泡型包虫病由多房棘球绦虫的幼虫感染所致。是阿拉斯加西北部沿海地区的地方性流行病。自1947年在该地区首次报道以来,已经确诊了50例。全部病例均来自阿拉斯加州8个村庄总人口不到4000人的爱斯基摩人。一些早先的病例通常在患者出现感染的症状或体征后,外科才作出本病的诊断。多数近期的病例是通过对高危险村庄的居民所作的血清学普查而确诊。 Bubble hydatid disease is caused by larvae of Echinococcus multilocularis. Is a endemic epidemic in the northwestern coast of Alaska. Since its first report in the area in 1947, 50 cases have been diagnosed. All cases were from Eskimos, a total population of less than 4000 people in eight villages in Alaska. Some earlier cases usually make the diagnosis of the disease after the patient has developed the symptoms or signs of infection. Most recent cases have been diagnosed by serological screening of residents in high-risk villages.
