FACT: One billion people are victims of tropical diseases that could be easily
treated but are neglected because they do not kill rampantly and quickly.
The Problem
Many tropical diseases are left untreated. The people who suffer from
them are also ignored, often shunned because of the disabling and
disfiguring nature of the diseases and far from the attention of the
international community. What’s more, Neglected Tropical Diseases
(NTDs) are most prevalent in areas that are disregarded, such as urban
slums, conflict zones or remote, rural areas.¹
Some of the most prevalent NTDs are treatable at low
cost. An inexpensive combination of four drugs that
costs approximately 50 cents a person a year treats
seven NTDs. A growing body of evidence shows that NTD
victims are more likely to be infected by HIV/AIDS and experience
more severe consequences from malaria infection, so their treatment
can reduce malaria’s effects and HIV/AIDS transmission.
These nearly 30 diseases thrive in hot and humid climates and are
most often spread by worm parasites in contaminated water. They can
be incredibly stigmatizing: River blindness, for example, causes lesions
in the eyes and skin and can lead to loss of sight. Elephantiasis blocks
the lymph system and causes parts of the body to severely swell, eventually
immobilizing the person infected.
NTDs fuel a cycle of poverty difficult to escape because they affect
more than just health. They create an enormous burden of poverty
by pulling children out of school and adults out of the workforce. The
result of having hookworm, for example, is estimated to reduce a person’s
future earnings by 40 percent.² Altogether, NTDs have a global
burden that is more than half of that of HIV/AIDS, tuberculosis and
malaria.³ Attention to NTDs is growing steadily, creating an immense
opportunity for donors to have a significant impact on global health.
The Opportunity
Seek programs that focus on prevention and treatment as well
as public-private partnerships. Effectively tackling NTDs requires
a comprehensive approach. Partnerships between organizations
delivering treatment, research institutes, pharmaceutical companies
and government bodies are crucial. Between 1999 and 2006, a partnership
between Pfizer and the International Trachoma Initiative led
to dramatic reductions in infection rates in countries where blinding
trachoma was endemic. Today, the recently formed Global Network
for Neglected Tropical Disease Control is serving as a key partnership
bridging research, nonprofit, and international organizations,
in association with the World Health Organization, to control NTDs
through a global effort.4
Support mapping the disease burden. An immense opportunity
is funding mapping of NTDs in developing countries, particularly
in Sub-Saharan Africa and Asia. With a better understanding of
the disease burden, the global community will be better informed
about the needs required to address the issue.
Support advocacy for neglected tropical diseases. Addressing
NTDs begins with advocating for greater attention from individuals,
donors, government and the private sector to how these diseases
adversely affect the world’s poorest people and how cheaply they
can be treated.
