※ 引述《lewdster0128 (熊)》之铭言：
题目
承上题，下列何者是此疾病(salmonella)的主要感染源？
(A)空调系统
(B)长期带原者
(C)地下水
(D)猫狗等宠物
原本答案(B) 建议答案(B)(C)
依照最新医用微生物学
儿童主要是经粪口传染→这样答案是长期带原者
大部分人是经由吃入被细菌污染的食物，也就是被带原者污染过的食物和饮水，
所以带原者只算是污染源，而感染源应该是被污染的食物和地下水吧→答案(C)
因为我不知道怎样申覆比较正确，所以不知道这样申覆可不可以??
还是需要找其他参考资料??
还有请板上的高手给予意见与帮助
谢谢~
美国CDC: How is typhoid fever spread?
Salmonella Typhi lives only in humans. Persons with typhoid fever carry the
bacteria in their bloodstream and intestinal tract. In addition, a small
number of persons, called carriers , recover from typhoid fever but continue
to carry the bacteria. Both ill persons and carriers shed S. Typhi in their
feces (stool).
You can get typhoid fever if you eat food or drink beverages that have been
handled by a person who is shedding S. Typhi or ""if sewage contaminated with
S. Typhi bacteria gets into the water you use for drinking or washing food"".
Therefore, typhoid fever is more common in areas of the world where
handwashing is less frequent and water is likely to be contaminated with
sewage.
Once S. Typhi bacteria are eaten or drunk, they multiply and spread into the
bloodstream. The body reacts with fever and other signs and symptoms.
sewage不知道可以是地下水的意思吗? 美国CDC应该证据力够吧
