About 500 million people
(globally 2 billion) are chronically infected with STH in the South-East Asia
Region and all 11 countries are endemic. School-aged children and the women
of child bearing age are at the highest risk of consequences from these
infections.
The common soil-transmitetd
human helminths in the Region are roundworms (Ascaris lumbricoides), whipworms (Trichuris trichiura)
and hookworms (Necator
americanus & Ancylostoma
duodenale).
Infection rates differ according to ecology but in some
countries, are as high as 95% in some ecological areas.
