Scrub typhus, caused by the bacterium Orientia tsutsugamushi and transmitted through the bite of infected larval mites, is a potentially life-threatening vector-borne disease prevalent in various parts of Asia, including India. As a picturesque region known for its natural beauty and outdoor attractions, Shimla, Himachal Pradesh, draws tourists and outdoor enthusiasts from far and wide. However, this idyllic landscape also harbors the risk of scrub typhus infection, making it crucial to assess the awareness and knowledge levels regarding this disease among the local and visiting population [1-3].

Scrub typhus often presents with non-specific symptoms, including fever, headache, and muscle pain, making it challenging to diagnose without specific medical tests. Delayed diagnosis and treatment can lead to severe complications and even fatalities. Therefore, it is imperative to ensure that individuals engaging in outdoor activities in Shimla are well-informed about scrub typhus, its transmission, symptoms, and preventive measures [4,5].

This study aims to bridge the gap in understanding scrub typhus by assessing the awareness and knowledge levels among the general public in Shimla. By doing so, we intend to contribute to the development of targeted public health campaigns and educational initiatives that will promote safer outdoor activities, early detection, and effective prevention of scrub typhus in this scenic region.

The questionnaire is designed to evaluate participants' knowledge on scrub typhus, its mode of transmission, symptoms, and preventive measures, with each correct response receiving one mark and incorrect answers receiving zero marks. Based on their scores, participants' knowledge levels are categorized into four groups: very good (>80%), good (60-79%), fair (41-59%), and poor (<40%). This scoring system allows for a clear understanding of the overall awareness levels among respondents.

Data Collection and Analysis

Data collection is conducted under the supervision of experienced supervisors, and the Google Form questionnaire is disseminated through various online platforms, such as email, WhatsApp groups, Facebook, Instagram, and LinkedIn, to reach both rural and urban areas of Shimla. Collected data is then meticulously entered into a Microsoft Excel spreadsheet and thoroughly checked for accuracy and completeness. Epi Info V7 software is employed for data analysis, and appropriate statistical tests, such as frequencies and percentages, are used to present the findings in a clear and concise manner.

Ethical Considerations

Throughout the study, utmost care is taken to adhere to ethical guidelines to ensure the privacy and confidentiality of participants. Informed consent is obtained from all respondents before their inclusion in the study, and their personal information is kept confidential. The research team ensures that all data is anonymized, safeguarding the participants' identities at all times
