The Present Situation of Human Taeniases and Cysticercosis in Asia

Three human Taenia species, Taenia solium, Taenia saginata, and Taenia asiatica, are endemic in rural regions of Asia, with these species sympatrically distributed in parts of Thailand and China. The pork tapeworm, T. solium, is the most pathogenic to humans, causing cysticercosis and neurocysticercosis (NCC). Due to its public health impact, T. solium taeniasis/cysticercosis is one of 17 neglected tropical diseases (NTDs) prioritized by the World Health Organization. In this review, the current status of taeniasis and NCC in several Asian countries will be presented as will possible prevention and control strategies. Among the known T. solium endemic areas in Asia, Bali, Indonesia is of high importance due to the risk of tourists becoming infected. Therefore, special attention will be given to ongoing control initiatives in Bali.
