Mystery paralysing 'illness' that left 100 girls in Kenya unable to walk and convulsing was triggered by mass hysteria, officials say

Dozens of girls in Kenya supposedly sickened by a paralysing 'illness' fell victim to hysteria, authorities have claimed.

More than 100 students were suddenly struck down last week at an all-girls school in Musoli, 232 miles (374km) north west of Nairobi.

Bed-bound children were also seen convulsing in what appeared to be a hospital in clips claiming to show the extent of the crisis. 

But local officials have now said the mystery spate of cases was actually triggered by hysteria. They blamed pupils' anxiety over upcoming end of year exams.
