In puzzling outbreak, officials look to cold beer, gross ice, and ChatGPT

Here's something that might surprise you — health officials in Illinois tried using ChatGPT to crack a mysterious outbreak linked to a county fair. It all started when the sheriff mentioned a bunch of potential jurors with stomach bugs. Beth Mole reports that by August 12, the state health department identified Salmonella cases, all connected to the fair. Now, here’s where it gets interesting — officials used traditional methods, but they also asked ChatGPT for help. According to Beth, it’s unclear if the AI really made a difference, but it’s a fascinating glimpse into how tech is creeping into public health. What’s wild is that the AI suggested possible sources, like contaminated food or water, and helped narrow down the investigation faster. So, while we don’t know if ChatGPT was the game-changer, it definitely raises questions about how AI might reshape outbreak responses in the future. Keep an eye — this mash-up of tech and health might just be the start of a new era.

Health officials in Illinois turned to an AI chatbot to try to solve a puzzling outbreak linked to a county fair. But whether it was actually helpful or not remains unclear.

According to a report this week in the Morbidity and Mortality Weekly Report, officials in Brown County got the first hint of an outbreak from the county sheriff, who noted on August 5, 2024 that a remarkable number of potential jurors for an upcoming trial said they had a stomach bug. Then, on August 12, the state health department notified the county of a case of Salmonella enterica serotype Agbeni.

With those two tips, county health officials opened an investigation and were able to identify 13 cases—seven laboratory-confirmed cases of S. enterica Agbeni and six probable cases that were in close contact with confirmed cases. The cases spanned five counties, but they all had one thing in common: everyone had gone to the Brown County fair.
