黑热病亦称内脏利什曼病,原是危害我国人民最严重的五大寄生虫病之一,流行于长江以北的广大农村,涉及16个省、市、自治区。解放前由于缺乏防治措施,黑热病不断蔓延发展,造成大批人群的死亡。新中国成立后,中国共产党和人民政府对人民的疾苦无限关怀,把控制和消灭多种危害?.. Kala-azar, also known as visceral leishmaniasis, was one of the top five parasitic diseases that endangered our people and was endemic to vast rural areas north of the Yangtze River and covered 16 provinces, municipalities and autonomous regions. Because of the lack of prevention and control measures before the liberation, the spread of kala-azar has led to the death of a large number of people. After the founding of new China, the Chinese Communist Party and the people’s government have given infinite care to the suffering of the people and taken control and eliminated many kinds of harm.
