<<Lyme Disease is acquired by the bite of a tick infected with bacteria of the genus Borrelia (which also cause Relapsing Fever). Those who work (or play) outdoors among vegetation – forestry and park workers, groundsmen, gardeners, farmworkers, railworkers etc. – are particularly at risk. Forests and rural areas are especially dangerous, but the presence of Lyme-carrying ticks has been documented even in London parks.>>
