艾滋发作的典型症状

    2010-03-18 08:19:50
  艾滋病发作的时候到底会有什么样的表现?
  现在许多人一谈到艾滋病就有点”谈艾色变”, 特别是曾直接或间接有过不洁性接触的人, 一遇到身体有什么不适或心情不好时, 就会往艾滋病上想, 非要跑到医院去反复检查艾滋病毒抗体, 一个医院查了不算, 要到几个医院, 一次不行, 还要多次, 查了阴性, 仍不相信, 需要反复的解释才稍安静一些, 总把这些症状与艾滋病联系在一起, 既怀疑有,又希望医生能否定它。 这是典型的艾滋病恐惧心理。

  其实, 艾滋病的发作表现的症状并无特异性。 因为艾滋病毒侵犯的是人体的防御细胞, 它把人体的免疫功能给摧垮了,就像一个国家的军队被消灭了一样, 引起整个国家发生内乱, 其表现的形式是多种多样, 艾滋病发作时最多的是易感冒, 生出莫名其妙的肺炎, 并容易伴发细菌,真菌或病毒感染, 用常规的药常不容易获得好的效果, 或刚治好,又冒出过新的感染。 多数会进一步加重, 多死于继发的疱疹病毒感染或念珠菌感染等。

  有些人会出现不明原因发生腹泻, 不容易止住。 因病人的免疫力低, 免疫功能紊乱, 还易过敏, 如得寻麻疹,皮炎等。

  我们在临床上所看到的艾滋病发作表现都不一样, 有一位妇女几个月不明原因的全身瘙痒, 多方检查治疗无效, 因她曾输过血, 后一查艾滋病毒抗体阳性, 才知道艾滋病发作了,且是以恶痒的形式表现出来的。

  皮肤上表现为大小不等的水疱, 形似播散性带状疱疹的特征, 并比后者要严重得多, 这也是一些艾滋病人发作的一个较有特征的皮肤改变, 我们曾见到一位23岁的小伙子发生这样的情况, 不久就死亡了。

  另外有些人手指甲突然变颜色,整个指趾甲很快变成灰色,增厚,又无法用常规的营养不良等原因所解释。还有些人不明原因在身上出皮疹,范围越来越大,用药疹等都不好解释,要警惕是否有艾滋病的可能。

  在四肢出现暗红色的结节, 特别是在手足背的位置发生, 可单个的或融合成多个的, 有疼痛等, 过去我们叫它卡波氏肉瘤, 是皮肤血管发生的一种较罕见的血管恶性肿瘤, 现在认为是艾滋病的一个较有特异性的表现。 有些以淋巴瘤表现为主。

  艾滋病毒还可侵犯脑干神经和周围神经,引起病人痴呆,生活自理能力丧失,或出现明显的消瘦,足部麻木,偏瘫等。

  有些人在患有其他性病治疗时, 无意中发现。 如有位年轻的女性检查有尖锐湿疣, 经多次治疗未见好转, 反而越治疣体越长越大, 这也是不好的前兆, 一查艾滋病抗体阳性。

  总之,艾滋病的发作表现是五花八门。 而感染上艾滋病毒到发作却要经过比较慢长的时间, 因人因情况不一样, 短则几个月, 长则10余年,潜伏期在2-15年不等, 平均在8-10年。 一般通过吸毒或血液途径传播感染的要在5-9年发病,而通过性接触的时间要长一些。 没发病的,在感染期就像带肝炎病毒感染一样,和正常人没什么不同, 不要有什么恐惧的心理, 要保持良好的心态, 避免劳累和感冒, 不要情绪低落, 积极阳光的生活, 定期检查看病毒指数是否达到要给予干预药治疗的情况, 这样, 发病的时间会明显向后推迟。社会各个阶层都要关心和爱护他们, 要保护好他们的隐私, 不要歧视他们, 其实正常的接触是没有传染性的。

