Humans affected by flea bites can suffer from an allergic reaction to the flea saliva, known as flea allergy dermatitis. Dog and cats are commonly identified as flea hosts, but rodents, birds and small furry animals can also carry fleas. If you believe your flea bites are from animals other than dogs or cats, your reaction may be more than just allergic, and you should see a doctor to eliminate the possibility of certain flea-transmitted diseases especially prevalent in developing countries 4.
While allergic reactions vary by individual, itchiness is one of the main symptoms of flea allergy dermatitis. All flea bites cause some itching, but those who suffer from flea allergy dermatitis experience a whole-body itching sensation. Children with allergic reactions may scratch until they develop open sores. Prevent secondary infections by applying an anti-histamine and anti-bacterial cream to the skin regularly before covering the bites with bandages. To solve the problem, either have a professional exterminate the fleas or do it yourself using flea bombs, and apply spot treatment to your dog or cat immediately.
