If a tick has attached itself to you, you need to remove it as soon as possible. Not all ticks carry Lyme disease, so
if you are bitten by a tick you may not be infected.

Transmission of
B. burgdorferi is
unlikely
to take place unless the tick has been in place for > 24 hours
[51].

Studies in laboratory animals have found that
transmission of Lyme disease usually requires the tick to be attached
for at least 48 hours, with the risk of infection being low if attachment is for less than 24 hours [Hytonen et al,
2008]
[71]. In a study investigating the risk of
B. burgdorferi
transmission in gerbils after different periods of feeding, all gerbils with ticks removed ≥ 47 hours
post-attachment
were found to be infected whilst 50% of gerbils were found to be infected 16.7 hours post-attachment
[51].
