Former President Daniel Arap Moi was on Wednesday afternoon admitted at Nairobi Hospital where he will undergo a routine medical check-up.
His physician Dr David Silverstein stated the former president will spend a couple of nights in the hospital to accord the doctors enough time to carry out their investigations.
Earlier in the year, Moi flew to Israel for a checkup after developing complications in his knee causing him discomfort.
His son, Baringo Senator Gideon Moi asked Kenyans to pray for Mzee Moi as he went out for the medical checkup.
According to Dr. Silverstein, the visit to Israel was meant to seek a second opinion on the knee problem.
The former president who has enjoyed good health since leaving office 2002 allegedly developed the knee problem after his car was involved in a head-on collision on July 30, 2006 at Rukuma View Point, Limuru.
He was hospitalized shortly at Nairobi Hospital after the accident that involved his Range Rover and a Nissan Pick-up.
Mzee Moi underwent a knee surgery in January 2017 at Aga Khan Hospital, Nairobi.
This surgery was reportedly the first time that the retired president was admitted to the hospital using his real name, having previously used pseudo names to avoid attracting attention.
Several leaders have called on Mzee Moi at his Kabarak home where has been recovering since the procedure in Israel.
President Uhuru Kenyatta, ODM Leader Raila Odinga, Mombasa Governor Hassan Joho, Wiper Leader Kalonzo Musyoka have made a trip to Kabarak.