  那些更多的有不良性接触的人, 不要把自己置身于艾滋病的恐怖中, 还自己良好的生活和心情状态, 洁身自好, 既然在医院检查艾滋病毒抗体是阴性了, 就没必要老怀疑自己有这种可能, 人身上的许多不适,有些是心情不好引起的, 有些是其它的问题, 上医院看看就行, 不要疑神疑鬼, 让自己和家人活在艾滋病的困扰中。

艾滋發作的典型症狀

    
2010-03-18 08:19:50
艾滋病發作的時候到底會有什麼樣的表現?
現在許多人一談到艾滋病就有點”談艾色變”, 特別是曾直接或間接有過不潔性接觸的人, 一遇到身體有什麼不適或心情不好時, 就會往艾滋病上想, 非要跑到醫院去反複檢查艾滋病毒抗體, 一個醫院查了不算, 要到幾個醫院, 一次不行, 還要多次, 查了陰性, 仍不相信, 需要反复的解釋才稍安靜一些, 總把這些症狀與艾滋病聯繫在一起, 既懷疑有,又希望醫生能否定它。這是典型的艾滋病恐懼心理。

其實, 艾滋病的發作表現的症狀並無特異性。因為艾滋病毒侵犯的是人體的防禦細胞, 它把人體的免疫功能給摧垮了,就像一個國家的軍隊被消滅了一樣, 引起整個國家發生內亂, 其表現的形式是多種多樣, 艾滋病發作時最多的是易感冒, 生出莫名其妙的肺炎, 並容易伴發細菌,真菌或病毒感染, 用常規的藥常不容易獲得好的效果, 或剛治好,又冒出過新的感染。多數會進一步加重, 多死於繼發的皰疹病毒感染或念珠菌感染等。

有些人會出現不明原因發生腹瀉, 不容易止住。因病人的免疫力低, 免疫功能紊亂, 還易過敏, 如得尋麻疹,皮炎等。

我們在臨床上所看到的艾滋病發作表現都不一樣, 有一位婦女幾個月不明原因的全身瘙癢, 多方檢查治療無效, 因她曾輸過血, 後一查艾滋病毒抗體陽性, 才知道艾滋病發作了,且是以惡癢的形式表現出來的。

皮膚上表現為大小不等的水皰, 形似播散性帶狀皰疹的特徵, 並比後者要嚴重得多, 這也是一些艾滋病人發作的一個較有特徵的皮膚改變, 我們曾見到一位23歲的小伙子發生這樣的情況, 不久就死亡了。

另外有些人手指甲突然變顏色,整個指趾甲很快變成灰色,增厚,又無法用常規的營養不良等原因所解釋。還有些人不明原因在身上出皮疹,範圍越來越大,用藥疹等都不好解釋,要警惕是否有艾滋病的可能。

在四肢出現暗紅色的結節, 特別是在手足背的位置發生, 可單個的或融合成多個的, 有疼痛等, 過去我們叫它卡波氏肉瘤, 是皮膚血管發生的一種較罕見的血管惡性腫瘤, 現在認為是艾滋病的一個較有特異性的表現。有些以淋巴瘤表現為主。

艾滋病毒還可侵犯腦幹神經和周圍神經,引起病人癡呆,生活自理能力喪失,或出現明顯的消瘦,足部麻木,偏癱等。

有些人在患有其他性病治療時, 無意中發現。如有位年輕的女性檢查有尖銳濕疣, 經多次治療未見好轉, 反而越治疣體越長越大, 這也是不好的前兆, 一查艾滋病抗體陽性。

總之,艾滋病的發作表現是五花八門。而感染上艾滋病毒到發作卻要經過比較慢長的時間, 因人因情況不一樣, 短則幾個月, 長則10餘年,潛伏期在2-15年不等, 平均在8-10年。一般通過吸毒或血液途徑傳播感染的要在5-9年發病,而通過性接觸的時間要長一些。沒發病的,在感染期就像帶肝炎病毒感染一樣,和正常人沒什麼不同, 不要有什麼恐懼的心理, 要保持良好的心態, 避免勞累和感冒, 不要情緒低落, 積極陽光的生活, 定期檢查看病毒指數是否達到要給予干預藥治療的情況, 這樣, 發病的時間會明顯向後推遲。社會各個階層都要關心和愛護他們, 要保護好他們的隱私, 不要歧視他們, 其實正常的接觸是沒有傳染性的。

