Serum samples were collected from 2643 suspected cases of paragonimiasis in 2000-2007 from the outpatient departments of the city hospitals and surrounding areas, and the infection rate in the inhabitants, the first and second intermediate hosts, and animal reservoir hosts were investigated in the historical endemic areas. Serum samples were detected and 417 were found antibody positive (15.8%). Among residents in the historical endemic areas, the seropositive rate was 3.1% (46/1462), 2.8% (18/649) and 3.2% (26/813) in males and females respectively (CHI2 = 0.1833, P > 0.05). The infection rate in first intermediate host (snails), second intermediate host (crabs) and animal reservoir hosts was 0.05% (9/ 19,368), 31.1% (15,627/ 50,313) and 11.9% (52/438) respectively. Evidently, natural nidi for Paragonimus spp. still exist in Ningbo City.
2000年至2007年期间，从市医院及周边地区的门诊部收集了2643例疑似肺吸虫病病例的血清样本，并对历史流行区居民、第一和第二中间宿主以及动物储存宿主的感染率进行了调查。对血清样本进行检测，发现417例抗体呈阳性（15.8%）。在历史流行区居民中，男性和女性的血清阳性率分别为3.1%（46/1462）、2.8%（18/649）和3.2%（26/813）（χ2 = 0.1833，P > 0.05）。第一中间宿主（蜗牛）、第二中间宿主（螃蟹）和动物储存宿主的感染率分别为0.05%（9/19368）、31.1%（15627/50313）和11.9%（52/438）。显然，宁波市仍存在肺吸虫属的自然疫源地。
