如果没有一个好的避免传染的方法，我在生孩子之前不会和妈妈同住的。

生殖器疱疹
　　生殖器疱疹是主要由单纯疱疹病毒II（HSVII）引起的性传播 病。在西方国家其发病率仅次于淋病和非淋菌性尿道炎，。本病发病率高，可通过胎盘及 产道感染新生儿，导致流产及新生儿死亡，与宫颈癌的发生也有关，危害较大，已受到人们的重 视。
　　[病因]
　　HSV-2则是生殖器疱疹的主要病原体（90％），存在于皮肤和粘膜损害的渗出液、精液、前列 腺分泌液、宫颈、阴道分泌液中，主要通过性交传染，引起原发性生殖器疱疹。原发性生殖器疱疹消退后，残存的病毒经周围神经沿神经轴长期潜存于骶神经节，当 机体抵抗力降低或某些激发因素如发热、受凉、感染、月经、胃肠功能紊乱、创伤等作用下，可使体内潜伏的病毒激活而复发。人类是疱疹病毒的唯一宿主，离开人 体则病毒不能生存，紫外线、乙醚及一般消毒剂均可使之灭活。

 那就是说妈妈来没有问题，不会传染

STD是英文sexually transmitted diseases的缩写词，意思是性传播疾病。以前我们将这类疾病称为性病，指通过性行为而传播的疾病，比如梅毒、淋病、软下疳、性病性淋巴肉芽肿，它们 被称为"经典性病"。20世纪70年代后，将与性行为相关的疾病统称为性传播疾病，将性病家族从原先的4个成员扩大到20多个，增加了非淋菌性尿道炎、生 殖器疱疹、尖锐湿疣、念珠菌性阴道炎、滴虫性阴道炎、细菌性阴道病、阴虱病、乙型肝炎及艾滋病等 等。（我们在临床上为了方便，仍使用性病这一较为简便的名称，但其涵盖了性传播疾病所包括的范畴）。新近认为，引起性传播疾病的病原体感染后，并非总是引 起有临床表现?quot;疾病"，相反，感染者多数并没有症状，但这种带菌或亚临床状态仍有传染性，或者仍可能对机体造成潜在病变，因此，不可忽视。这 样，最近提出了性传播感染这一概念，包含了有症状的"疾病"与无症状的"感染"。性传播感染的英文为sexually transmitted infections，缩写为STI。
    我国目前将下列8种常见且危害性大的性传播疾病列为重点防治的疾病：梅毒、淋病、非淋菌性尿道炎、生殖器疱疹、尖锐湿疣、软下疳、性病性淋巴肉芽肿和艾滋 病。

A sexually transmitted disease (STD), also known as sexually transmitted infection (STI) or venereal disease (VD), is an illness that has a significant probability of transmission between humans or animals by means of human sexual behavior, including vaginal intercourse, oral sex, and anal sex. While in the past, these illnesses have mostly been referred to as STDs or VD, in recent years the term sexually transmitted infection (STI) has been preferred, as it has a broader range of meaning; a person may be infected, and may potentially infect others, without showing signs of disease. Some STIs can also be transmitted via the use of IV drug needles after its use by an infected person, as well as through childbirth or breastfeeding. Sexually transmitted infections have been well known for hundreds of years.

Classification and terminology

Until the 1990s, STDs were commonly known as venereal diseases : Veneris is the Latin genitive form of the name Venus, the Roman goddess of love. Social disease was another euphemism.

Public health officials originally introduced the term sexually transmitted infection, which clinicians are increasingly using alongside the term sexually transmitted disease in order to distinguish it from the former. According to the Ethiopian Aids Resource Center FAQ, "Sometimes the terms STI and STD are used interchangeably. This can be confusing and not always accurate, so it helps first to understand the difference between infection and disease. Infection simply means that a germ—virus, bacteria, or parasite—that can cause disease or sickness is present inside a person’s body. An infected person does not necessarily have any symptoms or signs that the virus or bacteria is actually hurting his or her body; they do not necessarily feel sick. A disease means that the infection is actually causing the infected person to feel sick, or to notice something is wrong. For this reason, the term STI—which refers to infection with any germ that can cause an STD, even if the infected person has no symptoms—is a much broader term than STD."^[1] The distinction being made, however, is closer to that between a colonization and an infection, rather than between an infection and a disease.

Specifically, the term STD refers only to infections that are causing symptoms. Because most of the time people do not know that they are infected with an STD until they start showing symptoms of disease, most people use the term STD, even though the term STI is also appropriate in many cases.

Moreover, the term sexually transmissible disease is sometimes used since it is less restrictive in consideration of other factors or means of transmission. For instance, meningitis is transmissible by means of sexual contact but is not labeled as an STI because sexual contact is not the primary vector for the pathogens that cause meningitis. This discrepancy is addressed by the probability of infection by means other than sexual contact. In general, an STI is an infection that has a negligible probability of transmission by means other than sexual contact, but has a realistic means of transmission by sexual contact (more sophisticated means—blood transfusion, sharing of hypodermic needles—are not taken into account). Thus, one may presume that, if a person is infected with an STI, e.g., chlamydia, gonorrhea, genital herpes, it was transmitted to him/her by means of sexual contact.

The diseases on this list are most commonly transmitted solely by sexual activity. Many infectious diseases, including the common cold, influenza, pneumonia, and most others that are transmitted person-to-person can also be transmitted during sexual contact, if one person is infected, due to the close contact involved. However, even though these diseases may be transmitted during sex, they are not considered STDs.

那上公厕会不会正好倒霉，水流到公共马桶上，传染给别人。

公司我还是要垫纸，不过还是不放心，其实垫纸也是做做样子，很多时候纸都歪到一边去了。悬空对我来说难度太大，而且好多人悬空以后都弄到马桶盖上或者地上了
