LITERATURE REVIEW
The prevalence of typhoid fever
The global burden of typhoid fever continues to be substantial, with recent estimates indicating millions of cases annually. A comprehensive analysis by Stanaway et al. (2019) estimated that in 2017, there were approximately 14.3 million cases of typhoid and paratyphoid fever worldwide. The study highlighted that the majority of these cases were concentrated in South Asia, Southeast Asia, and sub-Saharan Africa.
In a more recent assessment, Marchello et al. (2020) conducted a systematic review and meta-analysis of typhoid fever incidence in low- and middle-income countries. Their findings corroborated the geographical distribution noted by Stanaway et al., with the highest incidence rates observed in South Asia, followed by sub-Saharan Africa and Southeast Asia. South Asia continues to be a hotspot for typhoid fever. A study by Qamar et al. (2020) in Pakistan found a high prevalence of typhoid fever, with 15.5% of suspected cases testing positive for S. Typhi. The study also noted the emergence of extensively drug-resistant (XDR) strains, complicating treatment efforts. In Bangladesh, a population-based study by Theiss-Nyland et al. (2019) reported an adjusted incidence of 587 cases per 100,000 person-years in children under 16 years old, underscoring the significant burden of the disease in pediatric populations. In Southeast Asia, typhoid fever remains endemic in several countries. A study by Chau et al. (2020) in Vietnam found that while overall incidence has decreased, certain regions still experience high rates of infection. The study reported an incidence of 72.7 cases per 100,000 person-years in Hue province, central Vietnam.
Recent studies have shed light on the prevalence of typhoid fever in various African countries. A multi-country study by Park et al. (2021) across sub-Saharan Africa reported varying incidence rates, with the highest in Burkina Faso (410 cases per 100,000 person-years) and the lowest in Sudan (49 cases per 100,000 person-years). This study highlighted the heterogeneity of typhoid fever prevalence across the continent. In Nigeria, a prospective and case-controlled study was carried out between 2013 and 2016 among 810 febrile patients and 288 healthy individuals. The study collected stool, blood and urine samples and tested for salmonella using the widal test and blood culture. The study found that of the 810 typhoid suspects tested, 114 (14.1%) had positive cultures for the typhoid organisms (Ohanu et al., 2019).
In South Africa, national incidence rates of culture-confirmed typhoid fever have remained constant for 13 years. The national incidence was 0.4 per 100,000 population. Paratyphoid fever remains a rare disease. Antimicrobial susceptibility data suggest resistance to ciprofloxacin and azithromycin is emerging (Keddy et. al., 2018). A systematic review conducted in Ethiopia on the prevalence of Typhoid found that the pooled prevalence of typhoid fever from blood and stool culture diagnosis was 3%. The study also recorded that the stool culture test identified was twofold higher, with a value of 4% compared to a blood culture of 2 percent (Teferi et. al., 2022).
In Ghana, Adu-Sarkodie et al. (2021) found a prevalence of 9.8% among patients presenting with febrile illness at a tertiary hospital. The study emphasized the need for improved diagnostic capabilities to accurately assess the true burden of the disease. Also, a study conducted by Rufai et al. (2023) in the Ga West Municipality of Ghana found that the prevalence of typhoid among patients presenting with febrile illness was 14.6 per cent.

METHODOLOGY
Research Design
This study adopted a quantitative survey research design to investigate the research objectives effectively. A quantitative design involves the systematic empirical investigation of observable phenomena via statistical, mathematical, or computational techniques (Saunders, Lewis, & Thornhill, 2019). In this study, the primary aim was to gather numerical data that would enable an examination of relationships and patterns regarding the variables under investigation. The use of a survey facilitated the collection of quantifiable data from a large group of respondents, which was critical to achieving the study’s objectives (Bell, 2022).
The justification for selecting a quantitative survey research design lies in its ability to provide measurable, generalizable insights (Gray, 2018). Since the goal was to investigate the influence of specific factors on a particular phenomenon, a survey allowed for the efficient collection of a substantial amount of data from a broad population within a limited time frame. Furthermore, the ability to utilize structured questionnaires ensured consistency in the type of data collected, which was essential for drawing valid and reliable conclusions (Creswell & Creswell, 2018). The survey method was also suitable for testing hypotheses by examining the relationships between different variables statistically (Newman & Benz, 2020).
