软性下疳  I

1.它是什么？
软性下疳是一种性接触传播的细菌性传染病。在发展中国家比发达国家更普遍。但是，随着当今不断增加的旅游交往，它偶尔波及富裕的西方社会。为了将它与梅毒的“硬下疳”相区别，这种传染病也就称为“软性下疳”了。

2.它由什么所引起？
软性下疳由杜克雷嗜血杆菌（haemophilus ducreyi）感染所导致。

3.它如何传播？
该传染病通过性接触传染，也就是阴道性交、口交和肛交都可以传染该病。在一些西方国家，它主要由性工作者传染给顾客。未做包皮环切术的男性比做过环切术的男性会冒更大的风险。当分娩时，母亲也能够将病菌传染给她的新生宝宝。如果对感染的有孕母亲做剖腹产，能够降低新生宝宝感染的风险。

Chancroid I

1. What is it?
Chancroid is a sexually transmitted bacterial infection. It is much more common in developing than in developed countries. However, with today’s increasing international travel, it occasionally reaches richer Western societies. The disease is also called "soft chancre" to differentiate it from the "hard chancre" of syphilis.

2. What causes it?
Chancroid is caused by the bacterium haemophilus ducreyi.

3. How is it transmitted?
The disease is spread by sexual contact, i.e. vaginal, oral, and anal intercourse. In some Western countries, the infection is transmitted mainly by sex workers to their clients. Uncircumcised males run a greater risk of infection than circumcised males. The bacterium can also be transmitted by a mother to her baby while she is giving birth. The risk can be reduced if the baby of an infected mother is delivered by Caesarian section.