那些更多的有不良性接觸的人, 不要把自己置身於艾滋病的恐怖中, 還自己良好的生活和心情狀態, 潔身自好, 既然在醫院檢查艾滋病毒抗體是陰性了, 就沒必要老懷疑自己有這種可能, 人身上的許多不適,有些是心情不好引起的, 有些是其它的問題, 上醫院看看就行, 不要疑神疑鬼, 讓自己和家人活在艾滋病的困擾中。

HIV attacks the typical symptoms of

    
2010-03-18 08:19:50
The onset of AIDS, when in the end what kind of performance?
Many people nowadays mention of AIDS in a bit, "Tan Ai pale", especially those who directly or indirectly, had unclean sexual contact person, an experienced body have any discomfort or a bad mood, they will go to AIDS may want to that must go to the hospital to repeatedly check the HIV antibody, a hospital checked not want to go to several hospitals, one not, but also several times, checked the negative, still not convinced of the need repeated explanation, despite a slight Quiet The total of these symptoms of AIDS linked to both suspected to have, but also hope that doctors will be able to deny it. This is typical of AIDS fear.

In fact, the AIDS onset of presenting symptoms is not specific. Because HIV violation of the body's defense cells, it is the body's immune function to the crushed, just as a country's army was wiped out, like, causing the country to civil disturbances, its performance in the form of a variety of forms, the onset of AIDS When most are easy flu, birth unexplained pneumonia, and easily associated with bacterial, fungal or viral infections, conventional medicine often is not easy to obtain good results, or just heal, but also cropped up any new infections. Most of this will further add, multi-die secondary to herpes simplex virus infection or Candida infection.

Some people will appear unexplained diarrhea, is not easy to halt. Of patients with low immunity, immune disorders, but also easy to allergies, where a look for measles, dermatitis and so on.

Our clinical see the onset of AIDS did not perform the same, there is a woman a few months of unknown causes systemic itching, multi-party examination and treatment is invalid, because she had blood transfusion after an investigation of HIV-positive, before we know AIDS onset of, and is a bad itch in the form shown.

The skin showed the size ranging from blisters, the shape of disseminated herpes zoster of the characteristics and than the latter to be much more serious, which is why some people with AIDS onset of a more characteristic skin changes, we have seen a 23-year-old young man happen, and soon died.

Other people fingernails suddenly changed color, the mean toenail quickly turned into a gray, thick, and could not use conventional malnutrition and other reasons explain this. Still others of unknown causes on the body out of rash, the scope of the growing use of drug eruption and so well explained that we must be vigilant if there AIDS possible.

In the limbs dark red nodules, especially in the hand, foot and back the location of occurrence may be single or integration into multiple, there are pain in the past we call Kaposi's sarcoma, the skin blood vessels occurred in a relatively uncommon vascular tumor, is now considered to be AIDS, a more specific performance. Some with lymphoma that focus.

HIV can also be violations of brainstem and peripheral nerves, causing patients with dementia, activities of daily living lost, or noticeable weight loss, foot numbness, paralysis, etc..

Some people who suffer from other sexually transmitted diseases treatment, accidentally discovered. If a young female check genital warts and after repeated treatment did not improve, the worse the government wart longer large, this is a bad harbinger of an investigation of AIDS antibodies.

In short, AIDS onset of performance was varied. Infected with HIV to the onset of have to been relatively slow long time, because people were not the same as short then a few months or as long as more than 10 years, the incubation period in the 2-15 years, and an average of 8-10 years. Generally through drug use or blood-transmitted infections in 5-9 years the disease, but through sexual contact time should be longer. No disease, the infection period is like with a hepatitis virus infection in the same, and the normal people are no different, do not have any fear, psychological, to maintain a good attitude, avoid fatigue and cold, not depression, positive sunny side of life, regular checks to see the virus index of whether the should be given intervention in drug therapy that case, the onset of time will be significantly deferred. All levels of society should care for and love them, to protect their privacy, do not discriminate against them, in fact, the normal contacts are not infectious.

