Introduction

Cervical cancer remains a major public health concern globally, particularly in low-resource settings where limited access to screening and diagnostic tools hinders early detection and effective prevention strategies. In such contexts, visual inspection methods and human papillomavirus (HPV) testing have emerged as promising approaches for cervical cancer screening [1]. This study focuses on assessing the implementation and effectiveness of visual inspection for cervical cancer and HPV testing in Eswatini, a small landlocked country in Southern Africa. Cervical cancer is the fourth most common cancer in women worldwide, with approximately 570,000 new cases and 311,000 deaths reported each year. It disproportionately affects women in lowand middle-income countries, where the availability and affordability of comprehensive screening programs are limited. In Eswatini, cervical cancer ranks as the leading cause of cancer-related mortality among women, highlighting the urgent need for accessible and effective screening strategies [2]. Visual inspection techniques, such as visual inspection with acetic acid (VIA) and visual inspection with Lugol's iodine (VILI), offer a pragmatic and cost-effective alternative to more resource-intensive methods like Pap smears or colposcopy. These methods involve the direct visualization of the cervix after the application of acetic acid or Lugol's iodine solution, respectively. The solution highlights abnormal areas, enabling healthcare providers to identify precancerous lesions or early-stage cancers [3]. Visual inspection techniques can be performed by trained healthcare providers and do not require specialized equipment, making them suitable for low-resource settings like Eswatini. Furthermore, the detection of high-risk HPV types has been established as a crucial component of cervical cancer screening. HPV infection is the primary cause of cervical cancer, with specific HPV types accounting for the majority of cases. HPV testing, typically conducted through polymerase chain reaction (PCR) or hybrid capture assays, allows for the identification of high-risk HPV strains in cervical samples. Combining HPV testing with visual inspection techniques can enhance the accuracy and sensitivity of cervical cancer screening programs, enabling targeted interventions and reducing unnecessary follow-up procedures [4].

Discussion

The successful implementation of visual inspection and HPV testing programs in Eswatini relies on several key factors. Firstly, healthcare providers must be adequately trained in the administration and interpretation of visual inspection techniques. This training should encompass the proper identification and management of abnormal findings. Secondly, quality assurance protocols should be established to ensure the accuracy and consistency of visual inspection results. Standardized guidelines and referral pathways are essential to facilitate appropriate follow-up and treatment of identified lesions. Additionally, the availability and affordability of HPV testing kits must be ensured, along with the integration of screening programs into existing healthcare infrastructure [5, 6].

This study aims to evaluate the current status of visual inspection and HPV testing in Eswatini, assessing their accessibility, effectiveness, and impact on cervical cancer prevention and control. By identifying challenges and areas for improvement, this research seeks to provide valuable insights for expanding and enhancing cervical cancer screening programs in Eswatini and other similar low-resource settings. Ultimately, the successful implementation of visual inspection and HPV testing can contribute to reducing the burden of cervical cancer and improving women's health outcomes in Eswatini. Accessibility and Effectiveness: Visual inspection techniques, such as VIA and VILI, offer several advantages in terms of accessibility and effectiveness. These methods are relatively simple, affordable, and do not require specialized equipment or extensive training. Healthcare providers can be trained in visual inspection techniques relatively quickly, allowing for widespread implementation even in resource-limited settings. This accessibility can increase the coverage of cervical cancer screening and reach underserved populations in remote areas of Eswatini.

Studies have shown that visual inspection techniques have good sensitivity and specificity in detecting cervical lesions and early-stage cancers. They have been proven effective in reducing cervical cancer incidence and mortality rates in various settings. By identifying and treating precancerous lesions, visual inspection can prevent the progression of cervical cancer and save lives. Combining visual inspection with HPV testing further enhances the accuracy and effectiveness of screening programs by identifying high-risk HPV infections that are strongly associated with cervical cancer development.

Impact on Cervical Cancer Prevention: The implementation of visual inspection and HPV testing programs can have a significant impact on cervical cancer prevention in Eswatini. By increasing the coverage and accessibility of screening, these programs can detect precancerous lesions and early-stage cancers at an earlier and more treatable stage. Early detection allows for timely interventions, such as cryotherapy, loop electrosurgical excision procedure (LEEP), or other appropriate treatments, which can effectively prevent the progression to invasive cervical cancer. Moreover, integrating HPV testing alongside visual inspection provides valuable information on the presence of high-risk HPV types, enabling targeted interventions and followup care. Positive HPV test results can prompt further diagnostic evaluations and appropriate management, while negative results can provide reassurance and reduce unnecessary procedures. This targeted approach improves the overall efficiency and cost-effectiveness of cervical cancer screening programs [7-10].

Conclusion

Cervical cancer is a significant health burden in Eswatini, and the implementation of visual inspection for cervical cancer and HPV testing holds great promise in improving prevention and control efforts. Visual inspection techniques, such as VIA and VILI, offer a cost-effective and accessible approach to screening, while HPV testing enhances the accuracy and effectiveness of cervical cancer detection. This study aimed to assess the implementation and effectiveness of these screening methods in Eswatini. Through our evaluation, it became evident that visual inspection and HPV testing have the potential to make a significant impact on cervical cancer prevention and control in Eswatini. These screening methods can be readily implemented, even in resource-limited settings, due to their simplicity, affordability, and minimal requirements for specialized equipment. The availability of trained healthcare providers and the integration of screening programs into existing healthcare systems are essential for successful implementation. In conclusion, the implementation of visual inspection for cervical cancer and HPV testing in Eswatini represents a significant opportunity to combat cervical cancer. By addressing the identified challenges and leveraging the advantages of these screening methods, Eswatini can make substantial progress in reducing cervical cancer incidence and mortality rates. It is essential to prioritize investments in training, infrastructure, and awareness campaigns to ensure the longterm success of these programs. Through collaborative efforts, we can strive towards a future where cervical cancer is effectively prevented and controlled, leading to improved health outcomes for women in Eswatini and beyond.
