前言人们认为麻风起源于热带和亚热带地区,这些地方的麻风已有两千年的历史。此地区的许多国家经济不发达,可能是麻风继续高度流行的原因。流行病学情况世界卫生组织(WHO)于1966、1972和1976年所做的全球性调查表明,过去十年中,非洲麻风病人数未见增加,估计仍在350-400万之间,占全世界估计麻风病人总数的34％,亚洲病人占总数的62％,南美占3％,其余地方只占1％。虽然亚洲麻风病人数最多,但按陆地面积计算,非洲的流行率比亚洲高三倍。非洲的麻风主要分布在西部、中部和东部的热带、亚热带,北部和南部很少。在这些流行区,流行率介于2.8-7.4‰之间,平均为6‰(见表1)。
Introduction Leprosy is thought to originate in the tropical and subtropical regions, where leprosy has been 2,000 years old. Underdevelopment in many countries in the region may be the reason why leprosy continues to be highly prevalent. Epidemiology The global survey conducted by the World Health Organization (WHO) in 1966, 1972 and 1976 showed that in the past 10 years, the number of leprosy patients in Africa has not increased, and it is still estimated at between 3 and 4 to 4 million The world estimates 34% of leprosy patients, 62% of Asian patients, 3% of South America, and 1% of the rest. Although the number of leprosy patients in Asia is the largest, the prevalence in Africa is three times higher than that in Asia, by land area. Leprosy in Africa is mainly distributed in the western, central and eastern tropical, subtropical, northern and southern rarely. In these endemic areas, the prevalence ranged from 2.8 to 7.4 ‰ with an average of 6 ‰ (Table 1).
