Unusual features in the epidemiology of Lyme borreliosis

In this study two cases of Lyme borreliosis are presented. First, the author describes how he contracted Lyme borreliosis 24 hours after he visited an endemic area. The second case described is that of a woman who developed Lyme borreliosis symptoms, when intestinal content of an infected tick came into contact with her conjunctiva. In both cases the diagnosis is based on clinical picture and positive serological tests. The first case shows the probability of contracting Lyme borreliosis when the duration of the tick's attachment to the skin is less than 24 hours. The second case, described demonstrates transmission of B. burgdorferi by contact.
