In North Carolina, more than any other state, the recession has triggered a burgeoning medical crisis. A steep rise in unemployment has fueled a commensurate increase in the number of people who do not have health insurance. In the past two years, North Carolina's number of uninsured has climbed 22.5%, the biggest jump in the nation, according to an analysis by the North Carolina Institute of Medicine, a quasi-state agency. Nationwide, about 22% of adults do not have health insurance.
