Annual economic loss caused by Taenia saginata asiatica taeniasis in three endemic areas of east Asia.
The Taenia saginata-like tapeworm in East Asia has been designed as a separate subspecies of T. saginata. It was named as T. saginata asiatica and the classical T. saginata as T. saginata saginata. In the course of conducting experimental infections and morphological studies, a large number of adult worms of T. saginata asiatica was collected. It is possible to estimate the annual economic loss caused by this infection, since the worm load and the weight of worm habored by each infected person were determined from the collection. In the mountainous areas of Taiwan, the infection rate of T. saginata asiatica taeniasis was 11.0%, the worm load was 1.6 worms/case, and the average weight of an adult worm was 20.5 g. The annual economic loss was estimated to be US$ 11,327,423. On Cheju Island of Korea, the infection rate was 6.0%, the worm load was 2 worms/case, and the average weight of an adult worm was 19.3 g. The annual economic loss was estimated to be US$ 13,641,021. On Samosir Island of Indonesia, the infection rate was 21%, the worm load was 1.8 worms/case, and the average weight of an adult worm was 22 g. The annual economic loss was estimated to be US$ 2,425,500. These figures indicate that taeniasis is not only a significant public health problem but also an important economic problem in East Asia.
