[The classification of Lyme borreliosis (Lyme disease)].

A new version of Lyme's disease classification based on the authors' experience and other classifications is proposed. It distinguishes periods of the disease (acute, subacute, chronic) and stages (I--isolated erythema migrans, II--local disseminated infection, III--generalized disseminated infection) as well as the signs which are significant in Lyme's disease diagnosis: erythematous and nonerythematous form, seropositivity or seronegativity against Borrelia burgdorferi. Subclinical (latent) infection, complications of Lyme's disease (fibromyalgia syndrome, chronic fatigue syndrome, etc.) and mixed-infection with tick-borne viral encephalitis are included as well.
