Why are they Neglected?
 Neglected tropical diseases blight the lives of 1 billion
people worldwide and threaten the health of millions
more.
 They are named neglected because these diseases
persist exclusively in the poorest and the most
marginalized communities, and have been largely
eliminated elsewhere and thus are often forgotten.
Those affected are poor and have little political voice.
 The diseases don't tend to spread to distant countries
and only rarely affect travelers
NTDs
 For some NTDs, there are simple tests which cost as little as

four cents.
For some, the currently available diagnostic tools require
skilled health workers and hospitalization.
People in remote areas often become ill or die before the
disease can be diagnosed.
Medicines for some NTDs are safe, inexpensive or even
distributed free. They can be administered by nonmedically trained staff like teachers
However, for some, there are expensive medicines that
must be administered by a medical professional or no
medications at all.
Eradication and Elimination
 Control-The reduction of disease incidence, prevalence,

morbidity or mortality to a locally acceptable level as a result of
deliberate efforts; continued intervention measures are required
to maintain the reduction. Example-diarrhoeal diseases
Elimination-Reduction to zero of the incidence of a disease in a
defined geographical area as a result of deliberate efforts;
continued intervention measures are required. Examplesneonatal tetanus, measles, polio
Eradication-Permanent reduction to zero of the worldwide
incidence of infection caused by a specific agent as a result of
deliberate efforts; intervention measure are not longer needed.
Smallpox is the only disease that infects humans ever to have
been eradicated. Infectious agent exists in a laboratory.
Extinction-The specific infectious agent no longer exists in
nature or in the laboratory. Example-none
Indicators of Eradicability
 An effective intervention is available to interrupt
transmission
 No animal reservoir
 Straightforward to diagnosis
 The success of a disease eradication initiative is largely
dependent on the level of societal and political
commitment to it from the beginning to the end