Population of the Study
The target population for this study was set at 1,200 respondents, which constituted a large and diverse group, ensuring that the results would be representative of the broader population under investigation. The population included individuals relevant to the study’s context, such as specific groups or communities influenced by the phenomenon being researched (Saunders, Lewis, & Thornhill, 2019).
The justification for selecting this population was based on the need to obtain a comprehensive understanding of the research problem. A population size of 1,200 ensured that the study could draw meaningful and reliable insights across different subgroups within the community, offering a robust basis for analyzing the data (Charan & Biswas, 2019). Moreover, such a population size allowed for sufficient variability in the responses, which is critical for the accurate assessment of relationships between variables (Tavakol & Dennick, 2021).

SUMMARY, CONCLUSION AND RECOMMENDATIONS
Summary of Findings
The findings from this study on the prevalence of typhoid fever and its associated risk factors in the Goaso District provide a comprehensive overview of the current public health situation concerning this infectious disease. The study aimed to assess the extent of typhoid fever among patients attending hospitals in the district, identify the demographic characteristics of affected individuals, and explore the various risk factors contributing to its prevalence. This summary will encapsulate the major findings, highlighting the significance of the results and their implications for public health policy and intervention strategies.
The study surveyed 120 respondents, achieving a high response rate of 90.8%, which underscores the community’s engagement and willingness to participate in research that addresses critical health issues. Among the 120 questionnaires distributed, 109 were completed and returned, providing a robust dataset for analysis. The demographic breakdown of the respondents revealed a diverse sample, with notable variations in gender and age distribution. The majority of respondents were female (57.8%), while males accounted for 42.2%. This gender distribution reflects broader trends in healthcare seeking behaviors, where women often seek medical attention more frequently than men.
Age-wise, the findings indicated that the majority of respondents (71.6%) fell within the 25-34 years age range, suggesting that young adults are particularly vulnerable to typhoid fever. This demographic insight is critical, as it highlights a target group for health interventions. The presence of a significant number of respondents aged 18-24 years (15.6%) also emphasizes the importance of focusing health education efforts on younger populations. These age groups may benefit from targeted awareness campaigns that educate them about typhoid fever prevention and safe health practices.
Educational attainment among respondents varied, with 59.6% holding a master’s degree, 33% possessing other qualifications, and only 7.3% having a bachelor’s degree. This distribution indicates a relatively well-educated population, which could be advantageous for implementing health education initiatives. However, the high levels of educational attainment did not correlate with a lower prevalence of typhoid fever, suggesting that awareness and knowledge about the disease may not be uniformly high, despite formal education levels. Thus, even well-educated individuals may lack specific knowledge regarding typhoid fever prevention and transmission, underlining the need for focused educational programs.
A critical finding of this study was the high prevalence of typhoid fever among respondents, with 78% reporting a prior diagnosis. This alarming statistic underscores the disease’s endemic nature in the Goaso District and highlights a pressing public health concern. The results correlate with existing literature indicating that typhoid fever remains a significant challenge in many developing countries, particularly in areas with inadequate sanitation and hygiene practices.
The study also examined perceptions of healthcare and sanitation among respondents. A considerable majority (78.9%) believed that the hospital regularly treats a high number of patients diagnosed with typhoid fever, indicating that the community perceives this disease as a significant health issue. Furthermore, 53% of respondents acknowledged that typhoid fever cases are more prevalent in the Goaso District compared to other illnesses, reinforcing the need for targeted health interventions.
Poor sanitation emerged as a significant contributor to the spread of typhoid fever, with 49.5% of respondents agreeing that it plays a critical role in the disease’s prevalence. This finding aligns with global health data emphasizing the importance of environmental health in preventing infectious diseases. The study also identified contaminated drinking water as a significant risk factor, with 42.2% of respondents acknowledging its role in the transmission of typhoid fever. This highlights the urgent need for improved water quality and sanitation infrastructure in the district to mitigate the risk of typhoid fever outbreaks.
