This paper reports the results of an epidemiological survey of intestinal helminths in a village on Kar Kar Island, Madang Province. Samples of blood and faeces were collected from 320 people from all age-groups living in 51 houses in Kaul village. Three helminth species were recorded: Ascaris lumbricoides infections were highest and heaviest in childhood, and fell to low levels in adult life, the overall infection rate being 57%. More than 70% of the adult population were infected with Necator americanus, though almost all infections were light. 21% were infected with Trichuris trichiura, and all infections with this species were light. The parasitological findings were related to the haematological results, and the social and physical environmental factors affecting these findings are discussed. It is concluded that Ascaris infection is the principal cause of the high eosinophilia in the community.
本文报告了在马当省卡尔卡尔岛一个村庄进行的肠道蠕虫病流行病学调查结果。从考尔村51所房屋中所有年龄组的320人采集了血液和粪便样本。记录到三种蠕虫：蛔虫感染在儿童期最高且最严重，成年后降至低水平，总体感染率为57%。超过70%的成年人口感染美洲板口线虫，不过几乎所有感染都很轻微。21%的人感染了鞭虫，且该种感染均很轻微。文中讨论了寄生虫学发现与血液学结果的关系，以及影响这些发现的社会和自然环境因素。得出的结论是，蛔虫感染是该社区嗜酸性粒细胞增多症高发的主要原因。
