It shows a strong seasonality, with epidemic potential especially after heavy rainfall. A recent systematic review by Costa et al. (2015) places leptospirosis among the leading zoonotic causes of morbidity and mortality worldwide, with 1.03 million cases and 58,900 deaths each year.\n\nLeptospirosis is an important public health problem, particularly within economically vulnerable populations. It is also emerging as a health threat in new settings due to globalization and climate change. Disasters and extreme weather events are recognized to precipitate epidemics.\n\nClinical manifestations are highly polymorphic, ranging from an anicteric, influenza-like form to severe forms with hepato-renal or pulmonary failures which are associated with high mortality.\n\nAntibiotic therapy should be prescribed early, as soon as leptospirosis is suspected and preferably within the first 5 days, before leptospira spread to the tissues. In the treatment of mild forms, usual antibiotics are oral amoxicillin or doxycycline for a standard treatment duration of 7 days. In hospitalized cases of leptospirosis, parenteral antibiotic therapy with ceftriaxone is often favored as first-line therapy.\n\nThe most widely used antibiotics in the French Caribbean and Indian Ocean regions are amoxicillin, doxycyclin and third generation cephalosporins such as ceftriaxone.\n\nResearch hypothesis:\n\nThe effects of shorter antibiotic therapy periods for other infectious diseases have been explored by several authors. The efficacy of short ceftriaxone treatment has been highlighted for typhoid fever or meningococcal meningitis. In a retrospective series of 21 cases, the interest of short treatment periods (3-6 days) for mild and severe leptospirosis has also been described. A minimal 3-day therapy period would seem necessary in order to biologically confirm leptospirosis diagnosis and to rule out other community-acquired infections.\n\nOur study proposal is the conduct of a non-inferiority trial comparing a shortened antibiotic therapy period of 3 days with the standard treatment period of 7 days in patients with mild leptospirosis and seen at the hospital in 5 French overseas departments (Martinique, Guadeloupe, French Guiana, Reunion, Mayotte).\n\nOriginality and innovative aspects:\n\nTo our knowledge, the efficacy of a 3-day antibiotic therapy for mild leptospirosis, as compared to the standard 7 day period, has not yet been explored.\n\nIn addition, the LEPTO3 study will be among the first clinical trials to focus on the endemic public health problem, which is leptospirosis, at a large geographical level (Caribbean and Indian Ocean regions) and to involve a high level of collaboration between medical and scientific teams of these territories.\n\nMain objective :\n\nCompare the efficacy of a 3-day antibiotic therapy period with the standard period of 7 days in mild leptospirosis patients seen at the hospital in 5 French overseas departments (Martinique, Guadeloupe, French Guiana, Reunion, Mayotte)\n\nSecondary objectives :\n\n* Compare the evolution of clinical and biological characteristics in the 2 groups of patients (antibiotic therapy duration 3 days versus 7 days)\n* Compare lengths of hospital stay in the 2 groups of patients (antibiotic therapy duration 3 days versus 7 days)\n* Examine factors linked to a potential treatment failure in patients\n* Assess patient tolerance to treatment",[72,78],{"label":73,"type":74,"description":75,"interventionNames":76},"3 days of
