“ Keep in mind, that Lyme seldom infects with a tick thats only been attached for under 24 hours so you are probably in the clear“
I wouldn’t say they are in the clear
“https://canlyme.com/2018/09/27/lyme-disease-can-be-transmitted-from-tick-in-12-hours-new-research-shows/“
yep - whilst its true that the longer a tick is attached the more chance it has of transmitting lyme - this is a general rule and assumes the tick has not bitten anything else in the recent past
before more was known about
ticks this seemed like a fair general assumption in that, on the whole, the ticks lifestyle is to go long periods without meals - often only taking one meal then drop off the host and moult from lava to nymph or nymph to adult.
however, as in many things in nature, this is not a hard and fast rule - and more recent studies have found that ticks are actually far more likely to take partial meals and bite multiple hosts if they are infected with borrelia - and that the borrelia are actually modifying the ticks behaviour
in this way to aid their transmission and survival.
the borrelia inside a tick will not have migrated into the gut or transformed into dormant states if the tick only just took a partial blood meal from another infected host - and so in theory transmission is possible almost instantaneously - its just less likely.
its not well researched - but other biting arthropods and insects likely transmit lyme also - these other arthropods have different lifecycles to ticks - and its not yet clear how this relates to the chances of them infecting new hosts - but they do typically bite more often than ticks and typically bite more hosts in succession so there could be a mechanism their that avoids the need to them to be attached for hours or days.
there are two documented instances in the scientific literature of horse flies transmitting lyme disease in humans - one by a medical doctor who was infected and had a bulls eye rash at the bite site.
