Lyme disease (LD) is a naturally occurring disease mainly caused by Borrelia burgdorferi. This problem has been of outstanding importance since 2017, as Western Ukraine, particularly the Ternopil region, is a territory endemic of Lyme borreliosis.
The insufficient consideration of the epidemiological history, the epidemic history, and the hereditary and allergic history of a patient leads to an erroneous diagnosis and possible mistakes in the treatment. Pediatric providers in the endemic regions, especially those working in hospitals, must be thus familiar with the clinical presentation and must have a high index of suspicion for LD in order to prevent mismanagement [1,2].
