There are fears that the number of sick people could be higher and will likely affect other counties as some of the guests came from Mombasa and Eldoret.
Tana River and Dadaab in Garissa have confirmed cholera cases while Murang’a, a cholera hotspot, is being monitored closely for possible outbreaks.
The Karen newlyweds, who wished to remain anonymous, cut short their honeymoon in Mombasa on Thursday and flew back to Nairobi to visit their ailing relatives and friends.
Nairobi County executive committee member for health Bernard Muia confirmed the cases but denied there were any deaths related to the disease.
He said the reported cases involve people who came to the city from elsewhere.
“I am advised by the county disease surveillance team that the patients admitted to Nairobi hospitals came from western Kenya,” he said.
But this may not be the case, as a visiting German man, Alex Wolf, who attended the wedding alongside his Kenyan girlfriend, was being treated in isolation at Nairobi Hospital for the disease, which has affected his kidneys.
Family members who spoke to the Nation suspect their woes came from the food they ate at the ceremony.
There are sketchy details about the hired cateress, who on Thursday refused to comment on the matter.
However, sources close to the company intimated to this newspaper that one of the people who served food at the wedding had been unwell with a stomach infection.
Eric Kibe, the programme director at SafiServe, an organisation that trains food service workers on how to protect consumers from food-borne risks, said Kenyans need to be careful about who makes their meals.
“We are all food consumers and if you bring a caterer to your event, make sure that you have proof of their well-being,” he said.
“Do they have a food handling certificate, for instance? This certificate expires every six months, therefore, you should watch out for this."
