Fleas jump from host to host, so a flea can jump from one cat to another if bitten, but the bite itself will not cause the fleas.
I would recommend taking your cat to the vet.
Bartonella henselae can infect people who are scratched or (more rarely) bitten or licked by a cat.
The cat with fleas is a host
While cat fleas (Ctenocephalides felis) and dog fleas (Ctenocephalides cannis) are two different species, most of the fleas found on dogs are actually cat fleas.
Fleas on a cat are probably either dog fleas or cat fleas (these are two different species, but despite the name, either can survive on either a dog or cat ... or for that matter on other mammals). Both of them can and will bite humans.
Your cat might itch because it has fleas or merely that it has been bitten by a mosquito, gnat, etc.
Rabies is transmitted through the salvia. If a cat has rabies, he can infect you with it. If a person is bitten or scratched by a cat with rabies, they have the possibility of getting rabies. An animal with rabies can show several symptoms. It can be disoriented, dumb looking, vicious, tired, foaming at the mouth, and/or unable to swallow. The only way to check for rabies is to send the head of the animal off for brain biopsy. For humans there is no test. If you are bitten or scratched by a rabies animal, go get rabies shots immediately.
No, fleas will live in your home and bite people instead. Your home will need to be treated for fleas if a fleas are seen!

Only through deep bite or scratch wounds where the saliva of the cat who is infected enters the other cat's bloodstream, or from pregnant cats to their offspring.
