Introduction

Leprosy, also known as Hansen’s disease, is a chronic infectious disease primarily affecting the skin, peripheral nerves, upper respiratory tract, and eyes. Although the global incidence of leprosy has significantly decreased in recent decades, it remains a public health concern in many developing countries. Leprosy is particularly prevalent in areas with limited healthcare access, poor sanitation, and low socioeconomic conditions. Managing leprosy in these settings poses unique challenges, including timely diagnosis, patient adherence to treatment, and managing complications such as disabilities and stigmatization. This literature search aims to explore various strategies for managing leprosy in developing countries, focusing on early detection, treatment approaches, rehabilitation, and the role of community-based interventions.

Key Areas of Management

  1. Early Detection and DiagnosisEarly diagnosis is crucial in preventing the long-term complications of leprosy, including nerve damage and permanent disability. However, diagnosing leprosy in developing countries can be challenging due to the lack of awareness, limited diagnostic facilities, and the often subtle initial symptoms of the disease.
  • Clinical Diagnosis and Screening Programs: Studies emphasize the importance of community-based screening programs, particularly in high-burden areas. Regular screening of high-risk populations—such as people living in poverty, migrants, and individuals in remote areas—can facilitate early detection. Research has shown that integrating leprosy screening into routine health services (e.g., immunization programs) can increase case finding (Ramachandran et al., 2020).
  • Diagnostic Tools: Advances in molecular diagnostics, such as PCR (Polymerase Chain Reaction) testing for Mycobacterium leprae, hold promise for improving early detection, though these tools are not widely available in resource-poor settings (Periyasamy et al., 2019). Additionally, newer biomarkers and serological tests may contribute to more accurate and rapid diagnosis in the future (Reibel et al., 2023).
    1. Multidrug Therapy (MDT)The World Health Organization (WHO) provides free multidrug therapy (MDT) for leprosy, which has been highly effective in treating the disease. MDT includes a combination of rifampicin, dapsone, and clofazimine, which has successfully reduced the global burden of leprosy.
  • Adherence to Treatment: A key challenge in managing leprosy is ensuring patient adherence to the MDT regimen, which may last for several months or even years. Non-adherence can lead to drug resistance, relapse, and continued transmission of the disease. In some studies, patient education and community support systems have been shown to improve treatment adherence (Martins et al., 2022). Innovative solutions such as directly observed therapy (DOT), where healthcare workers ensure that patients complete their treatment, have been implemented in several countries (Lima et al., 2020).
  • Access to MDT: While MDT is widely available, distribution challenges persist in remote and underserved areas. Programs that involve local health workers and community volunteers in MDT distribution and patient follow-up have demonstrated success in improving access to treatment (Santos et al., 2021).
    1. Rehabilitation and Disability PreventionLeprosy can cause irreversible disabilities, especially if not treated early. Disability management is a critical component of leprosy care, as it helps reduce the long-term social and economic consequences of the disease.
  • Early Intervention for Nerve Damage: Rehabilitation programs focusing on preventing nerve damage and managing sensory loss are integral to leprosy management. For example, wearing protective footwear can prevent ulcers and injuries in patients with nerve damage (Pereira et al., 2018). Regular monitoring and physiotherapy also play essential roles in improving the quality of life for leprosy patients.
  • Peer Support and Rehabilitation Centres: Several countries have implemented rehabilitation centres where patients can receive not only physical care but also psychological support. These centres often provide occupational training and psychosocial counselling, helping patients reintegrate into society. Peer support, where individuals affected by leprosy mentor others, has proven to be an effective tool in reducing the social stigma associated with the disease (Banik et al., 2020).
    1. Psychosocial Support and Stigma Reduction:Leprosy remains heavily stigmatized in many cultures, which leads to isolation, discrimination, and poor mental health outcomes for affected individuals. Combating this stigma is a vital aspect of leprosy management.
  • Community Education and Awareness: Increasing awareness about leprosy is crucial in reducing stigma. Public health campaigns that provide information on the disease’s causes, symptoms, and treatment options can challenge misconceptions and promote inclusion. In India, for example, community education programs have been successful in reducing stigma and encouraging people to seek treatment (Chakravarty et al., 2021).
  • Psychosocial Support Services: In addition to medical care, leprosy patients often need mental health support due to the emotional toll of the disease. Several programs have integrated mental health services into leprosy care, offering counselling and support groups. Research suggests that these services significantly improve the overall well-being of patients (Ravindran et al., 2022).
    1. Integrated Healthcare Approaches and Policy FrameworkIn many developing countries, leprosy is just one of several public health issues competing for limited resources. Therefore, an integrated healthcare approach that combines leprosy care with other infectious diseases and health interventions is necessary for efficient disease control.
  • Integration with Other Health Programs: Studies have found that integrating leprosy care into general healthcare services, such as primary healthcare or maternal and child health programs, improves the sustainability of leprosy management. This integration can lead to more efficient use of resources and improved access to care (Mehta et al., 2020).
  • Government and NGO Collaboration: In countries like Brazil and Indonesia, collaboration between government agencies, non-governmental organizations (NGOs), and international partners has strengthened the leprosy control program. This multi-stakeholder approach has been key to ensuring the continuity of care, particularly in rural and underserved regions (Mello et al., 2021).

