Echinococcosis is a **parasitic infection** caused by tapeworms of the genus *Echinococcus*, primarily *E. granulosus* (cystic echinococcosis) or *E. multilocularis* (alveolar echinococcosis). It is characterized by the formation of cysts, often in the liver and lungs, and is most prevalent in rural, pastoral regions where dogs and livestock interact.

It can change overnight. Be the first to know when it does.
Echinococcosis has been recognized since ancient times, with descriptions of 'water bladders' in human organs dating back centuries. The tapeworm *Echinococcus granulosus* was formally identified in the 18th and 19th centuries, leading to a better understanding of its complex life cycle involving dogs and livestock. This historical knowledge was crucial for developing public health strategies to control the disease.
Humans become infected with echinococcosis by accidentally ingesting microscopic *Echinococcus* eggs. These eggs are shed in the feces of infected definitive hosts, such as dogs, wolves, or foxes. Transmission occurs through direct contact with infected animals, or by consuming contaminated food, water, or soil containing the eggs.
