Is it normal for there to be three cases of multiple sclerosis on ONE street? Is there any possibility of environmental impact? I'm in Bitola, Macedonia. Thanks.
That would really depend on the number of at risk individuals in the area you describe, the age distribution of the population and if any of these individuals are/were related. Assuming the number is high, the next step is to confirm the diagnosis in each case. It is quite possible that only 1 or 2 of the cases actually have MS and this would not be unusual.
