Chicago’s Morning Answer hosts Amy Jacobson and Jim Iuorio, filling in for Dan Proft, welcomed Dr. Ron Elfenbein, an emergency medicine physician and former urgent care medical director in Maryland, to discuss a multistate cyclosporiasis outbreak that has drawn national news coverage, along with growing scrutiny of Senator Lindsey Graham’s fatal aortic dissection. The hosts referenced a national news segment reporting more than two hundred cases in Illinois and outbreaks across three dozen states, with Michigan identified as a particular hot spot, and some reporting linking the illness to bagged lettuce and prompting Taco Bell to voluntarily pull certain ingredients.
Elfenbein said cyclosporiasis is a parasitic illness contracted through contaminated food rather than person-to-person contact, and cautioned against the level of alarm surrounding recent coverage. He said the infection can cause prolonged, uncomfortable diarrheal symptoms lasting weeks rather than days, but is rarely fatal outside of immunocompromised patients and is treatable with a sulfa-based antibiotic. He advised that diarrhea lasting more than a week, or accompanied by blood or mucus, warrants medical attention, while shorter episodes typically resolve on their own and don’t require contacting a local health department, though he noted that reporting persistent cases can help public health officials trace outbreaks back to their source.
Asked whether pandemic-era mistrust of public health guidance is a net positive or negative, Elfenbein said healthy skepticism and independent thinking are valuable, but argued that the erosion of institutional trust during COVID has had lasting consequences for how patients relate to physicians generally, including those who did not spread misinformation themselves.
The conversation turned to the death of Senator Lindsey Graham from an aortic dissection, with Jacobson noting Graham’s family history of cardiovascular disease, including his father’s fatal heart attack at a young age. Elfenbein explained that aortic dissections are notoriously difficult to diagnose because their symptoms, including back, abdominal, or chest pain, frequently mimic other conditions such as a heart attack. He described the underlying physiology, in which a tear in the innermost layer of the aorta allows blood to enter between the vessel’s muscular layers rather than flowing normally, and said a full rupture can be fatal within roughly thirty seconds due to rapid blood loss. He said prompt treatment focuses on aggressively lowering blood pressure to reduce stress on the vessel wall, with some cases requiring emergency surgery depending on which section of the aorta is affected.
Elfenbein said uncontrolled high blood pressure remains the leading risk factor for aortic dissection and that regular exercise meaningfully reduces risk by helping keep blood pressure in check. He noted that imaging such as a CT or MRI scan can detect small tears or areas of concern before they become life-threatening, allowing physicians to monitor patients over time. When asked about circulating theories connecting the timing of Graham’s death to public threats attributed to Iranian officials, Elfenbein said he could not speak to any connection, but noted that Graham’s known risk factors alone would have made him a candidate for the condition regardless of any external circumstances.
Elfenbein closed by discussing his own ongoing legal case, in which federal healthcare fraud charges against him were dismissed by Maryland’s chief federal judge in a lengthy written opinion finding no evidence of wrongdoing, only for the case to be revived on appeal. Elfenbein said he believes the prosecution originated in retaliation for his public commentary criticizing the Biden administration’s handling of monoclonal antibody treatments during the pandemic, and said he now faces a second trial over what he described as an underlying billing dispute worth a few hundred dollars, with a potential sentence of decades in prison.
