Scrub typhus eschar

Scrub typhus traditionally occurs in people living in Asia, Japan, India, northern Australia and the Pacific Islands. In most cases, a cutaneous eschar develops at the site of inoculation Cheng, V.

Scandinavian Journal of Infectious Diseases 36, no. 10 (2004): 743-751.Mayxay M, Sengvilaipaseuth O, Chanthongthip A, et al. Causes of fever in rural southern Laos. Am J Trop Med Hyg. 2015;93(3):517–520.Scrub typhus is also known as tsutsugamushi disease. The name tsutsugamushi is derived from two Japanese words: tsutsuga, meaning something small and dangerous, and mushi, meaning creature. The infection is called scrub typhus because it generally occurs after exposure to areas with secondary (scrub) vegetation. It has recently been found, however, that the disease can also be prevalent in such areas as sandy beaches, mountain deserts, and equatorial rain forests. Therefore, it has been suggested that the names miteborne typhus, or chigger-borne typhus, are more appropriate. Since the disease is limited to eastern and southeastern Asia, India, northern Australia and the adjacent islands, it is also commonly referred to as tropical typhus.

It has been shown that a single oral dose of chloramphenicol or tetracycline given every 5 days for a total of 35 days, with 5-day nontreatment intervals, actually produces active immunity to scrub typhus. This procedure is recommended under special circum-stances in certain areas where the disease is endemic.

An infection caused by Orientia tsutsugamushi - a small intracellular bacterium related to the family of Rickettsiaceae - the organism is classified on its own and not with other rickettsiaceae as it has differences in genes and cell wall structure.[1] The name scrub typhus was applied after discovery of increased frequency of the disease in scrub or wasteland areas.[2]Infection with scrub typhus is most often self-limiting but can occasionally be severe and even fatal. The incubation period is up to ten days and the commonest features are:

As of early 2004 there are no effective vaccines for scrub typhus. In endemic areas, precautions include wearing protective clothing. Insect repellents containing dibutyl phthalate, benzyl benzoate, diethyl toluamide, and other substances can be applied to the skin and clothing to prevent chigger bites. Clearing of vegetation and chemical treatment of the soil may help to break up the cycle of transmission from chiggers to humans to other chiggers.Kurup A, Issac A, Loh JP, et al.

Typhus: Causes, Symptoms, and Diagnosis Scrub typhus

Scrub typhus is a vector-borne zoonosis endemic in South Asia, Southeast Asia, East Asia, the Pacific Islands, and Northern Australia (the “tsutsugamushi triangle”), with reports of similar infections from Africa, the Middle East, and South America.1 This infection is caused by Orientia tsutsugamushi, which is transmitted to humans by the bite of infected chiggers (larvae) of trombiculid mites.2 The name “tsutsugamushi disease” was given by Hashimoto in 1810.3 The tsutsugamushi triangle is home to more than half the world’s population,4 with 2 billion at risk and 1 million cases of scrub typhus occurring per year.5 Clinical manifestations range from asymptomatic to severe disease. The mortality rate varies and can be as high 50%,6 such that the mortality among 1 million infections in a single year is likely enormous.7 This is because the organism responsible affects the vascular endothelium and mononuclear macrophages. Therefore, all organs, including the lungs, liver, kidneys, and central nervous system, can be affected.8 Misdiagnosis and underdiagnosis is also known to occur due to lack of availability of diagnostic tests and the aspecific nature of symptoms, especially when the characteristic eschar is not present.7,9–11Kim YJ, Yeo SJ, Park SJ, et al.

Scrub typhus is an infectious disease that is transmitted to humans from field mice and rats through the bite of mites that live on the animals. The main symptoms of the disease are fever, a wound at the site of the bite, a spotted rash on the trunk, and swelling of the lymph glands.Watt G, Jongsakul K, Chouriyagune C, Paris R.

