99 students and four teachers at Muruku secondary school in Laikipia County have tested positive for Covid-19.
The number is the highest to be recorded in a learning institution in Kenya.
According to Laikipia county Chief officer of health Dr Donald Moghoi, the cases were confirmed from 264 samples tested at the school last Friday after a number of students started showing coronavirus related symptoms.
Those affected have since been quarantined at the institution under the care of Ministry of Health officials.
Of the 99 cases, 40 are male while 59 are female. Dr Moghoi said all of the 17 teachers who were tested, three are female and one male who are currently receiving treatment at Ol jabet and Benedict Catholic hospitals in Nyahururu respectively.
Learning for other students at the institution is still going on. Most schools are administering third term exams and are set to close this Friday, according to the school calendar issued by the Ministry of Education.
Since the pandemic struck the country last year, several schools have been affected, with some being closed indefinitely as others put their students, teachers and workers under quarantine.
Kenya continues to record more COVID-19 positive cases in recent weeks, with experts warning of a looming fourth wave.
But the ministry of education insists that children are safe in schools and that learning will go uninterrupted.
As of Monday, June 12, the country’s caseload stood at 188,942 after 188 new cases were reported.
The positivity rate is now 8.0% while cumulative tests so far conducted are 2,018,013.
