He encouraged the community to register for the Social Health Authority (SHA) scheme to benefit from universal health coverage, which is now being rolled out nationwide.
On matters of politics, the CS hit at the opposition, accusing its leaders of perpetuating tribal politics and selfish interests.
He specifically faulted opposition leaders, claiming they had failed to deliver when in power and are now misleading Kenyans for political gain.
"Kenya is a unitary state. We must remain united and focused on development, not distracted by leaders who thrive on division and past failures," he said.
His visit comes amid growing efforts by the government to respond more swiftly to emergencies and push forward its affordable housing and healthcare agenda.
