Neglected Tropical Diseases: When Poverty Makes People Sick – And Conventional Medicine Looks Away

Laura Chrobok  14.11.2025

While modern medicine focuses on high-tech innovations, vaccination strategies and molecular therapies, millions of people are still suffering from diseases that barely receive attention. These conditions are neither new nor mysterious—they are well-known and largely man-made. Neglected tropical diseases arise where poverty, malnutrition and poor hygiene meet. But conventional medicine has labeled their treatment unprofitable—which reveals a deeper truth: conventional medicine primarily follows financial incentives.

In this article, we examine why neglected tropical diseases remain under-researched, how economic interests slow medical progress, what this says about our global health system—and how natural approaches often help where conventional medicine turns a blind eye!

 

Neglected Diseases = Neglected People

The World Health Organization currently lists 21 conditions as neglected tropical diseases (WHO, 2024).

Examples of Neglected Tropical Diseases Include:

·       Snakebite envenoming: In rural parts of Africa and Asia, tens of thousands die each year after snakebites because antivenoms are unavailable or unaffordable. Better access to treatment, trained first responders, and reliable supply chains could save countless lives (The Lancet Global Health).

·       Leishmaniasis: Transmitted by sandflies. Some forms attack internal organs, others cause painful skin ulcers. Malnutrition and weakened immunity dramatically increase the risk (Centers for Disease Control and Prevention, CDC).

·       Schistosomiasis: A parasitic worm infection spread through freshwater snails. Anyone washing clothes or bathing in contaminated water can become infected — often resulting in anemia and severe fatigue (CDC).

·       Onchocerciasis (River Blindness): Blackflies transmit microscopic worms that cause intense itching, skin thickening, and progressive damage to the eyes, eventually leading to blindness (CDC).

·       Trachoma: A bacterial eye infection spread through poor hygiene or flies. Repeated infections lead to scarring and, ultimately, blindness. Clean water and face hygiene offer the best protection (CDC).

·       Guinea worm disease: Parasitic infection caused by drinking water contaminated with larvae. Thanks to improved water hygiene and community education, the disease is now close to eradication (The Carter Center).

More than a billion people are affected worldwide. Despite global elimination strategies, progress remains slow.

The reason is simple: there is no money—or rather, no willingness to invest. While billions are poured into high-tech medicine, affected communities are treated with decades-old drugs whose effectiveness is often limited (Policy Cures Research, 2024).

 

When Health Investments aren’t Lucrative

The pharmaceutical industry invests where profitable markets exist—not where human need is greatest. Only a tiny fraction of global R&D funding goes into treatments for neglected tropical diseases. For corporations, developing such drugs simply does not pay off (Policy Cures Research, 2024).

Many required treatments already exist. But without functioning supply chains or proper education, their impact remains minimal. Instead of structural solutions, conventional medicine relies on so-called “mass drug administration programs”—the blanket distribution of old medications to entire populations. A short-term fix that changes little in the long run: people remain sick, but the statistics look better (WHO, 2024).

In many regions, laboratories, diagnostics, and trained personnel are lacking. Diseases that are not documented effectively “don’t exist” on paper. As a result, they get pushed off global priority lists. Reports of progress may look impressive but rarely reflect the real situation (WHO, 2024).

This systematic blindness has consequences. Without data, there is no attention; without attention, no funding; without funding, no cure. Conventional medicine is part of the problem — as are the international structures surrounding it.

 

When Conventional Medicine Stays Silent – And Natural Medicine Works

Across Africa, Asia, and Latin America, traditional healers, community-based health initiatives, and several NGOs integrate time-tested local medicinal plants, herbal applications, and hygiene practices into prevention programs.

Organizations like The Carter Center, founded by former U.S. President Jimmy Carter, use simple, nature-based interventions in their elimination programs for Guinea worm disease and trachoma: clean drinking water, water filters, latrines, community hygiene education, and face-washing campaigns (The Carter Center, 2023).

Médecins Sans Frontières (MSF) / Doctors Without Borders collaborates with local healing traditions in affected areas—for example, in wound care or first aid after snakebites when medical facilities are far away. MSF views these community-based practices as transitional tools that can later be integrated into modern treatment (MSF, 2023).

The World Health Organization runs its Traditional Medicine Programme in collaboration with African and Asian universities to identify effective components of traditional medicine and integrate them into a scientifically evaluated framework (WHO, Traditional Medicine Strategy 2014–2023).

Scientific institutions such as the Bernhard Nocht Institute for Tropical Medicine in Hamburg and the London School of Hygiene & Tropical Medicine conduct field research on how traditional health practices, including hygiene, nutrition, and plant-based knowledge, can complement modern diagnostics and pharmacotherapy. The goal is to understand local healing concepts to enable more effective prevention and health education (BNITM, 2024; LSHTM, 2024).

 

Why Neglecting Neglected Tropical Diseases Can Be a Problem for Everyone

It would be a grave mistake to ignore neglected tropical diseases, because history and current trends show that diseases once confined to remote tropical regions can shift their boundaries—and eventually become a global concern. Dengue fever, for example, has expanded from classic tropical zones into the subtropics and even some temperate regions thanks to urbanisation and the spread of the mosquito Aedes aegypti (WHO, 2024). Chikungunya, similarly borne by Aedes mosquitoes, reached Southern Europe and the Caribbean in major outbreaks—a stark reminder that vector-borne diseases do not respect borders (CDC, 2023).

The message is clear: What remains neglected today can become tomorrow’s challenge across continents. Neglected tropical diseases are not just the burden of the poorest; they are an early warning system. Strengthening prevention, diagnostics and treatment now isn’t just charity—it’s global health security (WHO, Roadmap for Neglected Tropical Diseases 2021-2030).

 

Conclusion: Greed for Profit on One Side, the Power of Nature on the Other …

In many parts of the world, traditional medicine is not just an “alternative”—it is the only option people have. These approaches strengthen prevention, daily health competence, and personal responsibility, addressing the root causes of disease and enabling sustainable recovery.

Natural substances like propolis, and plants such as neem, turmeric, chamomile, and aloe vera, are used successfully for skin and eye infections, wound care, and parasitic issues. Projects that combine water hygiene, nutritional guidance, and natural wound management often achieve more durable results than short-term mass drug programs.

Yet conventional medicine frequently dismisses them as “unscientific”—a very revealing reflex ...

 

FAQ – Frequently Asked Questions About Neglected Tropical Diseases

1. Why are there so few new drugs for neglected tropical diseases?

Because research in this field is not economically profitable. Most affected people live in regions with low purchasing power.

2. Why is the topic barely discussed in Western countries?

Because it offers no immediate profit. Diseases without lucrative markets are considered “not worth the effort.”

3. What role does the WHO play?

It coordinates control and elimination programs, but many goals remain unmet—often due to financial and structural limitations.
