Lyme disease

Patent Pending Lyme disease, also known as Lyme borreliosis, is an infectious disease caused by bacteria of the Borrelia type.[1] The most common sign of infection is an expanding area of redness, known as erythema migrans, that begins at the site of a tick bite about a week after it has occurred. The rash is typically neither itchy nor painful. About 25% of people do not develop a rash.