Fever rises during the 1st week, often to 40 to 40.5° C. Headache is severe and common, as is conjunctival injection. A macular rash develops on the trunk during the 5th to 8th day of fever, often extending to the arms and legs. It may disappear rapidly or become maculopapular and intensely colored. Cough is present during the 1st week of fever, and pneumonitis may develop during the 2nd week.Suwanabun N, Chouriyagune C, Eamsila C, et al.

Chloramphenicol (Chloromycetin, Fenicol) and tetracycline (Achromycin, Tetracyn) are the drugs of choice. They bring about prompt disappearance of the fever and dramatic clinical improvement. If the antibiotic treatment is discontinued too quickly, especially in patients treated within the first few days of the fever, relapses may occur. In patients treated in the second week of illness, the antibiotics may be stopped one to two days after the fever disappears.

Scrub typhus can mimic other acute febrile illnesses common in the tropics, especially when pathognomonic eschars are absent.10 Therefore, laboratory tests become mandatory for confirmation of the diagnosis.38,75,76 Methods available include direct methods like isolation of the pathogen in cell cultures (HeLa, L929, Vero, and BHK21) and detection of scrub typhus-specific DNA like 56 kDa, 47 kDa, 16S ribosomal RNA, and GroEL gene targets by polymerase chain reaction (PCR). Indirect methods include detection of antibodies to O. tsutsugamushi by immunofluorescence assay (IFA), enzyme-linked immunosorbent assay (ELISA),77 and rapid diagnostic assays.78,79 Tables 4 and 5 give performance characteristics of the available assays for laboratory confirmation of scrub typhus.Primary treatment of scrub typhus is doxycycline 200 mg po once followed by 100 mg bid until the patient improves, has been afebrile for 48 hours, and has received treatment for at least 7 days.Bayesian latent-class modeling has been used to determine diagnostic test performance, as it does not consider any test as perfect.49 In addition, composite criteria involving culture, PCR, and serological positivity like scrub typhus-infection criteria have been used.81 Moreover, a WHO case definition for scrub typhus also is available,93 as is an expert-derived Indian Council of Medical Research case definition.94 Lim et al concluded that combinations of IgM ICT and presence of eschars have good specificity and can be used in resource-poor situations as point-of-care diagnostic tests, whereas performance of a PCR would be very useful in centers with facilities for same.49

Scrub Typhus - Causes, Symptoms, Diagnosis, Treatment

Use tick, mite, and insect repellant. Perform routine examinations for ticks, and wear protective clothing if you’re traveling near an area where there have been typhus outbreaks.In severe cases, pulse rate increases; BP drops; and delirium, stupor, and muscular twitching develop. Splenomegaly may be present, and interstitial myocarditis is more common than in other rickettsial diseases. In untreated patients, high fever may persist ≥ 2 week, then falls gradually over several days. With therapy, defervescence usually begins within 36 hours. Recovery is prompt and uneventful.Varghese GM, Janardhanan J, Mahajan SK, et al.

Parameters that show very significant P-values (0.01) by multivariate logistic regression analysis have been included in the tables. In a meta-analysis of 89 studies (19,644 patients with scrub typhus), fatal outcome was reported in 2,488 patients, with an overall mortality of 12.7%. Though increasing age was associated with fatality, presence or absence of eschars did not affect the outcome.65Kim DM, Yun NR, Neupane GP, et al.

Am J Trop Med Hyg. 2007;76(5):801–805.R. tsutsugamushi lives primarily in mites that belong to the species Leptotrombidium (Trombicula) akamushi and Leptotrombidium deliense. In Japan, some cases of scrub typhus have been reportedly transmitted by mites of the species Leptotrombidium scutellare and Leptotrombidium pallidum. The mites have four-stage life cycles: egg, larva, nymph, and adult. The larva is the only stage that can transmit the disease to humans and other vertebrates.

