This understanding will age like milk.

I’ve hear stats as long as 24 hours and as short as 30 seconds. One nurse told me that removing ticks by grasping and pulling means they transmit immediately, because you squeeze their contents through their mouths. I no longer believe any of the stats; seems like it could be at any time.

Unfortunately there are a number of tick-borne illnesses. Eg, Powassan virus is a viral infection that attacks the central nervous system (leading to encephalitis). It can be transmitted within hours or even just 15 minutes of tick attachment.

Another is Alpha Gal. It is a molecule carried in tick saliva that can cause serious allergies to red meat and even dairy. Because the molecule is in the saliva, it can be delivered immediately.

This is very helpful for determining if prophylactic treatment is necessary after discovering a tick.

If someone doesn’t notice a tick then they aren’t going to be considering prophylactic treatment anyway. It’s for the cases where ticks are discovered.

According to the dutch public health institute, the longer the tick is in the body, the bigger the chance of transmission. Early removal also does not prevent lyme, it just reduces the chances.

Next to that, in The Netherlands we have a site to report tick bites and if they had lyme disease or not. It’s good to know if you should be extra vigilant after a bite from a certain area. I think the self-test could be very useful for such sites.

This is one of the things that is oft repeated by my vector disease colleagues -- your infection may not be caused by the tick you found, but by the tick you didn't.

I think it's super helpful. Sure it doesn't help with ticks, you don't find, but in my experience it starts to itch eventually even with the tick attached. If it's negative good, if it's positive go see a doctor.

there have been times in my life where this could have saved me a doctors visit, and that's good enough for me

I think you need to stop overthinking. Yes it can make you sick, but the only thing you can do is be on the lookout for it and be smart about avoiding it. I've had around 4-5 ticks in the last years, my kids and family probably around 15-20, one recently near my ankle that probably could've been avoided if I wasn't wearing short trousers. But anyway nobody ever got sick from it and we live in a region with a high prevalence of tick caused encephalitis. There's a vaccine for that so we're all vaccinated now.

Otherwise just enjoy your life.

You're the smart one.. Unfortunately I didn't find the tick on time and have been sick with persistent Lyme for over 10 years. Hoping for some kind of solution soon.

And it's relatively easy to get a prescription for since it's a PEP drug for high -er risk sexual activities.

I don't mind there being some selection pressure against biting humans.

and the rabbits and chipmunks and mice and squirrels, as well as that you have to kill basically all deer to the point of about 8 deer per square mile, since one deer can carry 2000-3000 new ticks. which is basically impossible on mainland because new deer just wander over.
