Lyme Disease Endemic Regions: Europe, North America, and Asia Risk Areas
Lyme borreliosis (Borrelia burgdorferi sensu lato) is the most common vector-borne disease in the Northern Hemisphere, transmitted by Ixodes ticks.
Geographic Distribution
- Europe: Endemic in most countries; highest incidence in Central/Eastern Europe (Austria, Czechia, Germany, Slovenia, Baltic states, Scandinavia). UK: rising, especially Scotland.
- North America: Northeast, Mid-Atlantic, Upper Midwest (US); southeastern Canada (Nova Scotia, Quebec, Ontario, Manitoba). B. burgdorferi s.s. dominant.
- Asia: China (NE, NW), Japan (Hokkaido), Korea, Russia (Siberia, Far East), Mongolia. Species: B. garinii, B. afzelii, B. bavariensis.
Risk Modifiers
- Season: Peak nymphal activity May–July (highest human risk).
- Habitat: Deciduous woods, leaf litter, ecotones.
- Host density: White-footed mice (US), rodents/birds (Europe/Asia).
Prevention
- Permethrin-treated clothing, EPA-registered repellents (DEET ≥20%, picaridin, IR3535).
- Daily tick checks; prompt removal (<24 hrs attachment).
- Landscaping: barriers, deer fencing, acaricide treatment.
Post-exposure prophylaxis (doxycycline 200 mg single dose) if high-risk bite in endemic area.
