Lyme disease, also known as Lyme infection, is a vector-borne disease reported in the United States of America and Europe. Lyme disease is caused by an infection that spreads by tick bytes – a bacterium called a "spirochete" is known as the agent of Lyme disease. Although the infection was first described in Europe approximately hundred years ago, it was only in 1975 when the full syndrome was identified.
