In most cases, fleas are just a nuisance to their hosts, but some people and some animals suffer allergic reactions to flea saliva resulting in rashes. Flea bites in general result in the formation of a slightly-raised swollen itching spot with a single puncture point at the centre. The bites often appear in clusters or lines, and can remain itchy and inflamed for several weeks afterwards. Fleas can also lead to hair loss as a result of frequent scratching and biting by the animal, and can cause anemia in extreme cases. However, fleas can also act as a carrier of disease.
