Multiple sclerosis is an autoimmune disease, and it’s not a communicable disease.

Multiple sclerosis has no known cause for the moment, but it is believed that is a combination of environmental and genetic factors. However, it is a well known fact that people that live closer to the equator have less chances of developing this disease. This is partially due to the fact that people who live closer to the equator, because of the sun, produce more vitamin D, and vitamin D deficiency is closely linked to MS. Nevertheless, it’s no guarantee that people who live closer to the equator won’t have MS, as it’s no guarantee that people that live in a temperate climate will develop it.

It’s needless to say, that for the moment, there is no single case of communicating this disease. Children that are born from parents diagnosed with MS bear the risk of developing this disease into adulthood though (there are between 20%-30% chances).

Summing it up, the chances of “catching” MS from a person are 0% - unless that person is a close blood relative, but even in this case you won’t catch it from them, you were born with a genetic predisposition to multiple sclerosis.
