A cholera outbreak has been reported in Vihiga, a day after Nairobi was put on red alert following the deaths of three people in the city.
One person has succumbed to the water-borne disease in the western Kenya county, according to director of health Quido Ahindukha.
Two others, Dr Ahindukha said on Friday, were treated and discharged from Kaimosi, the county referral hospital.
The outbreak, the first in the region since July last year, was first reported on Monday.
He said the deceased was diagnosed in Nairobi and then travelled to Vihiga before his condition worsened.
"He was rushed to Kaimosi Hospital, where he succumbed to the disease,” said Dr Ahindukha.
The county has also dispatched a health surveillance team to Kaimosi, Chango and Kigama “because these are the areas where people who travelled to Nairobi for a wedding hail from.”
“Some of them have returned and so we must be on high alert," said Dr Ahindukha.
Nairobi was on Thursday evening put on high alert after three people, who all met and ate at a wedding in Karen on Saturday, died of cholera.
Five others, including a foreigner, are being treated at various hospitals in the city.
The victims and patients were part of a larger group of about 400 guests who had attended the garden wedding in the area.
Food had been supplied by an outsourced caterer.