Challenges and Barriers

  • Lack of Awareness and Education: Many people in endemic regions remain unaware of leprosy, its symptoms, or the availability of treatment. Misconceptions about the disease often result in delayed diagnosis and treatment, leading to avoidable complications.
  • Healthcare System Limitations: In many developing countries, the healthcare system is often underfunded and lacks the infrastructure needed for effective leprosy management, such as diagnostic tools, adequate training for health workers, and sufficient medicine supply. Discussions with the management of the Leprosy Mission Abuja revealed challenges in accessing treatment drugs through the National Agency for Food and Drug Administration and Control (NAFDAC), despite provisions by the World Health Organization (WHO) for these medications to be freely available.
  • Social Stigma: Leprosy is often associated with negative social stigma, which can prevent patients from seeking care and participating in rehabilitation programs. Fear of discrimination can also lead to patients abandoning their treatment.

The Marginalization of Individuals with Leprosy in Developing Countries

Individuals affected by leprosy in developing countries often face significant social exclusion, leading some scholars to describe them as a “forgotten tribe.” Historically, leprosy has been associated with myths, fear, and stigma, resulting in forced segregation and discrimination (Chakravarty et al., 2021). Despite medical advancements and the availability of free multidrug therapy (MDT) provided by the World Health Organization (WHO), many individuals continue to suffer from social isolation, economic marginalization, and limited access to healthcare services (Banik et al., 2020). In some communities, leprosy-affected individuals are abandoned by their families or struggle to find employment due to persistent prejudice (Ravindran et al., 2022).

The lack of awareness and continued stigma prevent many from seeking early treatment, exacerbating disability and social exclusion (Martins et al., 2022). Addressing this issue requires sustained community engagement, awareness campaigns, and policy interventions driven by the government and aimed at reintegrating affected individuals into society and ensuring their fundamental rights are protected.

Conclusion

Leprosy management in developing countries requires a comprehensive approach that goes beyond medical treatment to include early detection, rehabilitation, and the reduction of social stigma. While multidrug therapy (MDT) provided by the World Health Organization (WHO) has significantly reduced the disease burden, challenges remain in ensuring timely diagnosis, treatment adherence, and accessibility in remote areas. Moreover, individuals affected by leprosy often experience severe marginalization, reinforcing their status as a “forgotten tribe” within society. The stigma associated with leprosy leads to social isolation, economic hardship, and psychological distress, making reintegration into society particularly difficult (Banik et al., 2020; Chakravarty et al., 2021). Addressing this issue requires sustained community-based interventions, public awareness campaigns, and inclusive policies that promote social acceptance and equal opportunities for affected individuals.

Collaboration among governments, non-governmental organizations (NGOs), and local communities remains essential in tackling both the medical and social challenges of leprosy. Integrated healthcare approaches that combine leprosy management with broader public health initiatives can enhance resource efficiency and improve patient outcomes. Furthermore, psychosocial support programs and stigma-reduction strategies are critical in ensuring that individuals affected by leprosy receive not only medical care but also the dignity, respect, and social inclusion they deserve. Ultimately, a holistic and sustained commitment to leprosy control is necessary to eliminate the disease and restore the rights and well-being of those affected.
