Kirinyaga Governor Anne Waiguru Thursday said the county had handled its first Covid-19 case.
The patient, a truck driver, was traced to a maize factory in Kutus which was closed for four days after being fumigated.
The 55-year-old had delivered maize from Malaba in Busia County. He was taken to Kenyatta University Hospital in Nairobi.
Two factory workers were isolated at Kerugoya for testing and 22 others put in self quarantine.
