回答(1):

上面的说的没错,血吸虫病是通过尾蚴(血吸虫幼虫的一个阶段)进入皮肤和粘膜感染人体的。所以感染需要的条件你并没有,可以放心!
所谓感染条件,简单通俗一点归纳就是:
1,某水体有已患有血吸虫病的人的粪便,并且粪便上有虫卵。 你的同事已经好了,它的粪便就不再有虫卵了。
2,水体有钉螺(只能是钉螺,一般湖南地区较多),并且虫卵被他吃进而繁殖成一定阶段。
3,你接触到这水(医学上称疫水)特别是指缝和趾缝
有些不大记得了,但是我想你应该是不会全部满足这些的,所以大可以放心了,别因为这事和同事有了矛盾。加油。

回答(2):

血吸虫病是传染病,但不同的传染病都有特定的传播途径,血吸虫是病人体内的虫卵,成虫的卵经血流到肠避,释放的酶会破坏肠避,形成溃疡,虫卵随粪便排出体外。
随排便将虫卵入水,虫卵在水中孵化成毛蚴,钻入钉螺发育成尾蚴,在水中释放出形成疫水,具传染性。当人在水中,尾蚴钻入皮肤,经过移行,最终到肠系膜发育成成虫,由此可见在一起生活是不会传染的。

回答(3):

血吸虫病是一种人和动物都能受传染的寄生虫病。

人感染血吸虫的途径主要有两类。一类是生产性感染,如在疫水中耕耘、插秧、捕鱼、割水草、打粽叶以及防汛、排涝等水中作业。一类是生活性感染,如在河、沟、湖疫水中淘米、洗菜、洗手脚、喝生水、游泳等。

血吸虫病传播有一定周期。当血吸虫卵随病人、病畜的粪便排出体外后,在水中孵化出毛蚴,毛蚴钻入钉螺体内,经过一段时间繁殖,释放出成千上万条尾蚴。此时,如果人、畜接触了这种疫水,尾蚴就会通过皮肤和粘膜钻入人、畜体内并变成童虫,再经过在体内移行,最后在肠系膜静脉血管里定居,发育成为成虫。成虫产卵,一部分虫卵又随粪便排出体外。这就形成了血吸虫病传播的一个周期。

血吸虫病尽管人、畜都能感染,但病人、病畜与健康人、畜之间,是不会直接传播的。

回答(4):

血吸虫病是血吸虫寄生于人体或者哺乳动物体内引起的疾病,是一种人畜共患病。所以,如果有恰当的途径,血吸虫病还是可以传染给人的。但是也并不能直接感染人,因为血吸虫在自然界还需要在钉螺体内发育。转染是接收和表达噬菌体,外源DNA是噬菌体的DNA。转染有好多方法:电转、瞬时转染、稳转、磷酸钙转染,我们实验室平时使用RFect-siRNA进行转染实验。

楼主:

血吸虫是通过疫水进入人皮肤而感染的;

病人、病畜与健康人、畜之间,是不会直接传播的;

祝健康
