Reports indicate that 57 of the over 400 police officers deployed to secure the Supreme Court last week have been hospitalised following a cholera outbreak.
The 57 officers were on Sunday admitted in various hospitals within the city after they were found to have contracted the fatal infection.
The 430 officers had been outsourced from various parts of the country and were being accommodated at the Multimedia University (MMU) in Ongata Rongai.
In a statement to newsrooms, Nairobi Governor Mike Sonko confirmed that 10 of the officers housed at MMU had been taken ill with "severe abdominal pain and diarrhoea".
"They have been admitted at the Sinai Hospital...Rapid diagnostic tests for cholera have been done on the 10 and found positive.
"All are quarantined in the said hospital awaiting confirmatory tests," Governor Sonko's statement read in part.
The Administrator of Sinai Hospital in Rongai Estate, Dr Paul Dullo, told journalists that his facility had admitted 25 of the sick officers.
He, however, conveyed that they were still under observation and cholera was yet to be confirmed.
"They show symptoms of normal fever, diarrhoea in a few cases and that type of thing so we are trying to check what is causing all that," Mr Dullo told NTV.
The source of the infection is yet to be identified according to Nairobi Head of Disease Surveillance Mr Raphael Muli.
"We cannot state that this (MMU) is the source because out of the 430 who were here, if this is the source then we'd have many more cases. They used to have breakfast and supper here and ate lunch elsewhere," Muli stated.
The official added that 12 other cases had been confirmed at the Kenyatta National Hospital, 2 at Nairobi West Hospital and 20 more at the Nairobi Women's Hospital in Rongai.
