"Hosting the launch of NIIMS is a great recognition and also a vote of confidence in our County and it's leadership . We do not take this noble gesture for granted.
"This is a great step in the right direction as we aspire to improve government services to members of the public," the governor conveyed.

Members of the public, including foreigners living in Kenya, have until mid-May to register with NIIMS and get their own unique identification number.
