Tsutsugamushi disease is one of the most febrile illnesses occurring throughout Korea during fall, which is known as a vector-borne disease caused by the bite of mites with rickettsial bacteria Oriental tsutsugamushi. The mites have four-stage life cycles: egg, larva, nymph, and adult. However, Oriental tsutsugamushi can be transmitted only in the larva stage of mites because other stages(nymph and adult) do not feed on hosts. Although there have been many researches on tick-borne diseases, we have never seen any mathematical models on such a mite-borne disease so far. In the present work, we present a model of the disease and show and analyze the basic reproduction ratio R0.
