The Ministry of Health (MoH) has issued five advisories following an outbreak of a mysterious illness in the South Mugirango Constituency, Kisii County.
As of Tuesday, March 4, the MoH has confirmed 61 cases and reports that the illness has affected over 200 residents in villages such as Nyabigege, Nyamarondo, and Nyarigiro.
“The Ministry of Health has been alerted about an outbreak of an illness with symptoms including diarrhea, fever, abdominal pain, and headaches in Amarondo, Nyabigege, and Nyangiro villages, South Mugirango Sub-County, Kisii County,” the statement noted.
The MoH has activated a rapid response team that is currently conducting case listing, contact tracing, and active case finding to contain the outbreak.
Initial tests suggest that the source of the infection is a contaminated spring, which serves as the primary water source for the affected areas.
“Laboratory results have confirmed the presence of bacteria typically found in human or animal fecal matter, making the water unsafe for consumption unless properly treated,” the statement added.
“Further laboratory analysis of stool samples from affected patients is ongoing to identify the specific causative agent.”
As a result, the government has closed the contaminated spring and urged residents to refrain from using it.
“We have confirmed that the water from the spring is contaminated and advise people to stop consuming it immediately,” said Muthoni, a Ministry spokesperson. “Please seek alternative water sources.”

To prevent further spread of the disease, the Ministry has issued the following five preventive measures:
- Ensure drinking water is safe – Always boil water or use chlorine-based water treatment before consumption.
- Store drinking water properly – Keep water in clean, covered containers to avoid contamination.
- Practice good hand hygiene – Wash hands frequently with soap and clean water, especially before eating and after using the toilet.
- Use proper sanitation facilities – Use well-constructed toilets or pit latrines to prevent contamination of water sources.
- Seek immediate medical attention – Visit the nearest health facility if you or anyone in your household develops symptoms.
The Ministry of Health, in partnership with county health officials and other stakeholders, is taking urgent action to manage the outbreak, including enhancing public health education, water treatment interventions, and ongoing surveillance.
“We are committed to identifying the exact cause of this outbreak and implementing measures to prevent further spread, ensuring the health and safety of all affected communities,” the statement concluded.
Meanwhile, the World Health Organization (WHO) sent a team to South Mugirango on Monday, March 3, to assess laboratory capacity, assist in disease identification, and strengthen coordination and response efforts.
Patients with the illness have been admitted to Tabaka Mission Hospital, Nyatike Level Two Hospital, and various private health facilities.
Symptoms reported by patients include severe diarrhea with bloody stools, fever, fatigue, and intense headaches.
