If HIV virus won't live more than 1min the how come vaginal fluid having HIV on cloth exposed outside wiped at tip of penis can cause HIV infection?

Wrong assumption!: HIV virus can survive for weeks, outside the body, depending on the composition of the fluid containing the virus and ambient temperature. The infectivity depends on contact with skin that may have abrasions, open sore or other wounds.

Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

Explan why one human immunodeficiency virus test cannot definitely diagnose hiv?

Explan why one human immunodeficiency virus test cannot definitely diagnose hiv?

Good question: The HIV test to which you refer is an elisa assay which is quite sensitive but not as specific as the confirmatory western blot. These measure the presence of antibodies to the HIV and these may take from 2 wks to several months to develop. If you run the test before the antibodies have appeared, it will be negative, only to change to positive once antibody formation has occurred. ...Read more

Is there more than one strain of virus that can cause hiv?

Yes: There are two types of hiv-hiv 1 and hiv2.Both are transmitted thru sexual contact, thru blood , and from mother to child and they appear to cause clinically indistinguishable aids.However, hiv2 is less easily transmitted & period bet.Initial infection/illness is longer w hiv2(concentrated in w.Africa, rarely fd elsewhere).Worldwide, predominant virus is hiv-1 w subgroups m, n, o & p. ...Read more

Is there more than one mumps virus strain going around?

Is there more than one mumps virus strain going around?

Only one mumps: Parotitis , the single or doublesided swelling of the parotid gland is the classical feature of mumps. There is one mumps virus. However, there are multiple other viruses and some bacteria that can cause infection/swelling in the parotid glands. Just having swollen parotid glands does not mean you have mumps. ...Read more

Hi,I would like to know does ureaplasma parvum/ureaplasma ureaticum.causes complications.What viruses linked to hiv or aids.

Ureaplasma: Chronic infection with this organism can produce changes in the urethra, just as with any other form of inflammation. The only virus linked to HIV/AIDS is HIV (Human Immunodeficiency Virus). Many viruses may attack a compromised immune system in a patient with this illness. ...Read more

Why are gays more prone to HIV then straight people. Straight people have unprotected vaginal penal sex all the time n don't contract the virus.

Why are gays more prone to HIV then straight people. Straight people have unprotected vaginal penal sex all the time n don't contract the virus.

It's all dangerous: Dr. Graham is correct about anal sex being more likely to produce trauma, whether the passive partner is male or female. In Africa, HIV is transmitted primarily by heterosexual intercourse. Exactly why this happens is one of medicine's major mysteries. If you find romance, please love safely, regardless of who or how, and thanks for your question. ...Read more

More detail to my question about having sex with a woman that is HIV positive? My question is if I have sex with a woman that is said to be HIV positive, does that mean that i will contact the virus too?

More detail to my question about having sex with a woman  that is HIV positive? My question is if I have sex with a woman that is said to be HIV positive, does that mean that i will contact the virus too?

Many : Many issues come into play when were discussing HIV transmission. First and foremost...Was the sex protected (ie condom use). Using a condom lowers the risk of transmission virtually entirely. If there was kissing and oral sex involved..Was there exchange of fluids? The type of fluid matters greatly. If its simply saliva the risk is very very low. There is virus present in the saliva of HIV positively infected people but it is not to the level thought to cause infection. If there were open lesions or bleeding gums for example...The risk goes up. Another think to consider is was the HIV positive person on anti-retrovirals (meds for the hiv). If the person is undetectable (meaning the virus count found in the blood is almost nonexistant) then the rate of possible transmission goes down by 96%. Keep in mind these are only general guidlines. Its a complicated virus and disease that it causes. ...Read more

Dose having sex with my wife, my g.Friend cause hiv. V all, me, my wife, my g.Friend n her husband are HIV negative n r not affected with any virus?

HIV cannot be caused: Hiv is a virus and cannot be "caused". It has to be passed from one person to another, most often by direct contact between people (such as during sex). If none of the sex partners have hiv, then HIV cannot be "caused" by having sex among those partners. However, how does a person truly know for sure none of the partners have hiv, or one of many other contagious diseases transmissible sexually? ...Read more

Why aren't HIV and AIDS just one name if they are both the same virus?

Why aren't HIV and AIDS just one name if they are both the same virus?

HIV is the virus: HIV (human immunodeficiency virus) is the name of the virus, whereas AIDS (Acquired Immune Deficiency Syndrome) refers to someone who has HIV, but whose immune system has been greatly affected such that they have had one of the many AIDS defining illnesses/infections or their CD4 cell count (a measure of one's immune system) drops below 200. Thus, a person can have HIV, but not qualify for AIDS. ...Read more
