well, the numbers look a little high for here.
there's under 300,000 people in my country...
at a rate of 5-20 per 100k, that means... 15 - 60.
I personally know of four here, and they're all expats.
meaning, they already had MS before they arrived.
I checked with a half-dozen doctors, and they know of NO Belizeans with MS, except one, who was raised in the US from infancy, and returned as an adult.
since MS is virtually unknown here, it's a ^#@* to get standard meds like Baclofen...
