Introduction: Lyme disease is caused by an infection with
Borrelia burgdorferi sensu latu (B. burgdorferi sl.) which is carried
by Ixodes ticks. The disease has not been considered to be
endemic in Iceland and no cases of Icelandic origin have been
published. The epidemiology of Lyme disease in Iceland has
never been studied. The objective of this study was to provide
basic epidemiological information about Lyme disease in Iceland.
Material and methods: Included in the study were all pa -
tients who had a measurement of serum antibodies against B.
burgdorferi sl. or were diagnosed with Lyme disease (ICD-10,
A69.2) at Landspítali University Hospital in Iceland from 2011-
2015. Clinical data regarding these patients was retrospectively
collected from medical records and the database of the Depart-
ment of clinical microbiology at Landspítali University Hospital.
Results: 501 patient had a measurement of serum antibodies
against B. burgdorferi sl. and 11 patients were clinically diag-
nosed with Lyme disease during the study period. 33 patients
fulfilled criteria for a confirmed diagnosis of Lyme disease. 32
(97%) patients had erythema migrans and one (3%) patient had
neuroborreliosis. An average of 6.6 cases were diagnosed a
year (two cases per 100,000 persons/year). All cases originated
abroad.
Conclusions: Lyme disease is rare in Iceland. On average around
6 to 7 cases are diagnosed every year, primarily localised infec-
tions presenting as erythema migrans. None of the cases had a
definitive Icelandic origin and the yearly number of cases has not
been increasing.
