Leptospirosis is probably the most widespread and prevalent zoonotic disease in the world. It is difficult to diagnose both in the clinic and the laboratory. Therefore, the disease is frequently not recognized and consequently severely neglected. Leptospirosis is (re-)emerging globally and numerous outbreaks have occurred worldwide during the past decade. Leptospirosis affects humans in rural and urban settings and in industrialized and developing countries. The most recent examples are the epidemics in Nicaragua in 2007, in Sri Lanka in 2008 and in the Philippines in 2009, each affecting several thousands of people and causing hundreds of deaths. Based on global data collection 300,000
Serology plays an important role in the diagnosis of leptospirosis. Few laboratories have the resources and expertise to perform the microscopic agglutination test and leptospirosis remains a neglected disease because of limited access to diagnosis, due to reliance on antiquated standard methods and the cost of commercially available alternatives. There is a need for rapid and simple serological tests which facilitate the early diagnosis of leptospirosis, while antibiotic therapy may be most effective. In Morocco this disease is little known. Studies about it are very rare. In this study 11 serums which referred to the National Institute of Health in Rabat, Morocco during 1-1-2014 to 30-6-2015 were evaluated by IgM ELISA and Slide agglutination test (SAT). 7 serums were positives by Elisa and 10 were positives by (SAT). 9 of cases were from Sidi kecem region. All patients were male. The rate of age for all patients was 29.5 years.
