Wiper leader Kalonzo Musyoka's motorcade was stopped by health workers in Kisii County as he drove to Kitutu Chache South during his second day tour.
The health workers had earlier on pitched camp at the Governor's office demanding that he addresses them.
Muysoka accused President Uhuru Kenyatta for failing to address challenges facing the health sector and warned that the country could plunge into unprecedented health crisis.
"Jubilee should do its job. They cannot go without even giving a solution to what we are facing. We need an urgent solution to this madeness," he told the agitated workers.
"We are punishing innocent people and this must end immediately. I am urging the president to cheap in and help us solve this issue once and for all," he said.
Musyoka is set to tour several regions in Nyamira County where he will urge locals to register as voters in the ongoing mass voter registration.
