Naivasha residents are living in fear after a fifth case of cholera was reported in the town on Friday.
The group blamed the Nakuru county government for failing to fund efforts towards eradicating the disease.
A number of community health workers (CHW) said there is no goodwill and support from the county government in fighting the outbreak.
The first case was reported last week.
In the latest case, a minor from Kihoto estate, which is home to hundreds of flower farm workers, was admitted to the Naivasha sub-county.
A health worker said that the four-year-old has been placed in an isolation ward.
