New Brunswick Cluster of Neurological Syndrome of Unknown Cause
Cases under investigation 48
Deaths 6*
Illness onset date range in years 2013 – 2021**
Gender 50% female – 50% male
Age range in years 18 – 85
Timeline
Between January 2019 and July 2019, New Brunswick physicians identified a potential cluster of three Creutzfeldt-Jakob Disease (CJD) cases possibly related to cataract surgery.**An investigation conducted by the Creutzfeldt-Jakob Disease Surveillance System (CJDSS), in collaboration with Regional Health Authorities in NB, demonstrated that there was no relation between the CJD cases and the surgery.**Through routine case management, the CJDSS noted common symptoms and diagnostic profiles among recent NB referrals that tested negative for CJD and with negative cerebrospinal fluid (CSF) protein panels. It became apparent that these atypical referrals represented a second cluster, distinct from the first, that was worth further investigation.In December 2020, the CJDSS contacted Public Health New Brunswick to actively include the department in this investigation.The first draft for the case definition was gathered on January 29, 2021.A memo was drafted regarding this case definition and sent to NB physicians on March 5, 2021 to inform them and encourage any health-care provider with patients that may meet the case definition for this neurological syndrome of unknown cause, to please contact Public Health, the CJDSS or the Mind Clinic at 1-506-857-5569 for more information.
