"An area that is of keen interest at the Fisher Center, however, is tick-borne illnesses, particularly Lyme disease, as there is some controversy over its diagnosis and treatment. Though the bacterium that leads to Lyme was first recognized in the early 1980s, breakthrough improvements in detecting the illness and treating its sufferers have been slow in coming. The center has recently started a retrospective analysis of the medical school's experiences with the tick disease, with an eye toward improving clinical practices and possibly determining if Lyme manifests itself differently in the Mid-Atlantic than in New England and Wisconsin, where it is much more prevalent."
