Since then, donors have made significant
commitments, drug donation programs have been set up, and national
governments in endemic countries have shown their engagement in
implementing and scaling up activities to control and eliminate NTDs in
general and STH in particular.
As a result of this global effort, the number of children receiving PC for
STH has progressively increased to reach 328 million children in 2010,
14
corresponding to a global 30% coverage. Data show that while coverage of
pre-school-aged children is steadily increasing (
Figure 15.2
), that of
school-aged children is growing at a slower pace and seems to have
reached a plateau (
Figure 15.3
).
A significant boost is, however, expected from 2011
2012 onwards
when the effect of the recent and expanded drug donations will take
place (from 2012, a quantity of 600 million tablets/year of albendazole
400 mg or mebendazole 500 mg will be available for the treatment of
school-aged children in endemic countries). Coverage data for these two
years are not yet available but the significant increase in requests for
donated medicines submitted by endemic countries (
e
150 million tablets
of albendazole or mebendazole in 2012 compared to 2011 data) suggests
