目的掌握马来丝虫病防治后期的流行病学特征及媒介变化情况,为巩固防治成果,防止丝虫病的再度流行提供科学数据。方法采取查治残存传染源和全民普服药盐的巩固措施;开展丝虫病防治后期病原学、血清学和蚊媒监测及慢性丝虫病调查,并对收集到的资料进行分析。结果东坡区于基本消除丝虫病后的前6年,重点人群监测检出残存微丝蚴血症者7例,其中复阳3例,新检出4例;筠连、雨城区和沐川县于基本消除丝虫病后的前1~5年,横向监测各检出残存微丝蚴血症者2、1和1例,其中原阳拒治者1例,新检出3例中漏查者2例。消除丝虫病后,4个县连续监测14年未检出微丝蚴,无新发慢性丝虫病患者。结论基本消除丝虫病后的初期,丝虫病传播继续存在,采取巩固措施后未检出微丝蚴;消除丝虫病后监测表明,实施不同巩固措施后的远期效果显著。后期工作重点应放在对原慢性丝虫病患者的关怀与照料。
OBJECTIVE To master the epidemiological characteristics and media changes of the late stage of malayian filariasis control and provide scientific data for consolidating the prevention and cure results and preventing the recurrence of filariasis. Methods Consolidation measures of survivors of infection and universal medicine were carried out. Etiological, serological and mosquito vector surveillance and chronic filariasis investigation were carried out in the later stage of prevention and treatment of filariasis. The collected data were analyzed. Results In Dongpo District in the first 6 years after the elimination of filariasis basically, 7 cases of residual microfilaremia were detected in key population, including 3 cases of Fuyang and 4 cases newly detected. Junlian, Yucheng District and Mu Chuanxian in the basic elimination of filariasis after 1 to 5 years, the lateral monitoring of the detection of residual microfilaremia who 2,1 and 1 cases, including one of the original yang rejecting the rule, newly detected in 3 cases Missing investigation in 2 cases. After the elimination of filariasis, four counties did not detect microfilariae for 14 consecutive years, and no new chronic filariasis patients were found. Conclusion In the early period after the basic elimination of filariasis, the spread of filariasis continues to exist. After the consolidation measures, microfilariae are not detected. After the elimination of filariasis, monitoring shows that the long-term effect of the implementation of different consolidation measures is significant. Late focus should be placed on the original care and care of patients with chronic filariasis.
