Retrospective Analysis of Potential Lyme Disease Clinical Cases in Argentina

Abstract

Lyme disease, a multisystemic infectious disorder caused by pathogenic spirochetes of the genus Borrelia transmitted by the bite of ticks, typically from the family Ixodidae, pose a significant public health issue worldwide. The Borrelia burgdorferi sensu lato (s.l.) group encompasses the Borrelia Lyme Group (LG), Borrelia Echidna-Reptile Group (REPG), and Borrelia Relapsing Fever Group (RFG), with some species remaining unclassified due to culturing challenges. Research into B. burgdorferi s.l. infection (Lyme Group) has intensified, focusing on its epidemiology, diagnosis, and treatment. Originally identified in North America and Europe, Lyme disease has now become a global concern, with Latin American countries reporting the microorganism, the disease, and/or its vectors. In Argentina, the presence of B. burgdorferi and Lyme disease has sparked significant scientific and medical debate. Ecological changes due to climate and habitat shifts have expanded the geographical distribution of these ticks. Argentina, with its diverse geography and climate, hosts various tick species that could potentially act as Lyme disease vectors, raising important public health questions. The confirmed presence of B. burgdorferi s.l. and Lyme disease in Argentina remains contentious but relevant, necessitating thorough scientific and medical examination. This work aims to enhance understanding and discussion of Lyme disease in Argentina by presenting clinical cases and their laboratory analyses, highlighting the disease’s presence and implications in the country. Through documenting suspected clinical cases and analyzing available data on B. burgdorferi and Lyme disease in Argentina, this study seeks to contribute to the understanding of the disease’s current status and inform future research, prevention, and control strategies in the region. The goal is to provide a basis for addressing Lyme disease’s public health impact in Argentina and promote further investigation into this evolving issue.
