Yekepa是利比里亚北部的一个矿业城市。1960年新建。现有人口16000人,包括1500名移民。它虽然位于超高疟区包围之中,但控制疟疾已获得了成功。然而,靠近该镇周围的村庄仍受到媒介的威胁。控制疟疾的方法,主张定期使用DDT滞留喷洒,机(煤)油定期处理幼虫,对全部人群采用氨酚喹啉每两周一次化学予防。疟疾流行病学调查结果表明,采取措施的地区脾肿率,原虫率分别为11％和13％;未采取防治措施的地区分别为95％和67％。该地区以恶性疟为主。在Yekepa区内未发现成蚊,而对照区室内平均密度3.8,靠近Yekepa农村子孢子率9.2％。主要媒介为冈比亚按蚊,A.fun-estus也有发现。每年每人平均经费(包括全部疟疾防治活动)约4—5美元。
Yekepa is a mining town in northern Liberia. New construction in 1960. The existing population of 16,000 people, including 1,500 immigrants. Although contained in the ultra-malaria zone, malaria control has been a success. However, villages near the town are still at risk from the media. Methods of malaria control were advocated by regularly using DDT retention sprinklers and machine (coal) oil to process larvae regularly, using paracetamol once every two weeks for all populations. The epidemiological survey of malaria showed that spleen and protozoal rates were 11% and 13% respectively in the areas where the measures were taken and 95% and 67% respectively in the areas where no prevention and control measures were taken. The area is dominated by falciparum malaria. Adult mosquitoes were not found in the Yekepa area, while the average indoor density in the control area was 3.8, with a sporulation rate of 9.2% in the rural vicinity of Yekepa. The main medium is Anopheles gambiae, also found by A.fun-estus. Average annual funding per person (including total malaria control activities) is about 4-5 U.S. dollars.