Those more adverse sexual contact person, do not put themselves in AIDS, terrorism, it is also their good living and mood state, keeping oneself clean, since in the hospital for an examination of HIV antibody was negative, and no need for the old suspicion that they have this possibility, the human body a lot of discomfort, some are in a bad mood cause, and some other problems, go to the hospital to see on the line, not paranoid, let himself and his family live in the AIDS troubling.

AIDS in the performance of the different disease

    
2010-03-18 08:19:43
Onset of AIDS in the most common cold is easy when cold, give birth unexplained pneumonia, and easily associated with bacterial, fungal or viral infections, conventional medicine often is not easy to obtain good results, or just heal, but also over new infections emerge . Most will be further accentuated.
Some people diarrhea of unknown causes diarrhea, is not easy to halt.

Allergic patients with low immunity due to immune dysfunction, but also easy to allergies, such as too urticaria, dermatitis and so on.

Skin itching a woman's body a few months of unknown causes itching, multi-party examination and treatment ineffective, as she had blood transfusion after an investigation of HIV-positive, before we know the onset of AIDS, and evil is manifested in the form of itching .

Manifested as blisters on the skin blisters of varying sizes, the shape of the characteristics of disseminated herpes zoster, and far more serious than the latter, which is why some people with AIDS onset of a more characteristic skin changes, we have seen a bit, 23-year-old young man happen, and soon died.

Means (toe) A change in color of some people fingernails suddenly, the whole nail that quickly turned into a gray, thick, and could not use conventional malnutrition and other reasons explain this.

Rash also some unexplained rash on his body out of scope of the growing use of drug eruption and so well explained, we must guard against the possibility of whether there is AIDS.

Nodules on the limbs appeared dark red nodules, especially in the hand, foot and back the location of occurrence may be single or integration into multiple, there are pain in the past we call Kaposi's sarcoma, a skin angiogenesis relatively rare vascular malignancy, AIDS is now considered to be a more specific performance.

Some people who suffer from other sexually transmitted diseases treatment, accidentally discovered. If a young female check genital warts and after repeated treatment did not improve, the worse the longer rule wart big, which is not good precursor, a check of AIDS antibodies.

Infected with HIV to have to attack more slowly over a long time, because people were not the same case, the short is a few months or as long as more than 10 years, the average incubation period of 8-10 years.

关于艾滋病的几个常识

 
 
 
 
 

关于艾滋病的几个常识

    2010-03-18 08:19:54
  携带艾滋病病毒就意味着患有艾滋病吗?
  艾滋病(获得性免疫缺损综合症)是世界上迄今所知最严重的流行病之一。艾滋病病毒(人体免疫缺损病毒)是引起艾滋病的病毒。艾滋病病毒最早发现于 1981的中非边远地区,然后就席卷全球,在相对较短的时间内感染了数百万人。

  艾滋病病毒像所有病毒一样是存活与无法存活的分界线。病毒缺少人类细胞用来支持生命的化学系统。所以,艾滋病病毒需要宿主细胞以保持生命并复制。为了复制,病毒在宿主细胞内创造新的病毒粒子,这些粒子把病毒带到新的细胞中。

  艾滋病病毒感染一种独特类型的免疫系统细胞。该细胞称为CD4+T细胞,也叫做T辅助细胞(有关 T 细胞的详细信息,请参见免疫系统工作原理)。艾滋病病毒一旦进入身体,就朝淋巴组织运动,以便在淋巴组织中找到T 辅助细胞。T 辅助细胞一旦受感染就转变成艾滋病病毒复制细胞。在健康人体内,通常每1 毫升血液中含有1百万个T细胞。

