棘球蚴病（英文：Echinococcosis）也被称作包虫病（英文：hydatid disease），是一种可以影响人类和其他如羊，狗，老鼠和马等哺乳动物的寄生虫病。 在人类**发现三种不同形式的棘球蚴病，每一种病分别由不同物种的细粒棘球绦虫属的绦虫的幼虫所引起的。在人类中发现的该病的第一位是囊型棘球蚴病（又称囊型包虫病），是由细粒棘球蚴所引起的。第二位是泡球蚴病（又称泡型包虫病），是由滤泡棘球蚴所引起的。

发病后，患者的症状和体征取决于包虫的位置和大小。泡型棘球蚴病通常发病于肝脏，之后也有可能扩散至肺部和脑部等其它部位。肝脏发生病变后，患者的临床体征可能包括腹痛，体重减轻，和黄疸等。肺部病变可能导致胸口疼痛，气短，和咳嗽。

Echinococcosis, also called hydatid disease, hydatidosis, or echinococcal disease, is a parasitic disease of tapeworms of the Echinococcus type. The two main types of the disease are cystic echinococcosis and alveolar echinococcosis. Less common forms include polycystic echinococcosis and unicystic echinococcosis. The disease often starts without symptoms and this may last for years. The symptoms and signs that occur depend on the cyst's location and size. Alveolar disease usually begins in the liver but can spread to other parts of the body, such as the lungs or brain. When the liver is affected the person may have abdominal pain, weight loss, and turn slightly yellow from jaundice. Lung disease may cause pain in the chest, shortness of breath and coughing.
