Five counties with some of the largest populations are still lagging in Social Health Insurance Fund (SHIF) registrations.
The regions – Garissa, Turkana, Mandera, Wajir and West Pokot – also happen to carry a large health burden.
The latest government data also reveals the top five counties with the highest registrations.
These are Nyeri, Kirinyaga, Kiambu, Lamu, and Embu.
Health Cabinet Secretary Dr Deborah Barasa called on Kenyans to register.
“Be part of your county’s health success,” she said.
Bottom five
The bottom five counties by the percentage of the population registered shows that Garissa has recorded just 20,674 people against a target of 905,000, about 2.3 per cent.
The report also shows that Turkana has 27,840 people registered out of 926,976 targeted, about 3 per cent; while Mandera has 29,529 against a target of 867,457 or 3.4 per cent.