  新复制的病毒粒子感染其他T辅助细胞,导致人的 T 辅助细胞计数慢慢减少。T 辅助细胞在身体的免疫反应中起重要作用,所以T辅助细胞的缺乏会危害免疫系统。当一个人的T 辅助细胞计数减少到每1毫升血液20万个细胞以下时,这个人就被认为患了艾滋病。据疾病控制中心 (CDC) 所说,艾滋病的患病要花大约2到15年,但携带艾滋病病毒的所有人中约有半数将在感染后的10年内患上艾滋病。

  没有人明确地说是死于艾滋病或艾滋病病毒。感染艾滋病的人死于感染,因为其免疫系统被削弱。艾滋病病人会像死于癌症一样容易地死于感冒。患者不能战胜感染,最终会死于一些疾病,而这些疾病对于非艾滋病病毒感染者来说是能够快速康复的。

  避孕套有防艾滋的效果吗?

  在很多“艾滋病预防措施”中,都有这样一条:“提倡使用避孕套”。使用避孕套真的可以避免感染艾滋病毒吗?

  或者我们可以换个问法:如果你有机会跟梦寐以求的对象发生性关系,但他/她感染了艾滋病毒,你是否愿意和他/她凭借避孕套的保护做爱?

  众多避孕套推广者的答案是:不愿意。

  顾名思义,避孕套的初衷只是为了避免性行为过程中双方体液和生殖细胞的交流,从而大大降低女方的意外受孕几率。但需知,即使是这个最本质的目的,也存在2%以上的失败几率。

  更何况,艾滋病毒的体积足足比精子体积小了2000倍。即使在整个过程中,避孕套保持完整,艾滋病毒仍有可能经由避孕套上不易觉察的微小缝隙,进入对方体内,并通过轻微擦伤造成的伤口,进入血液,导致对方的感染。

  和意外受孕相比,艾滋病毒的危险性复杂得多。除了事件发生的外部环境,更体现在艾滋病毒感染过程的本身。

  比如:女性每月只有一次排卵,因此只有发生在排卵期的性行为才会导致怀孕,而艾滋病毒感染人体细胞却不受日程限制;精子与卵子结合的通道只有一条,艾滋病毒却可以通过皮肤或黏膜上任何的伤口进入人体;怀孕只会发生在女性的一方,而感染艾滋病毒的风险却是男女不限(不公平的是,出于生殖器官结构的原因,女性感染艾滋病毒的机会是男性的3倍以上),等等。

  可见,不论是从接触部位还是时机看,使用避孕套的过程中,感染艾滋病都比意外怀孕的几率高出许多(当然前提是其中一方是艾滋病人或艾滋病毒携带者)。因此,在艾滋病的预防方面,使用避孕套只能是聊胜于无,但绝非安全百分百。而最关键的是,一旦意外发生,怀孕可以通过人工方式补救,艾滋病毒的感染却无法挽回。

  为什么男同性恋性行为更容易传播艾滋病?

  男性同性恋艾滋病感染率在中国艾滋病高危人群中居第二位,仅此于吸毒。为什么偏偏是男性同性恋呢?

  首先,男同性恋大多没有固定的性伴侣。“拥有多名性伴侣”往往是感染艾滋病或其他性病的主要原因。

  其次,男性同性性行为通常采取口交或肛交的方式,尤其是后者,大大加剧了男性同性恋感染艾滋病的风险。直肠内的碱性环境很适宜于病毒的生存繁殖,而且肛肠的黏膜薄而娇嫩,其下有丰富的毛细血管,发生性行为时极易引起破损出血,使病原体从肛门或直肠的破损处侵入,直接进入血液。

  而且,男性同性恋往往存在避孕套使用率低的现象,并且相当一部分都和异性组建了家庭或同时拥有异性的性伴侣,这无疑更加剧了艾滋病由高危人群向普通人群扩散的危险性。

  我会因蚊子叮咬感染艾滋病吗?

