Le résumé fourni par la source

Background: Leptospirosis is a significant zoonotic infection caused by Leptospira spirochetes, which are distributed globally. Infection typically occurs through exposure to water or soil contaminated by the urine of mammals, including dogs, cattle, pigs, or rodents. Objectives: The objective of this study was to elucidate the epidemiological, clinical, and laboratory characteristics of leptospirosis cases in Turkey. Methods: In a retrospective review, we analyzed the clinical and laboratory data of all individuals under 18 years diagnosed with leptospirosis at a secondary care center in Southeast Turkey from the beginning of 2020 to the end of 2022. Results: Over the two-year period, 36 confirmed cases of leptospirosis in individuals under 18 were identified. All patients had been engaged in activities at wells in cornfields, assisting their families with irrigation or related to well operations. Of these patients, 3 (8%) resided in urban areas, while 33 (92%) lived in rural settings. None required intensive care, and there were no fatalities reported. The most common symptoms at presentation were fatigue (83%), fever (75%), and nausea/vomiting (75%). Laboratory tests revealed that all patients had positive C-reactive protein (CRP) levels, with a significant portion (61%) showing highly positive results (CRP > 100). Conclusions: In conclusion, leptospirosis should be considered by clinicians when evaluating patients, especially those with risk factors like occupational exposure. Prompt testing for the disease is advisable under these circumstances.
