Yes, that's one more reason it's important to prevent fleas in the first place, as well as take immediate action against flea infestations. Fleas can transmit a number of diseases to your pets and their human families. That's not saying every flea bite will contain disease, but it's certainly not worth the risk!

For the long winded, big worded details, the CDC (Centers for Disease Control and Prevention) has an article on flea borne diseases.
