused this anxiety."
In September, 13 patients received similar warnings from two hospitals in New Hampshire and Massachusetts, when a patient who had undergone neurosurgery was later suspected to have CJD.
The hospitals shared the specialized surgical equipment that was used to operate on the patient and continued to use it until the suspicion of exposure to the disease surfaced.
