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

Is HIV infectious if it is outside the body?

Is HIV infectious if it is outside the body?

Generally not: If the virus remains in human materials like blood, semen, or other body secretions that are not subjected to physical changes which kill the virus it can survive, but outside of these it dies very rapidly upon removal from the body. That is why it takes intimate contact for transmission and does not occur casually. ...Read more

How long can HIV survive and remain infectious on things like door handles and other everyday objects?

How long can HIV survive and remain infectious on things like door handles and other everyday objects?

Not long: HIV is not acquired through casual contact. It is acquired through body fluids such as blood, urine, breast milk and semen. Anyone who is worried about their risk for HIV should stop risky sex and drug abuse and get tested. ...Read more

How long could HIV semen still be infectious outside the body?

How long could HIV semen still be infectious outside the body?

Don't take chances: While HIV is reported as only capable of living hours-days in the environment, some hepatitis viruses and other infectious agents can live much longer--also, you do not want to be the first-case-ever for something. Clean up with commercially available antiviral/antimicrobial cleaner or wipe. ...Read more

How long does HIV live in semen and is dried cum still infectious?

How long does HIV live in semen and is dried cum still infectious?

Varies: It depends upon physical factors like how rapidly the semen dries, the temperature, where the semen is deposited, etc. This virus seldom survives long outside of the body unless it has a cell carrier. Semen can provide that as long as it remains wet. Once it is completely dry the virus will die. ...Read more

How long could HIV live in semen and is dried positive semen still infectious?

Yes, but: Live when wet. Still potentially infectious when dry. If you are HIV positive and not using barrier sex, you are seriously potentially infecting your partner. If you are having sex with an HIV positive partner....I can't understand that! ...Read more

In general how long would hiv be infectious in a small drop of blood dime sized outside of the body?

In general how long would hiv be infectious in a small drop of blood dime sized outside of the body?

Not measurable: Nobody's going to do the hard science required to give a definitive answer to this question, because nobody has gotten sick by contacting a blood drop like this. What we do know is the exposure to casual blood spills -- as in cleaning a cut on an infected child -- simply doesn't infect people. When HIV was untreatable, family members simply didn't catch the virus except through sex or IV drug use. ...Read more

HIV remain infectious outside the body? For how long? Contact with the urine of a soropositive person in a wound it's a risk?

HIV remain infectious outside the body? For how long? Contact with the urine of a soropositive person in a wound it's a risk?

Wrong question: Nobody ever catches HIV by exposure to infected blood or body fluids in the environment. Whether or how long the survives, or other biological reasons, don't matter. No risk and so no worries. (And by the way, urine never transmits HIV.) If you only have safe sex and don't share drug injection equipment, you will never catch HIV. Don't worry about other possibilities. ...Read more

How long outside the body can a drop of blood with HIV remain contagious?

Very quickly: Hiv can not live out side the human body host for a long time. If the blood is dry its most likely not contagious. If its still wet or less than 10 min, it may still be contagious. Always protect your self with condoms and rubber gloves. Bleach can kill the virus and other bacteria on contact. ...Read more

How long can HIV remain contagious outside the body inside a drop of blood?

How long can HIV remain contagious outside the body inside a drop of blood?

Not long: The virus requires temperature very close to 98.6 and proper moisture. Exposed to an open environment without these conditions, it begins to die immediately, especially in small volumes. It might still be advised to use protection in direct contact with contaminated body fluid spills, but the risk is very low outside the body. Take care ; be well. ...Read more

Can you explain why a person who has recently become HIV positive is more contagious than someone who was diagnosed 5?

Not necessarily: A person has a higher chance to transmit the virus when their viral load is high; however someone with a low viral can also transmit it, so regardless when a patient is infected, if their viral load is very high she/he has a high probability to transmit it, also if there is genital lesions the risk of transmission is also high, acutely infected patients have high viral load initially. ...Read more

Is there any other sexual infectious diseases that cause death other than hiv?

Is there any other sexual infectious diseases that cause death other than hiv?

Yes indeed: The most common by far is HPV causing cervical or anal cancer. Next probably is hepatitis B, which can prove fatal over time, either directly by liver damage or from liver cancer. Syphilis very rarely is fatal in adults, but occasionally causes congenital infection with fetal death (miscarriage or stillbirth). Extremely rarely, complications of gonorrhea, chlamydia, or herpes can be fatal. ...Read more

Ciclopirox drug completely eradicates infectious HIV from cell cultures......How true is this?

Maybe, but...: It's possible that it does, at least according to the press release that got so much attention. Then again, lots of things kill hiv...Soap and water, for example. What we need is something that extracts HIV dna from human dna. I doubt that this toenail cream can do that! ...Read more

How long can HIV live in blood, and for how long is HIV positive blood still infectious outside the body?

How long can HIV live in blood, and for how long is HIV positive blood still infectious outside the body?

HIV longevity: This is a good but complicated question.

Hiv in the blood is found in the common viral form and also as the dna that would be found in the nucleus of all of the blood cells as well. Blood cells usually die off in 120 day cycles, but this could be lessened as the cells are destroyed by their being taken over as HIV mini factories. ...Read more

Dried HIV infected blood, is it contagious?

Dried HIV infected blood, is it contagious?

HIV: If the blood has dried long enough for the cells within the fluid to have died the HIV will also succumb to drying. But you must remember that just touching infected blood is not going to transmit the virus unless there is a break in the skin or the blood is somehow transferred into your mucous membranes or bloodstream. ...Read more

When after initial infection is HIV contagious but test results still show negative?

Uncertain: Any HIV test will have false positive or false negative possibility in the test result. However, most of the results are dependable and accurate. After the treatment, the virus in a infected body might not disappear but turn into a sleep mode and then will test in negative. Unless some other factors turn the key on and it will become active again. ...Read more

How long after initial infection is HIV contagious but the test results still show negative?

Probably from 1-6 mo: This window apparently can vary with the individual seroconversion. The recommended testing of patients is at initial exposure, at 6 weeks, at 3 months, and at 6 months. Many specimens positive with screening elisa are indeterminate on western blot, and so can be tested by immunofluorescence assay (ifa) more than one month later. So it must take up to 6 months to get positive test results. ...Read more

Could use your help docs! My brother is HIV infected and if his unwashed underpants were left in the bathroom for about 3 weeks. Can virus be still infectious?

No: In fact, you can hug him, kiss him, tell him how fortunate you feel that he is your brother, camp out and share a sleeping bag, use the same eating utensils, towels and toothbrush, hug him after a long, sweaty, shirtless run, and you'll remain uninfected. ...Read more
