There are similarities between multiple sclerosis and varicella.
They are common in the same parts of the world and both are scarce in other areas.
Immigration studies suggest the environmental cause of multiple sclerosis (MS) must be contracted prior to age 15 years and will usually remain dormant for years.
At age 10 years varicella has occurred in greater than 95% of children living in the high-risk areas for both of these diseases.
The varicella zoster virus (VZV) could be etiologically important in multiple sclerosis.
The known host containment of the virus for decades with recrudescence and the variable cell-mediated immunity of the host, which can wax and wane without clinical manifestations, all lend themselves to the natural history of multiple sclerosis.
A population-based study of the medical records of 5601 Hutterite Brethren was performed to determine the occurrence of multiple sclerosis, varicella, and herpes zoster.
Compared to their matched non-Hutterite neighbors who acted as controls, these events were significantly less common among the Hutterites.
Included in the study was an assessment of other common neurological diseases and « autoimmune » diseases among the Hutterites and the controls.
There is evidence of a relationship between MS and VZV that may not be coincidental.
