为了消灭阳山县丝虫病 ,从 1 959年起对该县进行丝虫病流行病学摸底调查 ,发现共有 1 9个乡镇的 2 1 7个管理区有班氏丝虫病流行 ,平均人群微丝蚴率为 4 3 5%。据此提出以防治病原为主导的策略 ,制订出三项防治技术措施 :①在一个中度流行镇以海群生间歇双疗程法进行连续四年反复查治 ,微丝蚴率从查治前的 1 5 0 8%降至 0 4 5% ;②对连成一片且有固定食盐供应渠道的三个中度流行镇采用全民服食海群生掺拌食盐 ( 3g/kg)防治 6个月 ,微丝蚴率从 5 0 7%降至 0 4 3 % ;③查治结合重点村全民服药 ( 7岁以上人群全民用海群生 3g ,5天分服 ) ,共血检 1 3 2 58人 ,查出并治疗微丝蚴血症 1 5例 ,全民服药 1 8757人 ,巩固丝虫病防治效果。 1 980年经卫生部考核 ,微丝蚴率降至 0 0 0 %～ 0 2 5% ,达到基本消灭丝虫病标准。 1 988～ 1 992年进行纵向监测和 1 9个乡镇横向监测分别血检 60 85、2 80 1 2人次 ,均未发现微丝蚴血症者 ;分别解剖致倦库蚊 1 0 545、4 61 6只 ,均未发现有丝虫感染。 1 996年经省及卫生部考核达到消灭丝虫病部颁标准
In order to eradicate filariasis in Yangshan County, an epidemiological investigation of filariasis was conducted in the county from 1959. It was found that there were Bancroftian filariasis epidemics in 21 of the 19 townships, and the average population Microfilaria rate was 43.5%. Accordingly, the strategy of prevention and treatment of pathogen is put forward and three prevention and control measures are formulated: ① In a moderately popularized town, repeated quarantine treatment is carried out for four consecutive years with intermittent double-sea treatment by seaquakes. The rate of microfilariae from the pre- 15.8% to 0 45.5% respectively; (2) Three moderately populated towns with integrated salt supply with sea salt (3g / kg) The rate of silkworm larvae dropped from 57.07% to 43.3%. ③The combination of investigating and treating patients in key villages (3g, 5 days for common people over the age of 7) Fifteen cases of microfilaremia were treated and treated, and 18,757 people were given medication for the whole nation to consolidate the prevention and control of filariasis. 1 980 By the Ministry of Health assessment, microfilariae rate decreased to 0 0 0% ~ 0 25%, to basically eliminate filariasis standard. Longitudinal monitoring from 1988 to 1992 and lateral monitoring from 19 villages and towns were performed respectively on a blood test of 60 85,280 1 2 and no microfilariae were found. Culex pipiens pallens were dissected 1 0 545,461 6, all found no filarial infection. In 1996 by the provincial and ministry of health examination to eliminate filariasis ministerial standards
