The World Health Organisation (WHO) has announced that 44 instances of cholera have been documented in Tana River County, eastern Kenya.
"I believe that between government and national and international partners, we'll be able to contain it," the UN's resident coordinator in Kenya, Stephen Jackson, said in an interview with Citizen TV.
"We've contained cholera before, but it's a significant concern," he added.

Cholera is an acute intestinal illness that spreads by contaminated food and drink, resulting in severe diarrhea, vomiting, and muscular cramps.
"WHO will continue to support the health emergency response and remain vigilant for disease outbreaks that can easily spread if not quickly contained," Abdourahmane Diallo, WHO representative in Kenya, said in a statement issued by the UN's health agency on Tuesday about the 44 cases.
"We must be agile and ready to respond, led by government and along with the partners, to bring relief to hundreds and thousands of affected people," Diallo said.
The floods have killed at least 228 people, while thousands of others have been displaced across the country.
