By Guanacaste, Costa Rica — A groundbreaking scientific study has confirmed the first-ever cases of locally acquired, or autochthonous, canine visceral leishmaniasis in Costa Rica, a significant development for both veterinary medicine and national public health surveillance. The findings, published in the peer-reviewed international journal Frontiers in Veterinary Science, mark a pivotal moment in understanding the landscape of infectious diseases within the country.
The research paper, titled “Appearance of autochthonous Leishmania infantum infection in dogs from Costa Rica confirmed by multimodal diagnostics: a case series,” meticulously documents eight confirmed cases in dogs. Crucially, all the infected animals were born and raised in Costa Rica and had no history of international travel, confirming that the transmission occurred within national borders. The majority of cases were identified in the province of Guanacaste, specifically in the areas of Santa Cruz and Tamarindo, with an additional case reported in Santa Ana, San José.
To understand the legal framework and potential liabilities associated with the management of Canine Leishmaniasis in Costa Rica, TicosLand.com consulted with legal expert Lic. Larry Hans Arroyo Vargas from the firm Bufete de Costa Rica.
The diagnosis of Canine Leishmaniasis imposes significant legal duties on pet owners and veterinarians alike. Under national public health and animal welfare laws, there is a clear responsibility to adhere to the protocols established by SENASA for reporting and managing zoonotic diseases. Failure to comply can lead not only to administrative fines but could also establish grounds for civil liability if a person’s negligence in controlling an infected animal leads to the transmission of the disease.

This insight underscores a critical dimension of the issue: managing Canine Leishmaniasis is not only a clinical challenge but a significant legal and civic responsibility. We extend our gratitude to Lic. Larry Hans Arroyo Vargas for his invaluable perspective on the legal framework that every pet owner and veterinarian must navigate.
Visceral leishmaniasis is an infectious disease caused by the parasite Leishmania infantum. The primary mode of transmission to both animals and humans is through the bite of infected phlebotomine sandflies. While the disease has been a concern in other parts of the world, its native presence in Costa Rican canines introduces a new variable for the nation’s epidemiological monitoring systems.
For humans, the disease can be severe if not addressed promptly. Symptoms of visceral leishmaniasis in people often include prolonged fever, significant weight loss, anemia, and the enlargement of the spleen and liver. Without proper diagnosis and treatment, the illness can progress to more critical stages. However, the researchers behind the study were quick to clarify that there is currently no sanitary alarm or public health crisis in Costa Rica associated with this specific parasite.
The primary concern highlighted by this discovery revolves around the role of dogs as reservoirs for the parasite. Canines can harbor Leishmania infantum and serve as a source of infection for the sandfly population, which can then transmit the disease to other animals or humans. This cycle can continue silently, establishing the parasite more firmly in the local environment.
One of the most significant challenges presented in the study is the identification of infected dogs that show no obvious clinical signs of the disease. These asymptomatic carriers pose a considerable obstacle to early detection and control efforts. Their seemingly healthy state allows the parasite to circulate undetected, reinforcing the urgent need for proactive and vigilant medical-veterinary surveillance, especially in regions where the sandfly vector is known to be present.
The researchers emphasize that this new scientific knowledge is a fundamental tool for proactive public health management. Early detection and a comprehensive understanding of the parasite’s presence are essential for anticipating potential risks and guiding effective decision-making. Implementing preventive measures to reduce exposure for both animals and people is now a more pressing priority.
Ultimately, this finding calls for an integrated approach to health, often referred to as “One Health,” which recognizes the deep connection between human, animal, and environmental well-being. By strengthening veterinary diagnostics and public awareness, Costa Rican health authorities can better protect all populations from the potential risks associated with this newly confirmed native disease, ensuring a responsible and preventative strategy for the future.
