每年7-11月间,农村中常常出现这样一种病:病人突然发烧、头痛、肌肉酸痛,尤以小腿肌肉疼痛得更明显。有的还出现腹痛、呕吐、眼结膜充血、巩膜和皮肤发黄,严重的还会咯血、呕血,甚至昏迷不醒等。这就是钩端螺旋体病。因多在农村收割水稻季节发生与流行,所以又叫“打谷黄”病。 Between July and November each year, a disease often occurs in rural areas: the patient suddenly has fever, headache, and muscle aches, especially in the calf muscles. Some also appear abdominal pain, vomiting, conjunctival hyperemia, sclera and skin yellow, severe hemoptysis, hematemesis, and even unconscious. This is leptospirosis. Due to the occurrence and prevalence of more rice harvest in the countryside, it is also called “threshing yellow” disease.
