Sparganosis in mainland China

Sparganosis is an infection of humans and animals caused by the plerocercoid larvae (spargana) of various diphyllobothroid tapeworms belonging to the genus Spirometra. Sparganosis has been reported sporadically around the world, and a higher prevalence of the disease occurs in several Asian countries, including South Korea, Japan, Thailand, and China. To date, a total of more than 1000 cases of human sparganosis have been reported in 25 provinces in mainland China. Sparganosis is emerging inmainland China because of food consumption habits and the unusual practice of treating wounds or other lesions with poultices of frog or snake flesh. This article reviews the current status of sparganosis in mainland China. Increased public awareness about the risks associated with eating raw food and strengthened food safety measures are needed.