  有关艾滋病病毒传播最普遍的荒诞说法之一就是,蚊子或其他吸血昆虫会使您受感染。没有科学证据可以支持这一论点。为了解为什么蚊子对于艾滋病病毒的传播没有帮助,我们可以研究一下蚊子的叮咬行为。

  当蚊子叮咬某人时,不会把自己的血液或者它所叮咬的动物或人的血液注入到它叮咬的下一个人体内。蚊子会喷射唾液,唾液充当润滑剂,以便它能有效地吸取更多血液。黄热病和疟疾会通过唾液传播,但艾滋病病毒不能在昆虫体内复制,所以病毒不能在蚊子体内存活足够长的时间以通过唾液传播。

  此外,蚊子吸血之后通常不会从一个人身上飞到另一个人身上。它们需要时间来消化“血餐”,然后才会继续觅食。

關於艾滋病的幾個常識

    
2010-03-18 08:19:54
攜帶艾滋病病毒就意味著患有艾滋病嗎?
艾滋病(獲得性免疫缺損綜合症)是世界上迄今所知最嚴重的流行病之一。艾滋病病毒(人體免疫缺損病毒)是引起艾滋病的病毒。艾滋病病毒最早發現於1981的中非邊遠地區,然後就席捲全球,在相對較短的時間內感染了數百萬人。

艾滋病病毒像所有病毒一樣是存活與無法存活的分界線。病毒缺少人類細胞用來支持生命的化學系統。所以,艾滋病病毒需要宿主細胞以保持生命並複制。為了複製,病毒在宿主細胞內創造新的病毒粒子,這些粒子把病毒帶到新的細胞中。

艾滋病病毒感染一種獨特類型的免疫系統細胞。該細胞稱為CD4+T細胞,也叫做T輔助細胞(有關T 細胞的詳細信息,請參見免疫系統工作原理)。艾滋病病毒一旦進入身體,就朝淋巴組織運動,以便在淋巴組織中找到T 輔助細胞。 T 輔助細胞一旦受感染就轉變成艾滋病病毒複製細胞。在健康人體內,通常每1 毫升血液中含有1百萬個T細胞。

新復制的病毒粒子感染其他T輔助細胞,導致人的T 輔助細胞計數慢慢減少。 T 輔助細胞在身體的免疫反應中起重要作用,所以T輔助細胞的缺乏會危害免疫系統。當一個人的T 輔助細胞計數減少到每1毫升血液20萬個細胞以下時,這個人就被認為患了艾滋病。據疾病控制中心(CDC) 所說,艾滋病的患病要花大約2到15年,但攜帶艾滋病病毒的所有人中約有半數將在感染後的10年內患上艾滋病。

沒有人明確地說是死於艾滋病或艾滋病病毒。感染艾滋病的人死於感染,因為其免疫系統被削弱。艾滋病病人會像死於癌症一樣容易地死於感冒。患者不能戰勝感染,最終會死於一些疾病,而這些疾病對於非艾滋病病毒感染者來說是能夠快速康復的。

  避孕套有防艾滋的效果嗎?

在很多“艾滋病預防措施”中,都有這樣一條:“提倡使用避孕套”。使用避孕套真的可以避免感染艾滋病毒嗎?

或者我們可以換個問法:如果你有機會跟夢寐以求的對象發生性關係,但他/她感染了艾滋病毒,你是否願意和他/她憑藉避孕套的保護做愛?

眾多避孕套推廣者的答案是:不願意。

顧名思義,避孕套的初衷只是為了避免性行為過程中雙方體液和生殖細胞的交流,從而大大降低女方的意外受孕機率。但需知,即使是這個最本質的目的,也存在2%以上的失敗機率。

更何況,艾滋病毒的體積足足比精子體積小了2000倍。即使在整個過程中,避孕套保持完整,艾滋病毒仍有可能經由避孕套上不易覺察的微小縫隙,進入對方體內,並通過輕微擦傷造成的傷口,進入血液,導致對方的感染。

和意外受孕相比,艾滋病毒的危險性複雜得多。除了事件發生的外部環境,更體現在艾滋病毒感染過程的本身。

比如:女性每月只有一次排卵,因此只有發生在排卵期的性行為才會導致懷孕,而艾滋病毒感染人體細胞卻不受日程限制;精子與卵子結合的通道只有一條,艾滋病毒卻可以通過皮膚或黏膜上任何的傷口進入人體;懷孕只會發生在女性的一方,而感染艾滋病毒的風險卻是男女不限(不公平的是,出於生殖器官結構的原因,女性感染艾滋病毒的機會是男性的3倍以上),等等。

