Scrub typhus malayalam

Background The risk factors for scrub typhus in Vietnam remain unknown. Scrub typhus caused by Orientia tsutsugamushi often presents as an undifferentiated febrile illness and remains under appreciated due to the limited availability of diagnostic tests. This tropical rickettsial illness is increasingly recognized as an important cause of non-malaria acute undifferentiated fever in Asia. This study aimed to investigate behavioural and ecological related risk factors of scrub typhus to prevent this potentially life-threatening disease in Vietnam. Methods We conducted a clinical hospital-based active surveillance study, and a retrospective residence-enrolment date-age-matched case–control study in Khanh Hoa province, Vietnam, from August 2018 to March 2020. Clinical examinations, polymerase chain reaction and enzyme-linked immunosorbent assay IgM tests were applied to define cases and controls. All enrolled participants filled out a questionnaire including demographic socio-economic status, personal behaviors/protective equipment, habitat connections, land use, and possible exposure to the vector. Multivariable conditional logistic regression was used to define the scrub typhus associated risk factors. Results We identified 44 confirmed cases and matched them with 152 controls. Among cases and controls, the largest age group was the 41–50 years old and males accounted for 61.4% and 42.8%, respectively. There were similarities in demographic characteristics between the t...

Background Scrub typhus is a largely ignored tropical disease and a leading cause of undifferentiated febrile illness in the areas of tsutsugamushi triangle caused by Orientia tsutsugamushi. It is frequently diagnosed in South Asian countries, although clear epidemiological information is not available from Nepal. After the 2015 earthquake in Nepal, a sudden upsurge in scrub typhus cases was reported. The objective of this study was to investigate epidemiology of scrub typhus and its causative agents in humans, animals, and chigger mites to understand the ongoing transmission ecology. Methods Scrub typhus cases with confirmed diagnosis throughout the country were included in the analysis. Studies were concentrated in the Chitwan district, the site of a major outbreak in 2016. Additional nation-wide data from 2015 to 2017 available from the government database included to analyse the disease distribution by geographical mapping. Results From 2015 to 2017, 1239 scrub typhus cases were confirmed with the largest outbreak occurring in 2016 with 831 (67.1%) cases. The case fatality rate was 5.7% in 2015 which declined to 1.1% in 2017. A nationwide outbreak of scrub typhus was declared as the cases were detected in 52 out of the 75 districts of Nepal. Seasonal trend was observed with a peak during August and September. In addition to the human cases, the presence of O. tsutsugamushi was also confirmed in animals (rodents) and chigger mites (Leptotrombidium imphalum) from the out...

More than 100 deaths due to fever have health authorities on their toes in What Is Scrub Typhus? It is a disease that is caused as a result of being bitten by tiny insects known as mites. The bacteria causing the disease is known as Orientia tsutsugamushi, the name deriving from the Japanese words ‘tsutsuga’, meaning dangerous, and ‘mushi’, or insect. The disease is also known as bush typhus, tsutsugamushi disease or chigger- borne typhus and was earlier called Rickettsia. A chigger is defined as a “tropical flea, the female of which burrows and lays eggs beneath the host’s skin, causing painful sores". According to the What Are The Symptoms? The US Centres for Disease Control and Prevention (CDC) The A 2017 paper in the How Do Humans Pick Up The Disease? The vector mites most closely associated with scrub typhus are commonly found in forested areas and in areas of “secondary vegetation after clearance of forest areas", NCDC says, adding that the insect is “generally abundant on grasses and herbs where bushes are scarce". Researchers say that infection takes place when humans accidentally pick up an infective larval mite “while walking, sitting, or lying on the infested ground". Locations like forest clearings, riverbanks, and grassy regions are said to “provide optimal conditions for the infected mites to thrive". Where Is It Prevalent? The IJD paper said that more than 1 billion people globally are “at risk for scrub typhus and an estimated one million cases occur annual...

At onset of fever, an eschar often develops at the site of the chigger bite. The typical lesion of scrub typhus begins as a red, indurated lesion about 1 cm in diameter; it eventually vesiculates, ruptures, and becomes covered with a black scab. The capacity of different strains of O. tsutsugamushi to result in an eschar varies, and an eschar is easier to detect in light-skinned people. Regional lymph nodes enlarge. 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. In severe cases, pulse rate increases; blood pressure drops; and delirium, stupor, and muscular twitching develop. Splenomegaly may be present, and interstitial myocarditis is more common than in other ...