Additionally, the findings suggest that inadequate healthcare awareness increases the risk of typhoid fever, with over half of the respondents recognizing this correlation. This indicates a gap in knowledge regarding disease prevention and health-seeking behavior in the community. Furthermore, the frequent consumption of street food was identified as a potential risk factor, with 53.2% of respondents agreeing that it increases the likelihood of contracting typhoid fever. This finding points to the need for regulatory measures and educational initiatives targeting food safety among street food vendors and consumers alike.
Statistical analysis revealed a significant increase in typhoid fever cases over the past year, as noted in the hospital’s records. The one-sample t-test results confirmed that both the prevalence of typhoid fever and the associated risk factors were perceived as significant by the respondents. These findings underscore the necessity for immediate public health interventions to address the increasing trend of typhoid fever cases in the district.
The study’s results provide crucial insights into the intersection of public health, education, and environmental factors influencing the prevalence of typhoid fever in the Goaso District. The alarming rates of diagnosis, coupled with the acknowledgment of key risk factors such as poor sanitation and contaminated water, highlight the urgent need for a coordinated response from health authorities.
In summary, this study highlights the complex interplay of demographic factors, health awareness, and environmental conditions contributing to the prevalence of typhoid fever in the Goaso District. The findings call for urgent public health initiatives aimed at improving sanitation, enhancing healthcare education, and promoting safe food practices within the community. Continuous monitoring and further research are essential to fully understand the evolving dynamics of typhoid fever in this region and to develop effective, evidence-based strategies to combat its prevalence. Addressing these issues will be crucial in improving the overall health outcomes and quality of life for residents in the Goaso District.

Limitations of the Study
This study faced several limitations that could impact the interpretation of the findings. Firstly, the sample size, while sufficient for preliminary analysis, may not fully represent the diverse population of the Goaso District. The study included 120 respondents, of which 109 completed the questionnaire. Such a limited sample size could lead to biases, as certain demographic groups may be underrepresented or overrepresented, affecting the generalizability of the results. Additionally, the study relied on self-reported data, which can introduce recall bias or social desirability bias, as participants may have provided answers they believed were more acceptable rather than their true experiences or beliefs regarding typhoid fever and its associated risk factors.
Another limitation of this study is the cross-sectional design, which captures data at a single point in time. This design restricts the ability to establish causal relationships between the identified risk factors and the prevalence of typhoid fever. Longitudinal studies could provide more insightful data regarding the dynamics of infection rates and risk factors over time. Furthermore, the research did not delve into the specific environmental conditions, such as the quality of sanitation facilities or the prevalence of street food vendors, which could significantly contribute to the understanding of typhoid transmission in the district. Future research should address these limitations by expanding the sample size, employing longitudinal designs, and exploring environmental factors to gain a more comprehensive understanding of typhoid fever in the Goaso District.
Suggestions for Further Studies
To build upon the findings of this study, future research should consider expanding the geographical scope to include neighboring districts or regions with varying socio-economic conditions. This broader approach would provide a more comprehensive understanding of the prevalence and risk factors associated with typhoid fever beyond the Goaso District. Such studies could employ a comparative analysis to identify patterns in infection rates, healthcare access, sanitation standards, and public health awareness. Additionally, including a larger and more diverse sample of participants would enhance the robustness of the findings and allow for more generalized conclusions regarding the prevalence of typhoid fever and its determinants in the larger population.
Moreover, future studies could explore the effectiveness of specific interventions aimed at reducing the incidence of typhoid fever in the community. This could involve assessing the impact of health education campaigns focused on hygiene practices, the provision of clean drinking water, and the regulation of street food vendors. Longitudinal studies would also be beneficial to track changes in prevalence and risk factors over time, allowing researchers to evaluate the long-term effects of interventions on public health outcomes. Investigating the role of environmental and socio-economic factors in greater detail, such as the correlation between sanitation infrastructure and typhoid fever rates, would contribute significantly to the understanding of this disease and inform targeted public health strategies.
