Comparison of Lyme Disease in the United States and Europe

Emerg Infect Dis. 2021 Aug;27(8):2017-2024. doi: 10.3201/eid2708.204763.ABSTRACTLyme disease, or Lyme borreliosis, is the most common tickborne disease in the United States and Europe. In both locations, Ixodes species ticks transmit the Borrelia burgdorferi sensu lato bacteria species responsible for causing the infection. The diversity of Borrelia species that cause human infection is greater in Europe; the 2 B. burgdorferi s.l. species collectively responsible for most infections in Europe, B. afzelii and B. garinii, are not found in the United States, where most infections are caused by B. burgdorferi sensu stricto. Strain differences seem to explain some of the variation in the clinical manifestations of Lyme disease, which are both minor and substantive, between the United States and Europe. Future studies should attempt to delineate the specific virulence factors of the different species of B. burgdorferi s.l. responsible for these variations in clinical features.PMID:34286689 | DOI:10.3201/eid2708.204763

is the most common tick-borne illness in the USA and Europe. Pathogens involved include Borrelia burgdorferi in the USA and B. afzelii and B. garinii in Europe. The characteristic rash of erythema migrans occurs in 70 –80% of patients. Neurological disease, including facial palsy, meningo-encephalitis, aseptic meningitis and polyradiculopathy, occurs in 10–15%. Cardiac disease, primarily manifest as heart block, is seen in 1–4%. Arthritis is a late complication in about 30% of untreated patients.

Borrelia burgdorferi and Rickettsia conorii are microorganisms transmitted by ticks; infection with these bacteria result in a wide spectrum of manifestations on imaging. In areas where these tick-borne microorganisms are endemic, including Spain, these infections must be included in the differential diagnosis of patients with a variety of systemic and neurologic symptoms. The clinical presentation of these infections is nonspecific, and CT...
