Officials in Kenya’s Kakamega County are struggling to find the cause of a mysterious illness that has reportedly left 95 girls at a girl’s high school barely able to walk.

Over the past couple of weeks, 95 students from St. Theresa’s Eregi Girls High School in Kakamega, a city located 374 kilometers northwest of Nairobi have been hospitalized due to paralysis of the lower limbs, sparking concerns about a mysterious illness. The “epidemic” sparked panic and anxiety among parents, who demanded answers and protection for their daughters. Local media outlets reported that the girls are experiencing a condition that renders their legs numb and immobile, and clips that are doing the rounds on Kenyan social media show the girls struggling to walk properly.

Bernard Wesonga, Kakamega County’s CEC for Health, told journalists that blood, urine, and stool samples have been collected and sent for extensive testing to determine the cause of the unknown illness, but so far, the exact cause of the girls’ paralysis has not been established. Meanwhile, the school has reportedly been closed indefinitely.

The dozens of girls at St. Theresa’s Eregi Girls High School affected by the mysterious condition reported their legs feeling numb and immobile. Some of them also experienced severe headaches, vomiting, and fever. Luckily, many of them have already started getting better.

“Some students are responding positively to medication, while others are still under medical care,” Bernard Wesonga said.

The local government has urged parents to monitor their children closely while health officials work to identify the causes of the mysterious condition and establish measures of containment.
