近来,从期刊、报纸上,常常看到某些传染病被消灭了的报道,颇有所感,愿意发几句议论。从地球上,从我们国家里,消灭了某种传染病,当然是值得高兴的事情。问题是某种曾报道被消灭了的传染病,事隔两年,又在这地区或那地区漫延传播开来,危害人类,这就不能不引起人们的注意:在宣布传染病消灭的问题上,我们应该采取十分慎重的态度。宣布一种传染病的消灭,要有充分的根据。调查地区范围的大小,调查数据的多少,病人、病原体、动物及媒介昆虫宿主和自然环境等方面资料的确切性,调查方法的周详和严密性等等,都要影响到结论的正确性和可信程 Recently, there have been quite a few reports from journals and newspapers that often see the disappearance of certain infectious diseases. They are willing to make a few comments. It is of course something deserving of pleasure to have eradicated some infectious diseases from our planet and from our own country. The problem is that some kind of contagious disease that has been reported to have been eradicated spreads over two years and spreads in this area or in the region, endangering mankind, which can not but draw the attention of people: on announcing the elimination of infectious diseases We should take a very cautious attitude. To declare the eradication of a contagious disease, there should be sufficient basis. The size of the survey area, the number of survey data, the exact nature of the data on patients, pathogens, animal and insect hosts and the natural environment, the thoroughness and rigor of the survey methods, etc., all influence the correctness of the conclusions Credit process
