Introduction 

Elephantiasis, medically known as lymphatic filariasis, is a condition that causes swelling of the tissue in the body. This leads to hardening of the tissues affected and thickening of the overlying skin. Symptoms also include pain, fever and disability.¹ In a healthy body, fluid known as lymph moves throughout the lymphatic system freely to support the body's normal function. Lymph consists of white blood cells, plasma and platelets, which are components of blood. Lymph plays a key role in our immune system and helps our body fight infection. Lymph travels in lymph vessels that transport the fluid through lymph nodes. Lymph nodes monitor the lymph for germs, foreign substances and abnormal cells and remove waste products and bacteria from the lymph.²

Elephantiasis is caused by a parasitic worm called filariae. There are three different species of filariae: Wuchereria bancrofti, Brugia malayi, and Brugia timori. These parasites are spread via mosquito bites.³ Once bitten, the parasite enters the bloodstream, causing the lymph vessels to become inflamed and leading to blockage of the lymphatic vessels, which results in fluid build-up.¹

Infection 

Infections commonly occur in children. Following infection, there is a long period where individuals have no symptoms; they are known as asymptomatic. Symptoms tend to emerge later in life, and clinical manifestations are grouped into categories: acute attacks, elephantiasis and widespread swelling. Although the initial infection can be asymptomatic, it can still cause an impaired immune system that allows for a predisposition to a secondary infection. This causes acute attacks resulting in the characteristic symptoms of pain and swelling, primarily affecting the lower limbs. Chronic infection can lead to ongoing swelling of the limbs and even spread to the genitals, causing a hydrocele, which is a swelling of the scrotum and penis.^1,3 The swelling often causes damage to the skin as it becomes red, thickened and produces sores, which further exacerbate the symptoms of elephantiasis.⁴

Epidemiology

In January 2025, elephantiasis was shown to have affected 120 million people in 72 countries throughout the tropics and sub-tropics of Asia, Africa, the Western Pacific, and parts of the Caribbean and South America.⁷ Predominantly, most cases are seen to occur in India and Africa. In Africa, 39 countries are endemic, where nearly 390 million individuals are at risk of infection.¹²

There is a greater prevalence of elephantiasis in tropical climates. Geographical mosquito populations are higher in these climates. Poor mosquito control, along with poor sanitation and stagnant water, is brought about by poverty, which increases the risk of infection.¹³

Elephantiasis is considered a neglected tropical disease (NTD). NTDs are a condition caused by viruses, bacteria, parasites, fungi and toxins; they are commonly linked to poor health, social and economic consequences. NTDs are commonly presented in impoverished communities.⁵

Although elephantiasis does not commonly lead to mortality, morbidity rates, including disability-adjusted life years (DALYs) and years lived with disability (YLDs), remain high. This causes an extensive burden on affected populations, especially in the midst of poverty.¹⁴ Challenges in disease control include limited healthcare infrastructure and poor access to medical services, which in turn lead to gaps in epidemiological surveillance. These gaps hinder accurate estimation of disease prevalence and burden, as many infected individuals remain undiagnosed and unreported.¹⁵ Mass Drug Administration (MDA) programs have historically been successful in reducing disease prevalence and improving population health outcomes.¹⁶ However, their effectiveness depends heavily on sustained funding, community engagement, and robust health systems.¹⁷

Psychosocial impact 

This article aims to delve deeper into the psychosocial impact of elephantiasis beyond the physical morbidity. The main physical manifestation of elephantiasis is limb swelling, which causes limbs to be deformed and lose function. This loss of function causes physical disability in individuals infected. This has a massive impact on mobility, which reduces the ability to earn a living. Studies showed that 36.2% of participants with elephantiasis could no longer work due to their condition. Many reported a need to depend on others for financial support. This loss of income not only affects the individual but also places financial strain on their families.⁶

Apart from the physical barriers caused by this infection, the visible manifestations can trigger stigma. Cultural beliefs in populations where prevalence is high can lead people to have negative views of those with elephantiasis. Some cultures believe that the cause of their limb swelling was due to witchcraft or evil spirits placed on them. Others made some reference to the cold being the reason for their leg swelling, inferring that their presentation was self-inflicted.⁶

Moreover, the individuals themselves can feel internalised shame, leading to reduced self-worth. This prejudice can affect many areas in the sufferer's life.⁷ As the condition can be chronic, these psychological effects can be present for long periods of time, leading to emotional distress, including depression, anxiety, and hopelessness. A systematic review found that ​​the severity of the disease correlated directly with an increased emotional and social impact.⁹ Individuals may refrain from social interaction. Their education can also be affected as stigma surrounding their appearance causes them to be reluctant to go to school due to the emotional impact. Almost 80% of respondents reported feeling ashamed or stigmatised by their condition. Some said it restricted their social lives and their willingness to go out in public.⁹

Women often face increased discrimination in marriageability. Elephantiasis was shown to reduce a woman's chances of finding a partner and getting married.¹⁰ Many of the reasons for this include perceived and internalised stigma experiences, such as being criticised and isolated by the community, health providers, and even by friends and relatives. In fact, women with elephantiasis found that they were denied access to education and meaningful work roles.¹¹

Strategies and interventions

Though stigma surrounds the visible manifestations of elephantiasis, some strategies exist to aid in reducing this social impact. Community education and awareness programmes aim to dispel myths, reduce misconceptions, and create empathy towards affected individuals. These interventions encourage early healthcare seeking and work to target both patients and the broader community through schools, media campaigns, and local leaders.^18,19 Psychological support services, such as counselling and mental health care, address the emotional distress frequently experienced by patients; Peer support groups offer safe spaces for sharing experiences, reducing isolation, and enhancing coping mechanisms.²⁰

Rehabilitation programs focusing on lymphatic care, hygiene education, lymphatic drainage, and exercise improve physical symptoms. This has been shown to enhance self-esteem, facilitating greater social participation and improved quality of life.⁸ Fostering resilience helps individuals adapt positively despite stigma and social exclusion, ultimately improving mental health and wellbeing.⁹ Community-led support groups and patient advocacy initiatives are vital for empowering affected individuals. They promote self-efficacy, advocate for improved healthcare access, and influence policy. Patient networks in endemic regions have successfully mobilised resources, raised awareness, and contributed to social integration for people with lymphatic filariasis.^21,22 Combining education, psychosocial support, and community empowerment is crucial for combating stigma and enhancing patient outcomes in elephantiasis care.

Summary 

Elephantiasis is a complex disease that affects more than just the physical body. The visible swelling and deformity cause significant disability, which limits mobility and the ability to work, leading to economic hardship. This is often worsened by stigma, rooted in cultural beliefs and misconceptions about the disease. Stigma causes social isolation and psychological distress, making it harder for patients to access care and support.¹⁰ To effectively address elephantiasis, interventions must go beyond medical treatment to include psychosocial support, community education, and patient empowerment.

Community-led education and advocacy are important for changing negative cultural beliefs and reducing stigma. These efforts help affected individuals feel accepted and encourage early treatment, which can prevent further disability. Strengthening health systems to provide ongoing morbidity management and mental health services is also critical to support long-term care. Rehabilitation and peer support programs help patients improve their quality of life and regain independence. Additionally, economic support initiatives can reduce the financial burden and improve social inclusion. Overall, a comprehensive approach that addresses both the physical and social impacts of elephantiasis is needed to improve outcomes and move closer to disease control and elimination.