J Microbiol Immunol Infect. 2015;48(1):121–122.Abbreviations: IFA, immunofluorescence assay; ELISA, enzyme-linked immunosorbent assay; ICT, immunochromatographic test.Diagnostic procedures involving the actual isolation of rickettsiae from the blood or other body tissues are usually expensive, time-consuming, and hazardous to laboratory workers. As a result, several types of tests known as serological (immunological) tests are used widely to confirm the clinical diagnosis in the laboratory.The seasonal occurrence of scrub typhus varies with the climate in different countries. It occurs more frequently during the rainy season. Certain areas such as forest clearings, riverbanks, and grassy regions provide optimal conditions for the infected mites to thrive. These small geographic regions are high-risk areas for humans and have been called scrub-typhus islands.Land MV, Ching WM, Dasch GA, et al.

During World War II, a vaccine was created to prevent epidemic typhus. However, the shrinking number of cases has stopped the manufacture of the vaccine. The easiest way to prevent typhus is by avoiding the pests that spread it.In addition to temperature, secondary vegetation and rainfall also increase the incidence of scrub typhus.33 Occupational risk is higher in farmers (aged 50–69 years), females,6 and those working in vegetable fields, harvesting in autumn,34 and rural highlands.35 In a study by Kweon et al, outdoor activities like resting on a grass field without a mat, working in short sleeves and bare hands, and defecating and/or urinating outdoors while squatting increased risk for scrub typhus.12 In a case-control study from South Korea, individuals engaged in fruit farming, gathering chestnuts, and taking breaks in areas adjacent to agricultural operations had an increased risk of contracting scrub typhus compared to controls. The authors opined that providing a health-education program would lower the risk in these individuals and similar groups.36 Land use is another determinant, as scrub-typhus incidence increases when forest lands are converted to fields, palm oil, and rubber plantations,2and also when urbanization occurs.36Jim WT, Chiu NC, Chan WT, et al.

Scrub typhus, also known as bush typhus, is a disease caused by a bacteria called Orientia tsutsugamushi. Signs and symptoms may include: Figure 1. Eschar at site of chigger bite Kvalsterburen fläcktyfus (Scrub typhus) orsakas av Orientia tsutsugamushi, förekommer mest i Svårare fall med vaskulitbild förekommer men är sällsynt. I ungefär hälften av fallen ses eschar

O. tsutsugamushi is transmitted by trombiculid mite larvae (chiggers), which feed on forest and rural rodents, including rats, voles, and field mice. Human infection also follows a chigger bite. The mites are both the vector and the natural reservoir for O. tsutsugamushi.Park JH, Kim SJ, Youn SK, Park K, Gwack J.

Manifestations of scrub typhus are similar to those of Rocky Mountain spotted fever and epidemic typhus. However, scrub typhus occurs in different geographic areas (Asia-Pacific area bounded by Japan, Korea, China, India, and northern Australia), and frequently, an eschar develops with satellite adenopathy.Peter JV, Sudarsan TD, Prakash JA, Varghese GM. Severe scrub typhus infection: clinical features, diagnostic challenges and management. World J Crit Care Med. 2015;4(3):244–250.Serological tests— Tests of immune function that are performed using the clear yellow liquid part of blood.Intracellular parasite— An organism which can only feed and live within the cell of a different animal.Scrub typhus is an important cause of febrile illness in the Asia-Pacific region. The main management challenge is institution of specific therapy in a timely and an effective manner, as stated elsewhere in this review. For this, rapid and accurate diagnosis becomes necessary, especially in the absence of eschars. In resource-poor endemic settings, clinical prediction rules have been defined and found useful. In addition, a battery of tests is needed for increasing diagnostic yield and sorting out the issue of coinfections. Finally, appropriate treatment should be initiated, keeping in mind the risk and benefits afforded by such treatment.

Scrub typhus is a bacterial infection caused by Orientia tsutsugamushi. The disease is prevalent in a very large geographical area and usually presents with undifferentia.
