Investigations of environmental conditions during cluster indicate probable vectors of unknown exogenous agent(s) of multiple sclerosis.
During the tail-end of an active cluster several environmental investigations indicated that wildbirds were very probably the vectors of the unknown exogenous agent of MS. Canine distemper and genetic-autoimmune theories were very definitely eliminated because of the unusual pattern of the cluster. Studies of several avian pathogens unveiled Marek's (MDV) and/or IBD (Gumboro) as the most likely candidates for exogenous agent of MS.
