Dr Ouko, was a lecturer at the University of Nairobi.
John Orindi, UoN communications director said the lecturer died on Saturday at the Aga Khan Hospital in Nairobi.
Education Cabinet Secretary George Magoha mourned Dr Ouko as one of the most intelligent lecturers in the sociology department.
Prof Magoha said his death demystifies the notion that Covid-19 only affects the elderly.
“He was much younger than me and it is sad that we have lost such a vibrant young man to the virus,” he said.
UoN vice Chancellor Prof Stephen Kiama said the lecturer’s death is a huge loss to the university.
Kiama said so far UoN has lost four dependable staffers saying it is very painful to mentor brains, only to lose them when you need them most.
