古人云:“水至清则无鱼。”凡有鱼的河、塘、湖、水库,其水中浮游生物必然很多。而这些水,很可能受到鼠、猪、蛙、鱼、蛇及其它动物的尿液污染。根据我国流行病专家研究,在这些动物的尿液中,50％以上含有“致病性钩端螺旋体”,在25～30℃的气温条件下,能生存一个半月至半年,对垂钓者威胁极大。每年八九月份是“钩体病”的发病高峰。倘若在此期间垂钓,人脚不慎接触了含有“钩体”的疫水,“钩体”便会从破损的皮肤或粘膜钻进人体内,迅 The ancients said: “no water to the clear fish.” Where there are fish river, pond, lake, reservoir, the plankton must be a lot of its water. This water is likely to be contaminated with urine from rats, pigs, frogs, fish, snakes and other animals. According to epidemiological experts in China, more than 50% of the urine of these animals contain “pathogenic Leptospira,” which can survive from one and a half months to six months at 25-30 ° C, Big. August and September each year is the “incidence of Leptospirosis” peak. If fishing during this period, human foot inadvertently contact with the “hook body” of the water, “hook body” will be from the damaged skin or mucous membrane into the body, quickly
