Distance From The Equator
This graph demonstrates the risk of getting Multiple Sclerosis depending on how far you live from the equator. The graph shows us that the countries that are farther away from the equator have a higher chance of contracting this autoimmune disorder. For example, Italy and Canada have a very high prevalence of Multiple Sclerosis due to the distance from the equator, whereas Kenya and Cameroon have a very low prevalence of MS due to the fact that they are very close to the equator.
