我会通过口交感染HIV吗？

通过口交感染HIV的几率非常低，尤其是当HIV阴性的人与HIV阳性伴侣进行口交时。

口交包括用嘴接触阴茎（口交），阴道（舌交）或肛门（肛交）。一般来说，口交传播HIV的风险非常小，几乎没有风险。

然而，一些因素可能会增加通过口交传播HIV的风险。例如，口腔溃疡、牙龈出血、外阴溃疡或其他性传播疾病（STD）的存在，这些可能会增强病毒进入体内的机会。

此外，口交还可能传播其他性传播疾病。比如，肛交时如果口腔接触到粪便，可能会感染甲型和乙型肝炎、贾第鞭毛虫等寄生虫，以及志贺菌、沙门氏菌、空肠弯曲菌、大肠杆菌等细菌。

为了降低通过口交感染HIV或其他性传播疾病的风险，可以采取一些预防措施。详细信息请参考《口交与HIV传播风险》一文。

Can I get HIV from oral sex?

The chance of an HIV-negative person contracting HIV from oral sex with an HIV-positive partner is extremely low.

Oral sex involves placing the mouth on the penis (fellatio), vagina (cunnilingus), or anus (anilingus). In general, there is little to no risk of getting or transmitting HIV through oral sex.

However, certain factors may increase the risk of HIV transmission through oral sex. These include ejaculation in the mouth, oral ulcers, bleeding gums, genital sores, and the presence of other sexually transmitted diseases (STDs), which may or may not be visible.

You can also get other STDs from oral sex. Additionally, if you receive feces in your mouth during anilingus, you could contract hepatitis A and B, parasites like Giardia, and bacteria like Shigella, Salmonella, Campylobacter, and E. coli.
