Tuberculosis (TB) has been a persistent global health challenge for centuries, affecting millions of lives and posing a considerable burden on healthcare systems worldwide. Despite significant advancements in medical science and treatment options, this ancient disease continues to afflict individuals and communities, demanding collective efforts for its control and eventual eradication. In the picturesque hill station of Shimla, nestled in the Himalayan foothills of Himachal Pradesh, India, TB represents an ongoing public health concern that requires the attention and active engagement of the community [1-3].

TB is a bacterial infection primarily caused by Mycobacterium tuberculosis, affecting various parts of the body, most commonly the lungs. It is transmitted from person to person through the air when an infected individual coughs or sneezes, making it highly contagious. TB can manifest in different forms, including latent TB infection, where the bacteria remain dormant, and active TB disease, which can lead to severe illness and, in some cases, death. While TB is preventable and curable, timely diagnosis and appropriate treatment are critical in its management [4-6].

In the backdrop of Shimla's scenic landscapes and serene surroundings lies a critical challenge—raising awareness and knowledge about TB within the local community. Effective TB control and prevention necessitate not only a strong healthcare system but also active participation and understanding among the general public. This study endeavors to assess the level of awareness and knowledge regarding TB among the residents of Shimla, recognizing the vital role that community resilience plays in combating this infectious disease.

The significance of this assessment cannot be understated, as TB remains one of the top infectious killers    worldwide,    claiming    over   4,000   lives   daily, according to the World Health Organization (WHO) (WHO, 2021). India has a notably high TB burden, contributing significantly to the global TB crisis. In the pursuit of ending the TB epidemic by 2030, the WHO has outlined strategies that include raising awareness, early detection, and prompt treatment (WHO, 2020). This study aligns with these global efforts by seeking to enhance understanding and awareness of TB within the Shimla community [5-7].  

In the absence of adequate awareness, TB may go undiagnosed or untreated, resulting in prolonged illness, complications, and increased transmission rates. By evaluating the knowledge levels and perceptions of TB among Shimla's residents, this study aims to identify knowledge gaps and areas requiring intervention. These findings will serve as a foundation for designing community-based educational programs and awareness campaigns aimed at preventing TB, fostering early detection, and promoting treatment adherence.

Furthermore, it is crucial to recognize the stigma often associated with TB, which can deter individuals from seeking care and hinder the community's response to the disease. Addressing misconceptions, fostering empathy, and providing accurate information are essential components of this study's objectives. Through a collaborative effort, Shimla can bolster its community resilience, reduce the impact of TB, and contribute to the global endeavor to eliminate this ancient scourge.

The research is conducted in Shimla, renowned for its diverse population and urban lifestyle. The study duration spans from April 2023 to July 2023, during which data collection and analysis are performed.

Study Population and Sample Size

The study's target population comprises all adults above 18 years of age who have resided in Shimla for a minimum of 12 months. A sample size of 400 adults is determined, considering a 50% estimated knowledge level about Tuberculosis , a 5% absolute error, a 95% confidence level, and a 5% non-response rate. This sample size ensures adequate representation and generalizability of findings to the larger population.

Data Collection Tool

To gather information on Tuberculosis awareness, a well-structured and validated Google Form questionnaire is developed. The questionnaire consists of two sections: the first section captures socio-demographic data, including age, gender, marital status, religion, employment, and education, while the second section comprises 20 carefully crafted questions related to knowledge about Tuberculosis.

Description of the Questionnaire

The questionnaire is designed to evaluate participants' knowledge on Tuberculosis, 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.

The goal of the current study was to assess the knowledge regarding Tuberculosis among general public of Shimla through a non-experimental descriptive survey. A total of 400 respondents including 267 (66.75%) were from urban area and 133(33.25%) were from rural area were participated in the study (Table 1).
