Can flea bites be dangerous to humans?

I recently moved in with a friend on the other side of the country and have been here for two days. I just found out her cat has fleas (it's been living outside and I've never even seen it). About half an hour ago I noticed some red bumps on my foot. I checked the other foot for bumps too and found a flea. I have about seven bites on my feet alone and have no idea if it's bitten me elsewhere. I told my friend and she gave me some aloe vera and changed my bed sheet. Can these bites cause a real threat? I am allergic to mosquito and insect bites and I have never been bitten by a flea before.

They itch - and in the middle ages, it's fleas that spread plague. More of a nasty nuisance - you shouldn't suffer any ill health effects. The cat is probably miserable!

Ya'll need to get rid of them and get the cat some Frontline - you'll need to spray carpets and anywhere they are hiding, they breed fast - so don't wait to start getting rid of them.

I think that fleas can spread tape worm and typhus, so if you're worried about that sort of thing you might want to talk to your doctor. Report It

Potentially - remember that the Bubonic Plague spread throughout the world via flea bites.

Just be really careful. Don't let her cat in your room. I know if you swallow a flea it can give you worms.

Keep an eye on the bumps to make sure they don't get too big, red, etc.

No i dont think they can harm you they only suck your blood and are annoying i get flea bites all the time because i have 5 cats in my house but i dont get bitten all the time when i do i get really annoyed and pissed off the stupid cat sleeps on my bed i have to kick it out everytime.
