Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae. If you ingest certain tapeworm eggs, they can migrate outside your intestines and form larval cysts in body tissues and organs (invasive infection). If you ingest tapeworm larvae, however, they develop into adult tapeworms in your intestines.
In 2011 there were in total 19 registered cases of echinococcosis; unspecified, E. granulosus, and E. multilocularis. Incidence was 0.049/100,000. The highest incidence was recorded in Podlaskie district (0.333/100,000). The reported cases occurred in adults between the age of 34 and 74 (average 56.4; median 58), more often in women (incidence 0.055) than in men (incidence 0.043). Incidence of echinococcosis was higher in the country (0.079) than in the city (0.030).
The percentage of reported cases in which the species of a tapeworm was identified was 63%, and within that 42% were infections with E. granulosus, and 21% with E. multilocularis. In 2011 there were two registered cases of cysticercosis and the incidence was 0.005 per 100,000 population. Adult tapeworm infections are treated with anthelmintic medication which is kills parasitic worms and makes the worms pass out of your intestine in your stools.
