We had two friends who had it. It is also called French Polio. One got it after the Swine flu vaccination which they had to have for their job. Another after being very stressed and sick. The first person recovered quite nicely. The second one not totally recovered. Lasting effects for that one. Could only move the eyes at the lowest point.
