Does a tick bite cause lyme disease
Lyme disease is transmitted following the bite of certain types of ticks if they have been infected with particular Borrelia bacteria.
Only some species of ticks are capable of being infected by the Borrelia bacteria and only these infected ticks can pass the infection on to humans. These ticks are commonly found in parts of Asia, Europe and North America. Related ticks occur in Australia but these have not been shown to be infected with Lyme disease Borrelia bacteria.
