Pulicosis is a skin condition caused by several species of fleas, including the cat flea (Ctenocephalides felis) and dog flea (Ctenocephalides canis). This condition can range from mild irritation to severe irritation. In some cases, 48 to 72 hours after being bitten, a more severe rash-like irritation may begin to spread across the body.
Cat fleas originated in Africa [4] but can now be found globally. [5] As humans began domesticating cats, the prevalence of the cat flea increased and it spread throughout the world.

It is caused by the bacterium Rickettsia typhi, and is transmitted by the fleas that infest rats. While rat fleas are the most common vectors, cat fleas and mouse fleas are less common modes of transmission. These fleas are not affected by the infection. Human infection occurs because of flea-fecal contamination of the bites on human skin.
