How long must a tick generally be attached to transmit Lyme disease?

Answer

At least 24 to 48 hours

The transmission of the bacteria that causes Lyme disease is not instantaneous. A tick must remain attached to the host for a significant duration, typically 24 to 48 hours, for the pathogen to successfully transfer. This provides a window of opportunity to discover and remove a tick before infection can occur.
