Scrub Typhus is one of the most severe and life-threatening conditions that individuals are experiencing worldwide and has become a general medical problem. NIH states that Scrub Typhus is projected to affect 1 billion people globally covering more than 8 million kilometers from rural areas of South and Southeast Asia, the Western Pacific from Korea to Australia as well as Japan, India, and Pakistan. Approximately, 1 million cases of Scrub Typhus occur annually.
However, an NIH report states that, according to prospective fever studies conducted in Asia, Scrub Typhus is a considerable contributor to non-malarial febrile diseases. The prevalence rate of widespread Orientia tsutsugamushi infection ranges from 9.3% to 27.9% and the incidence is increasing daily, specifically in Asia.
A systematic analysis of the Scrub Typhus burden in India's "Tsutsugamushi Triangle" indicated that Scrub Typhus accounts for at least 25.3% of people with acute undifferentiated febrile illness (AUFI). Scrub Typhus continues to be an overlooked disease in terms of research and the development of health care policy while being one of the most prevalent infections of the cause of such frequently observed diseases.
Moreover, in 2022, research looked at the clustering of Scrub Typhus cases among children in three adjacent administrative areas in South India over the course of five years. It discovered that temperature, humidity, and rainfall all played a significant effect on the occurrence of Scrub Typhus.
Furthermore, the importance of climate in increasing the rate of extremely contagious disease has been highlighted by a rise in instances of Scrub Typhus in Odisha. According to government sources, at least six cases of disease-related deaths have been documented from the western regions of the state since September 1, 2023 — five in the Bargarh district and one in the Sundargarh district.
In addition to that it has also been reported in areas like Himachal Pradesh, where sources claim ~295 people have been affected and at least nine people have died as a result of the Scrub Typhus disease in the Shimla district.
At the Veer Surendra Sai Institute of Medical Sciences and Research (VIMSAR), Bural there were 30 positive cases of Scrub Typhus in September 2023 reported by the Times of India News. The condition of all of the patients is now stable and they have been cured with the best medical treatment.
The rickettsial bacteria Orientia tsutsugamushi causes the infectious disease Scrub Typhus. Antigenic variation is abundant in the causative organism. The bite of a Trombiculid mite larva transmits it to humans. The disease can affect persons of all ages as well as travelers from all over the world who have visited endemic areas.
After an incubation period of 6-21 days, clinical symptoms such as fever, headache, myalgia, and gastrointestinal symptoms commonly appear. Scrub Typhus is distinguished by the development of an eschar, which generally begins as a primary papular lesion and eventually crusts to create a black ulcer with core necrosis. Eschar occurs in 10% to 90% of cases of acute Scrub Typhus; however, these cases are sometimes ignored as per NIH.
The market for infections with Scrub Typhus is projected to be influenced by factors comprising the increasing incidence of Scrub Typhus nationwide. The sector is expanding significantly due to the increased frequency of medical conditions worldwide and the difficulties in determining the underlying causes of disease development.
As a result of the Scrub Typhus outbreak, there are higher hospitalizations and thus, increased demand for therapeutic products for symptomatic treatment has become an important factor for market growth. In addition to the above, the government's initiatives from different regions to halt the spread of the bacteria Orientia tsutsugamushi and stop the outbreak of a new pandemic are also assisting the industry's development.
DiseaseLandscape Insights facilitates making informed choices in the field of medical technology, treatments, and diagnostics where different technologies and remarkable advancements will transform the landscape leading to higher growth.
For proper patient care, early detection of Scrub Typhus infection is essential because it guides treatment decisions and assists in minimizing complications. The following serological diagnostic tests are performed to detect the scrub typhus infection.
The Indirect Immunofluorescent Antibody (IFA) is considered the gold standard test for diagnosis of scrub typhus disease. The test works on a concept of detecting antibodies in the serum of the infected patient using fluorescence-labeled anti-human immunoglobulin.
This approach has a number of drawbacks since it needs further testing to show the distinction between a fourfold rise in antibody titers in the acute phase of serum samples and later in the subsequent phase. As a result, it is a historical diagnosis and does not influence how to handle an acute illness.
After changing the IFA techniques, the IIP test was introduced to address the previous flaw. Since this technique employs peroxidase-labeled antibodies rather than fluorescein, a diagnosis is established without the need for a fluorescent microscope. Results from IIP techniques have been comparable to those from IFA. The different strains, like in IFA, have an impact on this test's sensitivity. A fluorescence microscope is no longer necessary, although technical knowledge is still required.
As IFA resources are not frequently available in common laboratories, it is now the method of choice for serological diagnosis in acute scrub typhus infection. For its detection, recombinant p56-kDa type-specific antigens of O. tsutsugamushi strains are combined with IgM antibodies made against the strains of Karp, Kato, Gilliam, and TA716 in acute infections. A recent infection with O. tsutsugamushi is detected with the sensitive test IgM ELISA.
PCR has a significant advantage in that it identifies infections sooner since it detects diseases before antibodies are detected by serological techniques. Eschar tissue cultures, however, have shown beneficial findings even up to 7 days after the administration of antibiotics. The expense of PCR hinders its use in routine diagnosis in endemic regions, despite the fact that it is very sensitive and specific in identifying very low quantities of copies.
Bacterial Culture tests are performed by collecting the sample from blood or skin biopsy. The sample is cultured on specific media at biosafety level 3 and requires technical expertise to conduct the test. However, because of these time-consuming procedures, culture is rarely effective as a diagnostic tool in a clinical environment. Therefore, the work is still only being done for study at reference labs.
Among all the tests listed above, the Indirect Immunofluorescent Antibody is the standard test used to diagnose scrub typhus. Because it is a more specific and sensitive test compared to others. However, the Indirect Immunofluorescent Antibody test is generally not available in developing countries where scrub typhus is widely present. The key players have opportunities to manufacture Indirect Immunofluorescent Antibody test kits.
The market for diagnosis of Scrub Typhus is evolving and expanding. Market players should use technologies to develop novel diagnostic kits and instruments. The development of rapid, low-cost kits and technologies to improve patient health is also essential in the diagnostic field of scrub typhus.

Scrub Typhus is spread widely in the world. So, there is a need to manage the Scrub Typhus with proper medications. As the bacteria are present everywhere individuals get affected easily. The treatment options available to manage the scrub typhus are antibiotics.
For scrub typhus, Tetracycline, Azithromycin, Doxycycline, and Rifampicin are efficient antibiotics. Several trials, notably on Doxycycline and Azithromycin, utilized diverse dosage regimens that included a loading dose of both medicines followed by maintenance doses with an average length of therapy of 7 days for Doxycycline and 3 days for Azithromycin. Tetracycline and Rifampicin are also effective scrub typhus antimicrobials.
However, after 3 days, the bacterial count was decreased by doxycycline, rifampin, and azithromycin individually to 6.2%, 8.8%, and 9.6% of the baseline bacterial count, which provide the excellent effectiveness of antibiotics now used in clinical practice. Studies on antibiotic combinations for the treatment of scrub typhus are few. In cell culture, combinations of doxycycline and azithromycin, doxycycline and rifampin, and rifampin and azithromycin had antibacterial properties comparable to those of the individual drugs.
