This number already matches the typical annual caseload, with state-level reports outpacing official CDC data, revealing the severity of the situation. ## Diagnostic challenges Most people endure a few days of watery diarrhea at home without seeking medical attention. Even those who visit doctors often skip the costly cyclosporiasis test, suggesting the actual case count far exceeds official figures. ## Source of contamination The outbreak is believed to spread through contaminated food. However, inadequate information sharing by federal authorities hampers efforts to identify the source and contain the spread effectively. ## Epidemiologist's insight Epidemiologist Katelyn Jetelina analyzed state data to uncover the outbreak's true scale amid limited federal reporting. Her findings highlight the gap between official statements and ground reality. ## Economic impact Thousands falling ill leads to significant workforce productivity losses. Effective tracking mechanisms are urgently needed to curb the outbreak and reduce strain on healthcare systems. ## Public health advisory Experts urge those with prolonged diarrhea symptoms to consult doctors and get tested. Adhering to hygiene practices and avoiding suspicious food items plays a crucial role in preventing further spread. ## Sources covering this story - https://flowingdata.com/2026/07/17/exploding-cyclosporiasis-outbreak/ — --- _Summary written by Brifing from the original reporting.
