Queensland tick typhus

Queensland tick typhus

**Tick-borne typhus** (T. q. australicus, t. juxta or typhus quinchlyenais) is an acute intestinal infectious disease caused by a specific ricketts, the causative agent of Australian tick-borne rickettsiosis. It is transmitted through the bite of an infected (free or convicted) mosquito. The source of the pathogen is lice, mosquitoes and people with an uncomplicated form of the disease, who release the pathogen into the external environment with urine, blood (up to 2 weeks), saliva, and feces. The duration of the incubation period is from 3 to 8 days, most often 7–10 (sometimes up to 14) days. With normal kidney function, tick-borne typhus lasts 2-3 weeks, and during the period of impaired renal function it is replaced by a recovery period lasting about 6 weeks. As complications of tick-borne typhus, nephroso-nephritis usually develops, sometimes leading to death, then otitis media, pneumonia and myocarditis, which are recorded quite rarely in children under one year of age, but are observed in old people and in severe forms of the disease in adolescents, as well as in