可見,不論是從接觸部位還是時機看,使用避孕套的過程中,感染艾滋病都比意外懷孕的機率高出許多(當然前提是其中一方是艾滋病人或艾滋病毒攜帶者)。因此,在艾滋病的預防方面,使用避孕套只能是聊勝於無,但絕非安全百分百。而最關鍵的是,一旦意外發生,懷孕可以通過人工方式補救,艾滋病毒的感染卻無法挽回。

為什麼男同性戀性行為更容易傳播艾滋病?

男性同性戀艾滋病感染率在中國艾滋病高危人群中居第二位,僅此於吸毒。為什麼偏偏是男性同性戀呢?

首先,男同性戀大多沒有固定的性伴侶。 “擁有多名性伴侶”往往是感染艾滋病或其他性病的主要原因。

其次,男性同性性行為通常採取口交或肛交的方式,尤其是後者,大大加劇了男性同性戀感染艾滋病的風險。直腸內的鹼性環境很適宜於病毒的生存繁殖,而且肛腸的黏膜薄而嬌嫩,其下有豐富的毛細血管,發生性行為時極易引起破損出血,使病原體從肛門或直腸的破損處侵入,直接進入血液。

而且,男性同性戀往往存在避孕套使用率低的現象,並且相當一部分都和異性組建了家庭或同時擁有異性的性伴侶,這無疑更加劇了艾滋病由高危人群向普通人群擴散的危險性。

  我會因蚊子叮咬感染艾滋病嗎?

有關艾滋病病毒傳播最普遍的荒誕說法之一就是,蚊子或其他吸血昆蟲會使您受感染。沒有科學證據可以支持這一論點。為了解為什麼蚊子對於艾滋病病毒的傳播沒有幫助,我們可以研究一下蚊子的叮咬行為。

當蚊子叮咬某人時,不會把自己的血液或者它所叮咬的動物或人的血液注入到它叮咬的下一個人體內。蚊子會噴射唾液,唾液充當潤滑劑,以便它能有效地吸取更多血液。黃熱病和瘧疾會通過唾液傳播,但艾滋病病毒不能在昆蟲體內復制,所以病毒不能在蚊子體內存活足夠長的時間以通過唾液傳播。

此外,蚊子吸血之後通常不會從一個人身上飛到另一個人身上。它們需要時間來消化“血餐”,然後才會繼續覓食。

Some knowledge about AIDS

Living with HIV means that people with AIDS?
AIDS (acquired immune deficiency syndrome) is the world has ever known, one of the most serious epidemics. HIV (Human Immunodeficiency Virus) is the virus that causes AIDS. AIDS virus first found in 1981 in remote areas of Central Africa, and then swept the globe, in a relatively short period of time, infected millions of people.

Like all viruses, HIV is the dividing line between survival and not survive. Viruses lack of human cells to support the life-chemical systems. Therefore, the AIDS virus needs to maintain the life of the host cell and replicate. In order to reproduce, the virus in host cells to create new virus particles, these particles the virus into new cells.

HIV infection of a unique type of immune system cells. The cell known as CD4 + T cells, also known as T helper cells (the T cells, more information, please see the immune system works). Once HIV enters the body on the movement toward lymphoid tissues, lymphoid tissues in order to find the T helper cells. T helper cells, once infected the cells into HIV replication. In the healthy human body, usually every 1 ml of blood containing one million T cells.

The new copy of virus particles infect other T helper cells, resulting in human T-helper cell count is diminishing. T helper cells of the body's immune response play an important role, so the lack of T helper cells would endanger the immune system. When a person's T-helper cell count per 1 ml of blood is reduced to 200,000 cells below, that person is considered suffering from AIDS. According to Centers for Disease Control (CDC) said the prevalence of AIDS takes about 2 to 15 years, but all those living with HIV, about half of the 10 years after infection and suffering from AIDS.

