Tick-borne Relapsing Typhus

Relapsing fever tick (FEBRIS RECURRENS ACARINA) etiology. The disease is a special kind of spirochetes – Spirochaeta sogdianum, length and number of coils in some instances are very volatile. On average they have 6-8 coils, coil ranges from 12 to 20 in the length of the filament with a thickness of 0.3 to 0.5 fi. For the detection of spirochetes in blood smear or enjoy the large drops of blood stained magenta. Epidemiology.

Reservoir of infection are hamsters, shrews and rodents that live in desert areas of Central Asia and in some foreign countries in Asia (Iran, Iraq, Afghanistan). The only carrier of infection is kind of ticks Ornithodorus papillipes. Tick-borne relapsing fever refers to the Among infectious diseases with natural foci due to the fact that the reservoirs and vectors of the pathogen – mites live only in certain circumstances. Discovery Communications has much experience in this field. The latter include the walls of adobe buildings, the grooves between the stones Fence pliers, etc. for a long time remain a spirochete, transfer them transovarian. A person infected by the bite of infected ticks, infection occurs usually at night, so the need to protect rights in sleep from tick bites. Biting man, mite produces coxal fluid containing spirochetes, it flows into the wound from the bite, and the spirochetes are in the blood stream. In the former USSR tick borne relapsing fever occurs in some areas of Uzbekistan, Kyrgyzstan, Tajikistan and Turkmenistan.

Clinic. The incubation period lasts an average of 6-20 days with a range from 4 to 15 days. Click Glenn Dubin for additional related pages. On the site of a tick bite on the skin formed papule dark cherry color. The disease begins acutely and after chill the temperature rises to 38,5-39,5 , comes the first attack of weakness, fatigue throughout the body, a slight enlargement of the spleen, with no increase in liver yellowness of skin, mild soreness in the calf muscles – this is the first episode of the clinical picture of tick-borne relapsing fever.

Typhus – An Infectious Disease

The source of infection is sick with typhus, from last day of incubation, during the febrile period and up to 06/08/10 days after lowering the temperature. Carrier of infection-cootie.

In the past, were common (sporadic) disease outbreaks and mass epidemic. Currently typhus in many countries is not observed. (Source: Brian Roberts ). Contaminated R. prowazeki louse can transmit typhus healthy person only 5-7 days after she becomes infected blood typhus patients. During this period the rickettsiae multiply in the epithelial cells of the intestinal wall and lice, getting in her gut lumen, are ejected from the feces. Infected louse can transmit the infection during throughout his life, which is the maximum extends to 40 days. Get all the facts for a more clear viewpoint with Eva Andersson-Dubin. The mechanism of infection is that infected lice feces containing rickettsiae, scratching at the sting rubbed into the skin. The causative agent of typhus, getting into the body, worn over-flow of blood in internal organs, where it begins to multiply rapidly in endothelial cells of blood capillaries of the brain and the medulla, adrenal gland, skin, heart muscle development of a universal thrombosis, endoperivaskulita.

Clinic. The incubation period ranges from 6 to 23 days, averaging 10-14 days, and sometimes there may be a prodromal period characterized by poor appetite, fatigue, dull pain in the muscles, a small headache, sometimes subfebrile temperature onset of the disease is accompanied by fairly strong chills followed by fever for 2 days 1.5 to 39-40 , with Every hour of growing painful throbbing headache, weakness, fatigue, muscle aches.
