In Chuka Sub-county, Tharaka Nithi County, Mukuuni Boys' High School has been shut down due to an outbreak of a disease exhibiting symptoms similar to those of cholera.
The County Director of Education, Bridget Wambua, has confirmed the incident, stating that over 40 students have been taken to Chuka County Referral Hospital and Chuka Nursing Home with stomach pains, diarrhea, and vomiting.
