Are fleas dangerous to humans?

Answer

Fleas are not generally dangerous to humans, although they can be troublesome. Most flea bites require minimal treatment with a mild cortisone cream or an antibiotic ointment. Infestations are a concern, however, and can cause prolonged discomfort, respiratory trouble and other symptoms.

In the absence of an allergy, a single flea bite will probably not cause lasting distress. Flea bites usually appear as small red dots, bumps or bubbles and are often found around the ankle area. Usually, the fleas responsible for human bites come from dogs, cats and other small animals. Multiple flea bites may require treatment with an antihistamine or corticosteroid cream. If symptoms of an allergic reaction, such as extensive redness, severe itching or shortness of breath occur, medical attention should be sought as soon as possible.
