Neglected tropical diseases (NTDs) primarily affect populations living in extreme poverty, particularly in tropical and subtropical regions. Despite their profound impact on health and society, NTDs attract significantly less research funding compared to diseases like HIV/AIDS, tuberculosis, and malaria.
In 2021, it was estimated that around 677 million individuals in India needed treatment for various NTDs, including dengue, chikungunya, and snakebite envenoming. Other countries facing severe NTD challenges include Nigeria, Indonesia, Ethiopia, Bangladesh, Congo, Philippines, Tanzania, Uganda, and Pakistan.
The year 2022 saw a staggering $4.22 billion allocated for COVID-19 research. In contrast, funding for HIV/AIDS, tuberculosis, and malaria ranged from $600 million to $1.35 billion. Alarmingly, research for NTDs such as dengue, chikungunya, leprosy, and snakebite envenoming received only between $10 million and $80 million.
NTDs contribute significantly to a cycle of poverty, resulting in long-term disabilities, social stigma, and economic burdens. These diseases are responsible for serious health issues, including anemia, blindness, chronic pain, infertility, and disfigurement. Such consequences hinder economic development and deter commercial investments in affected regions.
The burden of NTDs is predominantly experienced in Asia and Africa, with Mexico being the only notable non-Asian, non-African country affected. Deaths associated with NTDs are uncommon in Europe, Oceania, and North America, with the exception of Mexico.
India leads in several alarming statistics concerning NTDs, including dengue fatalities (17,500 in 2019), leprosy cases (over 100,000 in 2022), and snakebite deaths (over 50,000 in 2019).
Recent years have seen most research funding directed towards COVID-19 vaccine development. Unfortunately, funding for new drugs, basic research, biologicals, and diagnostic platforms for NTDs decreased in 2022, further exacerbating the issue.
NTDs pose a significant health burden in Asia and Africa, necessitating increased research funding and global attention. Despite their considerable impact, these diseases remain underfunded relative to other infectious diseases. With enhanced funding and targeted initiatives, as evidenced by the near-eradication of certain diseases, managing and eliminating NTDs is achievable.
Q1. What are neglected tropical diseases (NTDs)?
Answer: NTDs are a group of infectious diseases that primarily affect marginalized populations in tropical and subtropical regions, leading to significant health and social issues.
Q2. Why are NTDs underfunded compared to other diseases?
Answer: NTDs receive less funding due to their prevalence in poorer regions and lack of commercial interest, overshadowed by more prominent illnesses like HIV/AIDS and malaria.
Q3. What is the impact of NTDs on poverty?
Answer: NTDs exacerbate poverty by causing long-term disabilities and social stigma, which hinder economic development and reduce opportunities for affected individuals.
Q4. Which countries are most affected by NTDs?
Answer: Countries like India, Nigeria, Indonesia, Ethiopia, and Bangladesh are significantly impacted by NTDs, experiencing high disease prevalence and related health challenges.
Q5. How can funding for NTD research be improved?
Answer: Increasing awareness, advocating for policy changes, and demonstrating the economic benefits of addressing NTDs can help boost research funding and support.