No one explicitly said to have died of AIDS or HIV. HIV-infected people die from infection, because its immune system is weakened. AIDS patients will die of cancer, as cold as easily die. Patient can not overcome infection will eventually die of some diseases, these diseases for non-HIV-infected persons is fast recovery.

Condoms prevent HIV's effect?

In many "AIDS Prevention Initiatives", have such a: "to promote the use of condoms." The use of condoms to avoid HIV infection really do?

Or we can change the question is asked: If you have a chance with the dream object of sexual relations, but he / she was infected with the HIV virus, are you willing and his / her protected sex with condoms?

Large number of condom promoters answer is: do not want.

As the name suggests, the original intention of condoms during sex only to avoid the two sides exchange of body fluids and reproductive cells, and thus greatly reduce the chances of the woman's unwanted pregnancy. However, should know that even this most fundamental purpose, there are more than 2% chance of failure.

Moreover, the volume of HIV than the sperm of a full size smaller 2000-fold. Even in the whole process, the integrity of condoms, HIV is still possible through a condom on a tiny imperceptible cracks to enter each other's body, and through minor abrasions caused by wounds, into the blood, leading to other infections.

And unwanted pregnancy compared with the risk of HIV is much more complicated. In addition to the events of the external environment, even more apparent in the course of HIV infection itself.

For example: Women ovulate only once a month, only occurred in the ovulation period, sexual activity would lead to pregnancy, but HIV-infected human cells is not subject to scheduling constraints; sperm and the egg is only one channel, HIV could be alleviated through the skin any wounds or mucous membranes to enter the human body; pregnancy only occurred in the women's side, while the risk of HIV infection is not limited to men and women (not fair that, for the reasons for genital structures, women infected with HIV opportunities 3 times more than men), and so on.

See, whether it is time to look at from the contact area or the use of condoms in the process of HIV infection than the risk of unwanted pregnancies is much higher (of course, one of which is the premise that people with AIDS or HIV). Thus, in AIDS prevention, the use of condoms can only be better than nothing, but not hundred percent safe. The most critical is that once the accident, pregnancy through artificial remedies, HIV infection is irreversible.

Why is gay sex more easily spread of AIDS?

Male homosexual AIDS infection in high-risk groups of AIDS in China, ranked second, only the drug-taking. Then why do gay men?

First of all, most gay men there is no fixed sexual partner. "Having multiple sex partners" are often infected with AIDS or other sexually transmitted diseases, the main reason.

Second, the male homosexual sex is usually the way to oral sex or anal sex, especially the latter, greatly exacerbated the risk of HIV infection in homosexual men. Alkaline environment inside the rectum is very suitable for survival of the virus reproduction, and the anorectal mucosa thin and delicate, under which is rich in capillaries, have sex when you can easily damage caused by bleeding, so that pathogens from the anus or rectum of the breakage penetrated directly into the bloodstream.

Moreover, the existence of male homosexuality is often the phenomenon of low condom usage, and a considerable portion of the opposite sex have both set up a home or the opposite sex sexual partners, no doubt exacerbated by the AIDS high-risk groups to the general population from the danger of the spread.

I suffer from mosquito bites and infected with HIV do?

AIDS-related transmission of the virus, one of the most common myth is that, mosquitoes or other blood-sucking insects will make you infected. There is no scientific evidence to support this argument. In order to understand why the mosquitoes for the spread of HIV does not help, we can look at behavior of mosquito bites.

When the mosquito bites a person, it will not put their own blood, or it bites an animal or person's blood injected into the body the next person it bites. Will spray mosquito saliva, saliva acts as lubricant, so that it can effectively absorb more blood. Yellow fever and malaria spread through saliva, but HIV can not be insect reproduction, so the virus can not survive long enough in the mosquito body time to spread through saliva.

In addition, blood-sucking mosquitoes, after usually do not fly from one person to another person. They need time to digest "blood meal", and then will continue to have food.
