Two Neonates With Postnatally Acquired Tickborne Infections

Pediatrics. 2019 Dec;144(6):e20191937. doi: 10.1542/peds.2019-1937.

Abstract

Neonatal tick bites place infants at risk for acquiring infections that have rarely or never been documented in this age group. We describe 2 rare cases of tickborne infection in neonates. The first patient presented with multiple erythema migrans and fever, leading to a diagnosis of early disseminated Lyme disease. The second patient presented with irritability, fever, and worsening anemia due to babesiosis. Both infants had been bitten by arthropods fitting the description of ticks before the onset of symptoms. Our cases demonstrate the clinical course of 2 common tickborne infections occurring at an atypical age, opening the door to new, complex questions for which little guiding data exists. As tickborne infections become more prevalent, we expect other clinicians will be faced with similarly challenging neonatal cases. Providers must use past experience and a keen eye to identify neonates with tickborne infections and sort through their optimal diagnosis and management. In this article, we raise some of the questions we faced and discuss our conclusions.
