Dog fleas can be harmful to humans in that they may carry bacteria and viruses which can be spread from animals to people. In addition, dog fleas will bite people in order to obtain a blood meal if the opportunity arises.
Other than the discomfort of being bitten, most people will not suffer any further health consequences from a flea bite. But if a person’s immune system is weakened or compromised, he may contract a virus from a flea bite, or the skin around the bite itself might become infected.
It is relatively easy nowadays to control a flea infestation in the home by utilizing a topical flea treatment such as Advantage.
If you do get flea bites, simply make sure that the bite is clean so as not to become infected. You may also apply calamine lotion to reduce the itching and inflammation.
