Leptospirosis is a global spirochete causing chronic renal disease that is increasing in Costa Rica. This paper identifies the prevalence and risk factors of leptospirosis in Costa Rica between the years of 2011-2015.

Clinical cases of leptospirosis in Costa Rica demonstrated various symptoms: from asymptomatic diseases to severe cases of kidney and liver failure. A variety of diagnostic methods with varying specificities and sensitivities were employed. In Costa Rica, prevention methods such as protective clothing, decreased contact with animals, and prophylaxis of close contacts continue to be the most important factors in reducing transmission of leptospirosis.

In Costa Rica, the following populations should be aware of their increased risk: those living in the province of San José, Puntarenas, or Alajuela; being a male; being of productive years; and exposure to specific environmental factors.
